Sometimes we find it placed not above but below the level of the groniid, bo that dirt and spriDkliug water flow in. Even where every precaution has been taken, and shrubs have been planted around the inlet as a protec- tion against the dust, it is not always possible to obtain air entirely free from it.

Additional means of purifica- tion will in that case have to be used, such as allowing dust to settle in a large room, or removing it by an air filter or a spray.

Dust may also mix with the air further on in its passage through the pipes and fluea. To prevent this, these must not only be smooth and tight, and con- Btructod so as to be easily cleaned ; but both these and the dnst-chambers must be cleaned frequently.

The removal of the foul air in a school-room is nanally effected by means of a flue in a partition wall near the. This baa two openings, one near the floM and one near the ceiling, both of which may be clJfed by means of dampers or doors.

With respect to the details of managing the ventilat- ing apparatus, the upper of the two dampers or doors mentioned above, namely, the one near the ceiling, is to be kept open when there is no artificial heating, as are also the ventilators sometimes found in the opposite wall near the floor.

During the heating period on the other hand the air is to be removed by the lower opening in the ventilat- ing fine. The influx of fresh air is to be regulated according to the outside temperature and the outside air currents by the proper setting of the dampers.

That all this may be done aceurately, it is advisable to have the regulations for the use of the ventilating apparatus posted in every achool-room.

The window panes are in this case fixed into frames which in outside windows are hinged at the top, — in inside windows at the bottom. These outer and inner hinged -sections are so connected that they open and close at the same time, and there should be a convenient device for managing them from below.

The inner one also has side guards of tin to prevent the cold air from falling directly on the pupils sitting near. In this case, one of the upper panes consists of horizontal glass strips 10 cm.

The influx of air is regulated at will by turning the strips. Among other things, they have the disadvantage of letting the air which enters sink directly to the floor and spread over it in a gradually thickening layer.

Castaning has lately suggested a system of window glazing which may prove useful for ventilating purposes- in schools.

Two panes of glass are put in parallel, like the panes of a double window and so as to be from 8 to 10 cm. Outside air will B i. It is also desirable to sup-, port the free edges of the panes with thin iron guards to make them more secure and keep them from break- ing easily.

But even if all ventilating arrangements arc lacking, we can do much for the improvement of the air in school-rooms by opening windows and doors.

To be sure, when the school is in session, the opening of windows is nccessavily restricted. During the winter, the cold air would rush into the room and often lower the temperature too suddenly and expose pupils sitting near to the dangers of catching cold.

In summer, the noise in the street is often so great that, with open windows, lessons would be much disturbed. On the other hand, all class-rooms must be ventilated at the end of every lesson, both winter and summer, by opening all doors and windows.

The length of this airing should be governed by the weather; in Dresden the following rule has been proposed: How great a reduc- tion in the amount of carbonic acid in a room may be made in this way is shown by figures from Dankwarth.

After doors and windows had been opened, with four persons remaining ja the room, he found the foUowing a. While the ventilation is going on, the pupils go into the yard or corridors, and in this way get a little exer- cise and bring fresh air back with them in their cloth- ing.

The hall windows are accordingly opened during recitations and closed dnring recesses when the rooms are being ventilated. It is especially necessary to have prolonged ventilation of this sort between the forenoon and afternoon sessions, though it is gen- erally omitted entirely in cold weather, Accordingly, a decree of the Prussian Cultua-Minister rightly re- quires that the windows of class-rooms shall be open even at night in warm summer weather; at other times till dark, and from four in the morning.

Experiments made at the Hygienic Institute of the j University of Budapest testify to the success of this plan. During the summer the windows were first kept open dnring the day and closed at night, and then the reverse ; and in each case the temperature of the room was compared with that of the outside air.

On the other hand, if cleanlineas does not prcviiil in the school-room and the air is constautly being pol- luted by filth, no amount of ventilation will prove sufficient.

Cleanliness should extend in the first place to the pupils themselves. Not only ought their hodiea to be scrupulously clean, but also their clothes and shoes.

In connection with this matter the school shower- baths introduced by the city of Gottingen deserve more attention from higher institutions of learning than they have hitherto received.

For one thing they promote the cleanliness of the skin; and for another, they lead the pupils to desire clean underclothing. The school should provide ample facilities for the pupils to wash themselves.

Pupils with diseases that infect the air demand apeeial ] attention. Those with an ill-smelling discharge from 1 the ear mnat he suspended until completely cured.

The pestilential odor from perspiring feet sometimes defies all treatment; but even in this case we ought to insist at least on an attempt at betterment.

The roost effective measure against the odors from ulcer- ated, decaying teeth ia the introduction of a regular care of the teeth; and the school must do its part to Cleanliness must also be mainlained with respect.

Since dirt and dust coUest mostly on the floors, the proper construction and care of these is of great importance.

Too soft wood or too narrow boards must not be used. The first slivers easily and is not durable enough; it, moreover, absorbs moisture readily and dries very slowly, so that rooms with such floors when scrubbed have a smell even the next day.

Too narrow and lathlike flooring increases unnecessarily the number of cracks into which dust may settle. Matched floors of oak or American hard pine are prob- ably the best for schools.

They must in any case be kept in order, and any cracks or seams that may arise must be closed up at once. Linoleum has lately been used in many places as a covering for achool-room floors.

In fact, it fulfills all the requirements that have to be made of a good floor. It is elastic, waterproof, wholly free from cracks or holes, permanent, and very durable.

It has the further advantage of deadening the noise made by the feet of the children; and it can be easily und thoroughly swept and washed.

In the ease of schools with two sessions this may best be done on the free afternoons of Wednesdays and Saturdays.

Daily sweeping would be still better. To prevent the raising of dust, the floor must be covered with plenty of wet sawdust, tanning bark, or turf powder, which should have been moistened with warm water.

With dry sweeping the dust cannot be thoroughly removed. Since entries, corridors, and stairways are particu- I larly exposed to dirt, two sweepings per week will not A be enough for them ; but they must be swept daily with [ wet sawdust or the like and be scrubbed every week.

One or two wet sweepings per week is sufficient for the assembly halls, since they are less used ; but they ought to be washed out several days before every sehool festival.

Libraries, physical and natural science cabinets, and chemical laboratories do not need to be cleaned so often ; brushing them out once or twice a month in the wet way will be sufficient.

Oiled and parquetry floors should he cleaned with warm water, soap, and scrub- bing-rag; and unoiled floors with warm water, sand, soap, acrnhbing broom, or brush.

In like manner the wainacoating and furniture ahould be washed with warm water and soap, as should also the windows both inside and outside.

Furthermore, all door knob a, mountings, lamps, gas fixtures, chandeliers, busts, pic- tures, charts, and blackboarda, aa well as all heatiug apparatus, stoves, etc.

Special care is to be exercised in cleaning the books belonging to the teacher and the school library, the history collection, and the physical and chemical apparatus.

This should be done under the direction of the librarian and the corresponding department teachers. The shelves should first be wiped with a moist cloth and then rubbed with a dry one.

How detrimental dirty gymnastic halls may be to the health of the pupils has lately been brought out clearly by F. Schmidt, Die Staubschiidigungen beim Hallenturnen und ihre Bekiimpfung.

They may even act as carjriers of pathogenic bacteria aud produce infectious diseases. The entrance of the germs of consumption into the most delicate alveolar parts of the lungs is especially promoted by deep breathing and therefore by gymnastics.

The bringing in of duet into gymnastic halls is. Pupils should on this account before entering put on clean gymnasium shoes in special dressing rooms.

To prevent the production of dust in the exercises, mats should be used as litde as possible. Those made of cocoa fibers ought to be discarded altogether.

Aside from the fact that it is easy to slip on them, and that they can not be used for high jumping, they are dust catchers of the first order.

On the other hand, little dust can get into mats with leather covers on both sides, especially if the seams have been care-, fully made.

After having been used they should he placed so as not to bring the dusty underside of one into contact with the upper side of another.

After such cleansing, the walls are to be dusted dry, and the apparatus then wiped off with a moist clothe It is also a very good plan to clear the air at the end of every gymnastic lesson by sprinkling with a hose or sprinkling can, the former having the preference because it enables us to reach the upper layers of air.

That the miasma from closets can very greatly pollute the air is sufficiently well known. These ought therefore to be located in out-houses and connected with the main buildings by covered walks.

If they are placed in the school building itself, they ought to be accessible only from the corridors, and that by means of an ante-room which is easily venti- lated.

Between the closet and coridor there should be two self-closing doors. To make it possible to clean the floors more easily they should be made waterproof.

The bowls must also be waterproof and had better be made of castiron or stone-ware. CaakB ought to have overflow pipes with catch basins underneath.

They should moreover be placed in special, easily accessible chambers with waterproof floors and plenty of light and air. Great care should be taken to give the discharge pipe an air- tight connection with casks.

Where vaults are used for school privies, they should have a cement wall separate from the walls of the Bchool-house and should be impervious to water, the inside, the cracks should be filled with a coating of asphalt.

To facilitate emptying they should have concave bottoms and concave corners. They mast also have waterproof and fairly airtight coverings.

Whatever the kind of closet in use in a school, it is absolutely necessary to keep it constantly clean, and as odorless as possible.

Since eapenence shows that the reverse is often true, directors and teachers ought not to consider it below their dignity to inspect them repeatedly.

Aside from this inspection, the scouring of the floors and the seats once or twice a week regu- larly will best promote cleanliness. Foul-smelling gases are best removed by a ventilating flue extending from the cask room or vault to the foundation wall and then up over the gable of the roof.

If it is built near a chimney or if a flame is kept burning in it, the current of air generated will promote the escape of miasma.

For deodorizing or disinfecting the contents of the closets, turf powder deserves high recommendation, especially if super-phosphate in the proportion of 1 to 5 is added.

The latter at the same time increases the value of the excreta for fertilizing purposes. Lime may also be used as a disinfectant when added in sufficient quantities to render the contents strongly alkaline.

For this purpose 2. This process has this disadvantage that it is difficult to get the lime everywhere in close contact with the refuse materials.

Where deodorization and disinfection do not take place, the vaults should be emptied by means of a pump as often as possible, — at least every two or three months, provided they are not filled before.

The pungent odor given off by urinals because of the liberation of ammonia in the decomposition of urea, should be removed by a permanent flow of water.

If it is impossible to arrange for the flow of water, the wet places should be sprinkled regularly with powdered carbolic acid, which is usually colored red to prevent poisoning.

According aa heating apparatus ia designed for warming single rooms or several rooms at the same time, we may speak ol separate and general heating, respectively.

For the former stoves are used and for the latter large central heating plants. To settle the question whether stoves or central heat- ing plants are to be prefeiTed, economical, technical, pedagogical, and hygienic items must be considered.

As to economy the original outlay for stoves is less than that for central plants. For even the cheapest central plant, namely the hot air system, costs about 65 cts.

In making this comparison we must, however, take this fact into consideration that the stoves heat only the school-rooms and offices, while central plants also heat the stairways, corridors, ante-rooms, water-cloaeta, etc.

The operating expenses for stoves are also greater than those for central heat- ing plants. In 30 schools in Vienna it was found that the annual expense for fuel and janitor per cbm.

Prom a technical point of view the disadvantages of atove-heating become still more apparent. It is well- known that schools especially those of larger cities owing to the expensivenese of building sites, are liable to suffer from lack of room.

This evil is counteracted to a certain extent by using central heating plants, because these are located in otherwise almost useless rooms in the basement.

On the other hand if stoves are used, they not only occupy more or less room them- selves but some floor space is also lost by shortening the neighboring seats in order not to expose individual pupils to extreme heat.

Another technical objection to the stove is the in- convenience experienced in caring for it. It is evi- dent that to supply a number of places with fuel takes more trouble than to supply only one, and also that it is more burdensome to attend to more than one fire than to attend to one only.

Lastly, danger of fire increases with the increase in the number of stoves, whereas the concentration.

From a pedagogical atand-point it may be said that the repeated attention required by stoves especially the old style iron stoves, disturbs the work of the school.

Moreover, when the temperature is either too high or too low, the janitor has to be notified and this again interrupts the recitations, while with the more recent central plants the temperature of the room can be ascertained outside and can be regulated without entering the room.

In the discussion of the heating question, however, the hygienic side is of pre-eminent importance. The ideal in this respect is to have an absolutely uniform temperature throughout the room, since it is disa- greeable to have a rapid decrease o temperature from the ceiling to the floor.

In the latter case the head is exposed to a high and the feet to a low temperature, while the old Salernitan rule demauds that the head be kept cool and the feet warm.

With a stove, as we know, it is impossible to heat a given room unifonnly in all its parts. I Another hygienic advantage which the central has I over the separate heating method is that it brings more I air into the room.

A stove will serve far less aatiafao- 1 torily for this purpose, since it can he only of moderate I size, if the first cost and the running expenses are not I to be too great ; and it will therefore not be able to I bring about the required changes of air in the room.

I On the other hand, with a central plant the introduc- I tion of pure and the removal of impure air can be I regulated in a mathematically definite way.

This en- I ables us to furnish the amount of air required in any I given place, I Accordingly, where the location and construction do I not prevent it, large school -buildings ought to be pro- I Tided with central heating plants.

In fact they are 1 found in the public schools of most large cities, as for 1 instance almost without exception in Berlin, Hamburg, I Munich, and Frankfort a.

The use of stoves I may, however, be considered allowable in schools with I only a few rooms, since the hygenic disadvantages are I not so great that stoves must be absolutely forbidden.

I Stoves may beat he placed near the middle of I the long wall opposite the windows. Tile stoTes are not well adapted for Bcliool purposes because they heat up too slowly, fur- nish insufficient ventilation, and cousume too much.

Nor can the iron cylinder or cannon stove — so-called on account of its shape— be recommended for schools. The brisk fire in these stoves, it is true, draws the air from the floor of the school-room, and thus aids ven- tilation; but as an offset, they consume a great deal of fuel and must bo filled repeatedly.

But regulable reservoir stoves, which have a large jacket or casing and heat the incoming air only mod- erately, may be said to be satisfactory.

Of these there are many diGerent kinds. AVe shall mention only the Jacobi or Meissiier, the KaiserlaJtern, and Wolpert and Meidinger, reservoir stoves, the Kiiufler and Keidel patented stoves, and the somewhat similar Irifh and American base burners or self-feeders.

According to the test made by the hygienic institute of Berlin, the Kiiuffer Parlor stove and the large Keidel patented stoves keep the most permanent fire.

This holds true of the smaller ones of this kind only when anthracite is used. Within the wide casing of the Keidel stove, the incoming air from the outside is only moderately irarmed; and a sufficient quantity — about ten times as mucli B8 is furnished by the Meidinger stove, — is introduced into the room withont creating drafts.

The disadvantages of heating with illuminating gas, according to Ostender, are, aside from the heavy running expenses, the vitiation of the air by overheated heating surfaces and filling the school-room with gas.

Meidinger, however, has proved that these criticisms tre not correct. But we must concede the greater expense of gae heating. For one room the expense per hour was, for in- stance, in Cologne, where gas is 3J cts.

Even with the gas at 1 ct. On the other hand, the same amount of stove heat costs only IJ cts. The amount utilized varies between The expense aside, gas stoves have these advantages in their favor, namely, that they require no special fire- man, no room for fuel, no removal of slag and ashes, and that they can be attended to without the least difficulty, since they can be turned on or off at any moment, thus making the regulation of temperature in the school-room very much easier.

In the higher schools of Hamburg where gas heating is used, it ac- cordingly gives complete satisfaction. Whatever sort, of a stove the school may have, the teacher needs to keep a watchful eye on the following points in overseeing it: In the first place, gases from the combustion must not be allowed to escape into the room.

Although many of them produce only a feeling of discomfort, others, especially carbon monoxide, are very detri- mental to health.

On account of poisoning by carbon monoxide, which escaped into a school-room from a defective stove, the pupils showed the following symp- toms up to the fourteenth day: Pain in the forehead CARE OF STOVES and in the temples, heaviness in the head, dizziness, humming of the ears, weakness of memory, dullness, partly sleeplessness, partly sleepiness, pain in the breast, weakness of the legs, lessened patellar reflexes, coated tongues, nausea, diarrhea, and pallor.

It is now believed by many that the red hot walls of an iron stove permit the escape of carbon monoxide. This idea was first defended by Morin.

He based his conclusions on the investigations of St. Moreover, the fire pots of these stoves are lined with fire brick, so that they are in general not liable to get so hot.

Though it is an assured fact that the gases from combustion, especially carbonic oxide, do not pene- trate the walls of iron stoves, such gases may, never- theless, under certain conditions escape from any kind of a stove.

This is least to be feared when the fire is in full blast, because the great difference of tempera- ture between the inside and the outside of the stove gives rise to pressure toward the inside.

In this case the gases do not rush out of the pipes, but on the contrary, air rushes into them. It is only when a stove has been neglected and allowed to develop craoiksss — HEATING which is often the case with school stoves — that gases can escape, when the fire is well under way.

The escape of gas occurs, however, very readily when the fire is being started, because the pipes are not then sufficiently warm to produce the necessary draft.

At such times, especially where there are con- tractions and curves in the pipes, the gases inside may develop a greater pressure and consequently escape into the room.

He must be particularly instructed not to close the dampers in the stovepipe and chimney too soon. With the draft completely closed in this way, carbonic oxide gas, which is a product of incomplete combus- tion, is formed, and escapes into the room through the door or other openings in the stove.

Since even dam- pers with holes in them do not afford sufficient protec- tion against this evil, it it is better to prohibit the use of dampers altogether in schools.

Central Heating Plants These are designated steam, air, or water heating systems according as the heat conducting agent is steam, air, or water.

Several of these agents may, however, be used simultaneously when we have steam- water heaters, steam-air heaters, etc. Where this method is used complaints from the teacher are often heard.

The most general one is that the air is too dry. This dryness is, however, frequently oniy apparent. If dust, for instance has settled on the heating surface of the furnace or if dust laden air comes in contact with it, the dust particles are scorched ; and burnt products are produced, which irritate the mucous membranes of the throat and eyes, causing a disagreeable feeling of dryness.

The temperature of the heating surface must therefore be kept low ; and the settling of duat on it must be prevented as far as possible.

The first can be done by lining the fire-pot and adjacent parts with Chumotte stone ; and the latter, by not haviug large horizontal heating surfaces, and making those we have, smooth and not corrugated outside, to facilitate cleaning.

Teachers must see to it that the cleaning be done with regularity. The air may, on the other hand, really become too dry in hot-air heating. Whether this is so or not can be determined by the relative humidity, that is, the ratio of the amount of aqueous vapor in a cubic meter of air to the maximum it might contain at this temperature.

One of them would without the knowledge of the other produce different degrees of humidity in the air of a room for the other to describe by his feelings.

Neither could do this, since the temperature of the room and the general condition of the body played too great a part.

For this reason only limiting values, wide apart, can be given as to the proper degree of humidity in a school-room. According to Eubner there should be: Zeitschrift fiir Schulgesund- heitspaege, , No.

If we assume that 1, cbm. If there is a lack of moisture, we should aHcertaln whether the water tank in the heating chamber has an evaporating surface large enough to fulfill these requirements ; and if it has, whether it is always sufficiently full of water ; the self -regulating stop cocks may sometimes be.

Another defect often found in hot-air heating is the unequal distribution of the beat in the room. In another room heated by the hot-air system, a thermometer hanging 0.

This difference of temperature between the different horizontal layers of air in a school-room is first of all detrimental to the teacher. The pupils are similarly affected, and manifest it by yawning, by inattention, and by an inclination to rest their heads on their hands.

According to what has been said, it would be well for teachers employed in schools heated by the hot air system to measure the temperature repeatedly in different parts of the room.

It is true, that such differences when found can be remedied often only with great difficulty, and sometimes not at all. Zeitschrift fiir Schulgesundheits- phege, , No.

To accomplish this we should have to iucrease the cross-section of the pipes in the wall; this would require a change in the building and often even a complete reconstruction of the school.

We must note, finally, that the above mentioned differences of temperature, as a rule, occur only with old hot air systems, while the more recent give in this respect very satisfactory results.

Hot Water Systems heat the water which serves in this case as the distributing medium in conducting pipes, which are either open or closed to the air.

This is called the warm water or the low- pressure system. With closed pipes, or the so-called hot water sys- tem, the temperature of the water can be raised as high as is desired.

The medium pressure system is somewhat better. Moreover, the high pressure may prevent the valves which regulate the heat from working satisfactorily.

The necessary pipes or flues in the walls would be lacking for hot-air heat- ing, whereas the small pipes of this medium pressure svstem can be introduced anvwhero without much difficulty.

Warm water systems are, however, at all ]VMnts bet- ter than hot water systems. Steam beating systems are coming more and mora into use.

These are also designated respectively as low or high-pressure systems, according to the press- are in the pipes. High pressure steam systems are probably never installed in schools, because the use of high-pressure boilers in inhabited buildings is forbid- den on account of the danger from explosion.

Like all other steam and water systems, they have this advantage over the hot-air heating that with them ventilation and heating are separated.

One may be in operation with- out the other, or they may work together in varying degrees; whereas the closing of the register in a hot- air system reduces the ventilation to a minimum.

An- other advantage is the low temperature of the heating surface in the low pressure steam system, the ntUity of which has been discussed before.

To prevent a waste of fuel with a continuous fire, the draft in the furnace and consequently the heating itself should be regulated automatically by the steam pressure in the boiler.

When, for instance, the radiator on account of a high temperature in the room gives off less heat, it increases the pressure in the boiler.

This increased pressure closes the furnace draft and lets in less air to the fire, which then quiets down a little. If, on the other hand, the radiation of heat is increased, the steam pressure decreases and the draft is opened and the amount of air admitted to the fire is greater.

Lately the indirect low-pressure steam systems have been recommended more strongly than the direct low- pressure steam system.

With respect to the last point, the indirect low-pres- sure steam systems have a further advantage over the hot-air systems.

With the latter, the air may be pol- luted by gases escaping from the cracks, while this is absolutely impossible with the former.

According to reports from Vienna these indirect low- pressure steam systems have proved eminently satisfac- tory in the schools of that city; and will therefore in the future be used exclusively.

With a good plan, proper installation, and careful operation by an experi- enced fireman, no inconveniences at all can arise from them. The former have the advantage that they can not be put away or knocked down; the latter that they make the cleaning of the room easier.

Since the heat takes eilect only after some time, it is best, especially when the children are young and the weather is very cold, to give them some gymuaatic esercisea, or else allow them to run a few moments on the play-ground till the rooms become comfortable.

A mistake is often made at the Christmas or Easter vacation by not beginuing to heat the building one or two days before school opens.

If the heating ia only , begun the morning of the first day it is impossible to raise the air in the now thoroughly cooled rooms to the proper temperature.

The heating apparatus is, also, usually overtaxed at this time because the fireman tries to do in a few hours what it would take him at least a day to accomplish.

Hot-air furnaces are es- pecially liable to be ruined in this way, and an over- heating of the fire-pot and burning out of the grate has been observed even in the case of the low-pressure steam system.

The temperature consequently fell to Noth with standing this, we must aim at a constant temperature iu the school-room and for this purpose test it repeatedly, A thermometer should accordingly be hung up in every class-room about 1.

A standardized thermo- meter had better be procured, if the expense does not have to be avoided. Zeitachrift fiir Schuigp- aundheitspflege, , So.

In Germany, we often find the tempera- ture at the end of every recitation recorded in the class book ; but a curve gives a more evident picture of the matter than a table of figures, and is just as easily constructed.

In order to maintain normal temperature in school- rooms, attempts have lately been made to assist the fire- man by means of instruments which would indicate the temperature of the rooms by some signal near the furnace.

To this class of instruments belong the dis- tance thermometer of Bonnesen, and the central ap- paratus for electric temperature signals by Bastelmann and others.

The former consists of a barometer tube placed in the furnace room in the cellar; of a tin cylinder filled with absolutely dry air and placed in every room; and of a capillary lead tube, which con- nects the cylinder with the short arm of the barometer.

A change of temperature in the room causes a change of the pressure of the air in the cylinder, which is- then communicated by the capillary tube to the fur- nace room, where the temperature of the rooms can be read on the scale of the barometei.

These thermometers are suspended in the Bchool-room and are connected with the signal board When the mercury rises bo that it touches the platinum wires, an electrical circuit is closed by means of pres- sure on the corresponding contact buttons a, b, c, d, e, f, in figure 10 , and this releases an indicator on the signal board.

These in- struments should be tested not only when they are put up, but every now and then afterwards by the physicist of the school.

For it is olear that an incorrectly constructed school bench occupied by pupils daily four to six hours for twelve years must necessarily prove injurious to their physical development.

Moreover, the school work suffers, since a seat which compels pupils to sit or stand uncomfort- ably leads to rapid fatigue.

The two accordingly resemble the rockera on a rocking chair; and so touch the seat in two points only. Now two points are not sufficient to fix the position of a plane.

A third is necessary; or else a line par- allel to the line joining the points of contract of the twe seat bones. If a plummet be dropped from the centre of gravity of the trunk upon this triangular supporting surface, it will strike it in a point back of the connecting line of the two seat bones.

This may, accordingly, be called the backward sitting position. Besides this we haye the forward sitting position. In this the body rests on the two seat bones and on the line of contact of the thighs with the edge of the seat.

If we imagine a perpendicular dropped from the centre of gravity of the trunk upon the plane thus determined, it will strike it in front of the connecting line of the seat bones.

The trunk can not only be moved aa a whole on the hip joints, but since it has inner articnlationa it can change shape within itself.

To prevent the trunk from getting such curvatures and at the same time to keep it from falling backward or forward in the corresponding sit- ting positions, a great many muscles have to be ad- justed.

They, however, become fatigued in time and we find in the case of tired, feeble, or sleeping persons that not only has the whole body fallen forward but the spinal column has received a certain curvature.

The muscles employed in sitting upright must, there- fore be given a chance to recuperate by being relieved now and then.

There is no other way of doing this than by leaning against the back of the seat in the backward sitting position; and in the forward position by resting the arms on the top of the desk or placing the breast against its rear edge.

The latter should not, however, be permitted, since the pressure on the chest will interfere with breathing, and endanger the lungs.

The only thing left is to lean against the back of the chair or place the arm on the desk. That an upright position is possible in the latter case will be made evident by figure 11, the reproduction of the photograph of a writing class.

From what has been said and for other reasons, the following are the requirements for a good school desk. The seat should be of such a height that the feet may be placed evenly on the floor or foot rest, while the upper and lower legs make right angles with one another.

Its height must, therefore, be somewhat less than the distance from the sole of the foot to the knee. Hence a royal decree of Saxony demands that for the above named ages the height of seats without foot-boards should be , , 35, cm.

The width of the seat had better be about two-thirds the length of the upper leg, since a person likes to sit so as to have one- third of it extending beyond the seat.

The table below is constructed in accordance with this plan. The little differences in the requirements are due on the one hand to the difficulty of ascertaining just how much of the upper leg should rest on the seat, and on the other, to the fact that the upper leg varies in length with different racial and social conditions.

Kunze, therefore, demands a diiference in height between the front and rear of the seat of 1 to 1. These seats are indeed very comfortable, hut it must not be for- gotten that the inclination of the desk must increase with that of the seat.

The front edge of the aeat must not he angu- lar but rounded, since it would otherwise exert a pres- sure on the popliteal veins and arteries back of the knees, and thus Impede the circulation in the lower leg and foot.

Joachim Camerariua , the friend of Melanehthon, not only advises in his " Maxims for Boys " that they substitute ball-playing, running and jumping, boxing and wresthng, for the disreptutable game of dice; but in his " Dialogus de Gymnasiia " he points to the gymnastics of the ancients as a model.

Humanists, like Sadolet, brought the gymnas- tics as well as other features of classical antiquity again within the circle of common interest.

Camerarius praises the Greek games particularly in comparison with the rough [and [excessive sports of our German.

The Jesuits have rendered particularly eminent ser- vice in the field of school hygiene. As is well-known, they were enterprising teachers, and founded not only I schools for their own order, but also academies in , which any young person might receive lodging, care, and instruction.

In the outline of their methods known aa " Ratio et imitatio studioram societatis Jesu ", which was issued for these institutions in by the general of the Jesuits, Claudio Aquaviva, the number of daily recita- tion periods as well as the amount of work to be done by the pupils will be found to have been re- stricted in a very reasonable way.

The schools and boarding houses of the Jesuits were, as a rule, hygi- enically well arranged; and the physical development of the boys was furthermore promoted by good board, daily walks, games, and long vacations.

In the second volume of his work: In the first section, he treats of the injuries result- ing from burdening the youthful powers of mind and body too early and too severely.

He urges that boys under eight shoula not be allowed to enter a Latin school, and then only if they are especially talented. Lessons must not begin too early in the morning; they should not last over five hours, and should be discon- tinued in extremely hot weather.

The desks and seats, he thinks, deserve special consideration. They must correspond to the aize of the pupil, and have comfortable and not too perpen- dicular backs, if deformities of the spine are to be avoided.

The author also discusses school punish- ments, home tasks, vacations, and the isolation of auch pupils as suffer f.

The last section is devoted to the " re-establishment and value of gymnastics in public education ". Here he recommends walks, excursions, tramps, and jour- neys, as veil as different exercises and sports such aa playing ball, climbing trees, walking on atilta, racing, ihrowing, danting, fencing, riding, swimming, skating, and bowling.

In order that pupils may be exposed to the least possible danger, he demands the establish- ment of public drill-grounds, and the employment of a special drill master.

He also enumerates a long list of precautions to be observed in the different exercises and games. While the work of Prank diacusaes school hygiene in general, that of the medical councillor, C.

Lorinser, Znm Schutz der Geaundheit in den Schulen. The essential energy of lite is lower; and in the same degree aa the senses have become more mobile and the impulses more impetuous, body and mind have lost in firmness and resistance.

The firat con- fuses and dulls the mind; the second retards the natural development of the body; and the third pre- venta recuperation from these effects outside of school.

He adheres rather to the opinion of J. Even though it occasionally missed the mark, it was nevertheless the alarm gun which aroused slumbering minds to action.

While it was partly rejected by the pedagogues Gotthold, Miitzell, Heinsius, and Kopke, it received the general approval of the physician Foriep.

He sums up his opinion of the matter by saying that the conseqiiences of overpressure can be observed among the pupils; and the cause is to be found in the haste of pupils, teachers, and parents ; and also in the increased demands by the present system of ex- aminations.

Important aid was rendered by the fact that King Frederic William III took notice of the work of Lorin- ser, and in a letter to v, Aitenstein, the Cultus-minie- ter, espressed his sympathy with the movement.

After that, means for removing the evils in question began to be considered; and on June 6, , appeared the famous cabinet order by Frederick WiUiam, IV.

With the exception of the short period of quiescence caused by the political situation of the time, the in- terest in physical training has grown rapidly ever since ; and the field of school hygiene has been steadily ex- tended and developed by physicians, pedagogues, and architects.

Instead of making general remarks about schools and school instruction, men now devote them- selves to exact investigations and the study of special problems.

Parow, Fahrner, Hermann, Schildbach, Kunze, and Buchner introduced the school-desk re- form; and they have lately been joined by Schenk and Lorenz.

Von Pettenkoffer, Breiting, and Eitschel have tested the air in school-rooms. Attention has also been given to the personal hygiene of the pupils and the so-called school diseases.

In the study of eye defects, the examination of 10, school children by Hermann Cohn was epoch-making; and he has recently been followed by von Arlt, Schmidt Simpler, von Hippel, Pfliiger, and Stilling.

Bresgen and Eafemann have pointed out that when breathing through the nose is obstructed, weakness of memory and attention is pro- duced.

To prevent the curvature of the spine so often caused by writing, Schubert and W. Meyer have advocated the introduction of vertical script. Gutzmann have suggested a new method of curing stuttering, and have attained note- worthy results in this line.

There is no lack of comprehensive treatises on school hygiene. Hygiene des Korpers nebst beilaufigen. Bemerkungen, , A Holder. Baginsky, Handbuch der Schul-Hygiene.

CHAPTER II The Light of the School-room Since we have undertaken to treat only of those facts ot school hygiene which the teacher himself can observe and to aome extent control, we refer the reader to the more complete works of Baginsky, Burgeratein-Ketolitzky, and Eulenberg-Baeh for a dis- cussion of buildings and sites.

In theae the necessary information can be obtained concerning the location and extent of the site and the different parts of the building, especially the foundation, facade, materials, stories, corridors, and roof.

In general, it should be the rule to have the sun shine freely into the room for several hours of the day, if possible when school is not in session.

Since Bunlesa rooms are generally damp and cold, people justly call them unliealthful. We know that on streets which run east and west, the rate of mortality is greater on the shady than on the sunny side.

Besides warming and ventilating, sunlight also disinfects. Pure cultures of most pathogenic bacteria do not grow in the sunlight but soon perish.

Sunny class-rooms are, therefore, to a certain degree, a hin- drance to the spread of infectious diseases through the school.

A southeasterly direction of class-room windows is to be preferred. This provides for the necessary light and warmth from the sun, does not expose the win- dow front to the generally prevailing west winds, and prevents the early and almost horizontal rays from falling into the room.

In this respect it has this special advantage over the pure easterly direction that the sun reaches the room later in the day and leaves it after a shorter time.

We believe that an easterly exposure is, next to the southeasterly, the most favorable, because here the sun shines into the room chiefly before instruction begins and not during the hottest part of the day.

To be sure, we hear the argument that in oar climate even at this time of the year the sky is often cloudy ; that the nearly perpendicular rays of the noon- day sun do not fall far into the room and are leas an- noying than the horizontal light of the morning and evening sun, and that the two hottest months aro mostly taken up by the summer vacation.

Xeverthe- lesB, as a matter of fact, the temperature in the eoutb- erly rooms rises very high in spite of all protective measures against the sun, since the southern wall and the layers of air next to it both become strongly heated.

It would be possible only with an easily regulated heating apparatus to keep the temperature of the room constant, with the win- dows now shaded and cool and now heated by the noon- day sun.

Zeitachrift fiir Schulgesundheitspflege, , No. Giinstigste Lage der Schnlzim- mer. We would not, however, advocate a westerly direction, because as stated above, it is the side exposed to the weather.

Wind and rain would often strike the win- dows, prevent their being opened in summer, and in large cities blow dust and smoke into the room.

A northerly exposure is admissible for drawing-rooms, and in fact to be recommended for this purpose, be- cause north rooms, not being open to the sun, need no blinds.

The light can therefore all be utilized; and it remains exceedingly uniform. If a northerly draw- ing-room is well heated and well ventilated, it is not likely to be injurious to health, notwithstanding the lack of sunlight, because pupils spend in it only a few hours per week.

The natural illumination of the school-room is closely connected with its orientation. For it is evi- dent that rooms facing the northeast, have more light in the morniug than those facing the southwest, while at noon the reverse is true ; and that rooms facing the south, other things being equal, receive more light than those facing the north.

SuflBcient daylight is of the greatest importance to the eyes, and therefore efforts have been made for a long time to ascertain in figures the amount of light in different parts of the school-room.

Seper- atabdruck aua Schillings Journal fuc Ga. In the case C, is a little deyice for regulating the flame, and a small scale at- tached to a mirror.

By looking through a slit oppo- site, the length of the flame, which is to be "2 cm. Along the full length of tube A is a millimeter scale.

In the middle of 5 is a reflection prism, one perpendicular plane of which is turned toward the middle axis of A, and the other toward the ocular h.

At the end of the tube B, opposite the ocular, is a square metal hot g to which a tube i can be attached to exclude light from the sides.

The Hght that goea to the ocular from here fills the left aide of the field of vision. On looking into the ocular one sees to the right only the light which comes from -4; and to the left, only that which enters through the box g.

If the two lights are equal in color and intensity the two parts of the field of vision merge into one with a Bcarcely noticeable line of divi- sion.

To enable the observer to give the light to be measared the same color aa the benzine-light, the ocular contains a slide with an aperture and a red and a green plate of glass, so that the photometer can at pleasure be set for white, red, or green, light.

A white slate, forming a part of the outfit, is fastened to a stand and placed in that part of the school-room where the light is to be measured. The intensity of the light thus measured is computed by means of a formula given by Weber.

The result gives the num- ber of " normal candles " which one would have to place at 1 m. In the accompanying illustration Fig. Zeitschrift fiir Instrumenten- inade, , Part 10, pp.

After the instrument has been placed on the spot to be tested and the lens turned toward the window, the base is made horizontal by the aid of three leveling screws and the plumb-line II E.

For this operation the plate P has to be moved so that the index m at- tached to it points to the zero mark on B. The base is level when the plumb is directly over a given point in it.

By shifting the lens L on the rod s an inverted image of the window sash, the roofs and steeples, as well as of that part of the sky visible at the place under investigation, is produced on a sheet of paper fastened with brass clasps on the plate P.

This paper is divided by lines into 3 mm squares. The reduced solid angle measures only the former, while under certain conditions the latter is predominant.

If the smaller types, which, hj the normal eye can be recognized in good light at a distance of 0. This will generally be true where no portion of the flky is visible.

These dark places are usually near the wall opposite the windows or directly adjacent to the wall spaces between them.

Moreover, Huth has shown in a school in Berlin that at a distance of meters from the windows the light was rednced to a thirtieth of its original intensity ; and in cloudy weather it fell below that of one meter candle.

If the light supply is insufficient in a school-room, what can be done to remedy the matter? Sometimes we may leave dark places unused, or else exchange them for others that have more light.

If this is im- possible, we must paint dirty ceilings white, and dark walls either light gray or green; but in neither case should the color be dazzling.

Above all, light must be given free passage through the windows. These must be cleaned carefully, and kept free from paint; and the blinds must be raised as high as possible.

A still better plan would be to fasten the blinds above so that they could not obstruct any part of the window.

The removal of vines and especially of trees which shade the windows improves the light in a sehool-rooni very much.

Light can also be thrown into a dark room by means of prisms and reflectors. The day- light reflector by F. Hen- nig of Berlin, the use of which will be explained by the accompanying illustra- tion Fig.

The corrugation increases the surface of re- flection and secures a better distribution of the light. Diamond type was read 13, and Bourgeois 19 em.

In correspondence with this, it was found photometric- ally that the amount of light was nearly twice as great. If the necessary light cannot be secured even by the introduction of reflectors, there is nothing to do but to enlarge the windows.

This has often been done in the schools of Breslau. In Prussia, according to the Royal Technical Building Deputation, the window and floor Bpaces must have a ratio to each other of 1: In Saxony, Wiirtemberg, and Lower Austria a ratio of 1: In enlarging the windows, care should he taken to have the apertures made rectangular, since arched or Gothic styles lessen the window surface unnecessarily.

The top of the window ought to extend as nearly as possible to the ceiling ; and the lower part must be 1 to 1. Zeitschrift fiir Schulgesundheitspflege; , No.

Walls containing windows should be bevelled both on the inner and outer edges, eHpecially at the top outside. The panes must be as large and the sashea aa narrow as possible.

The illumination may, furthermore, be too strong as well as too weak. Direct sunlight ahould not fall on the eyea or work of the pnpils, aa it will irritate the retina.

To prevent this, school -windows should have means of protection either on the outside or on the inside. Outside awnings have this advantage, that they can be placed according to the position of the ann, and so do not unnecessarily diminish the light in the room.

Thoy also protect the children from the heat of the snn and permit the opening of the win- dows. They are, on the other hand, expensive; and do not last long, since they are exposed to the weather.

This holds trne, also, of blinds and shutters suspended outside from the top of the window frame and held away a certain distance at the bottom by iron rods.

When they are drawn np they darken the school-room more than the awninge do. Common curtains which roll up at the top have the disadvantage not onlj of being usually out of order, but also of letting in light at the sides.

If people, nevertheless, will have them, they must be put up so as to extend a little over the window frame. Better than these just mentioned are curtains that can be drawn up from the bottom by a crank or such as are fastened in pairs at the middle of the window and can be drawn one up one down.

With the latter, it ia possible to leave the upper parts of the windows, through which the brightest sky light enters, uncov- ered, as soon as the sun permits.

Venetian blinds, whose alata can be set horizontally, diagonally, or perpendiculariy, are not auitahle for school-rooms.

In addition to having the light sufficient and not too strong, it is important to see that it comes from the right direction. The windows must, therefore, be in a wall lengthwise of the room and to the left of the pupils.

If the windows are ia front, the light will fall directly into the pupils eyes and irritate the retina. Another inconvenience from windows so located is described by Baginsky from his own experience.

Still stronger shadows, caused by the whole upper part of the body, appear when the windows are located behind the pupils.

Coneeqiiently the light from 4 B left is the only proper light, and hence is most I commonly used in higher schools. There still remains the question, whether light might 1 not enter the school-room from the two aides.

They say that with light coming I in on both sides places between the windows and in J the corners of the room are better lighted. Im Auftrage dea Kaiserlichen Statthaltera eratattet, von einer mediziniachen Sachv6r-.

But the facts which they cite to substantiate their opinion, namely, that those school- rooms which had the least number of myopic children received abundant light both from the right and left, we can not admit as a demonstration, because myopia is due to many other causes besides deficient lighting.

Prench hygienists have, themselves, repeatedly called attention to the fact that forms are recognized with great difficulty when light comes from two sides, on account of the absence of shadows.

And lastly, with this arrangement the right and the left eyes are illum- inated differently, which may give rise to the develop- ment of defective refracting power.

Lighting from both right and left can, therefore, be sanctioned only if sufficient light can be had in no other way. Windows both at the left and rear of the pupils should still more emphatically be prohibited except in cases of emergency.

If they are, neverthe- less, in use, the light from behind ought to be checked by dulled panes,]curtains, or similar devices. All other combinations of two-sided lighting are to be absolutely rejected.

This hap- pens most frequently in schools with two sessions in winter, when the first and last periods do not always have sufficient natural light.

But even at other seasons dense mists, fogs, clouds, etc. Boarding-schools must have it, at any rate. The electric light ranks first among the different kinds of artificial light.

It is white, and resembles daylight most closely leaving colors almost unchanged ; it does not contaminate the air; it involves almost no risk of fire; and it can be conveniently handled.

The flicker- ing, which is so disagreeable to the eye on account of the changes in intensity, has in consequence of recent technical progress wholly disappeared in the incan- descent, and almost wholly in the arc lamps.

Eulen- bergs Vierteljahrsschrift, , Vol. Such batteries are particularly serviceable in places like schools where a current is needed on the instant and for a short time only.

The arc light has, as is well known, great intensity and must be covered by ground glass globes, alabaster shades, or something similar.

It might otherwise cause inflammation and swelling of the conjunctiva, and photophobia, with spasmodic contractions of the lids and narrowing of the pupils ; also, hemeralopia, and possibly amaurosis.

Most of the light from the arc is caught by this reflector and thrown on the white ceiling. Many rays also strike the latter directly, and atill more the upper parts of the walls which are like- wise kept bright.

From here they are reflected in all directions and light up the remotest comers of the room uniformly ; and what ia most important they pre- heitsamkeit in Moakau.

Zeitschrift fiir Schulgeaund- heitspflege, , No. Zeitschrift fiir Schulgesundhev , No. The source of light is in this way wholly concealed from the eyes of the pupils.

How bright and pleasant such a light can he I have myself been able to observe in a school in Ham- burg, where the rooms were illuminated not by one but by several arc lamps with reflectors.

Two reflectors with faces opposite are placed on the wall, so aa to make a certain angle with it. The larger reflector has the shape and size of a German studio window.

The focus is in the middle of the smaller reflector, which is made of a variety of transparent materials. Half of the light falls on the objects to he illuminated after a single reflection from the large reflector; the other half falls on the small reflector and ia partly trans- mitted, partly reflected to the larger.

To a person in the room the large reflector looks like a luminous body several square meters iu area with nearly uniform brightness, having only in the middle a somewhat brighter spot.

Zeitschrift fiir Sclinl- ffesnndheitBpBege, , No. The instrument is made either with one or with two are lamps, the latter having the advantage of producing a more nniform light.

The strong points ahont the side reflector are that it gives a diffused light, which is not dazzling, but variable at will, and more evenly distributed than daylight.

While the latter is a hundred times stronger at the windows than at a distance of ten meters from them ; the light from the reflector shows an intensity of Accordingly he constructed hia reflector as follows: An adjustable prismatic glass ring 6 if suspended from this top surrounds the arc, under which is the opal glass shield L.

The school-room receives in this way a well distributed diffused illumination; shadows are insignificant; and the dazzling arc is completely concealed.

The electric light is doubtless the light of the future ; but on account of its costliness most schools will have to be satisfied with a diSerent kind of illumination.

Gas light and kerosene lamps must claim our attention. The gas arc-light of Butzke of Berlin and the similar Wenham light also gives an illumination suitable for jschools.

Both contain regenerative burners with the flame downwards. With respect to the Auer incandescent gas-light, re- cent opinions differ.

And this with its far greater brilliancy is the real illuminating body. One advantage of the Auer burner is that only a small amount of gas is consumed in comparison with the amount of light produced.

Finally, the incandescent burner gives a light of superior brightness, whiteness, uniformity and steadiness ; and produces only a small amount of heat, not enough to cause overheating.

For these reasons it has been recommended by the Prussian cultus-minister for use in public institutions, universities, etc.

Since its introduction, there has been a decrease in diseases of the respiratory organs, myopia, and cases of conjunctival catarrh.

According to a re- port by this body a gradual decrease of brightness can be observed in the Auer light. Its intensity and color, especially when the light is first introduced, irritate the retina; and the frequent explosions of the chim- neys endanger personal safety.

We can say with greater certainty that the Albocar- bon gaslight is not fit for school-rooms. It is true the flame does not flicker on account of the increase of the specihc gravitj of the.

Illumination by means of simple broad flame burners, — such as are often found, either with or without opal- escent glass globes, in halls for physical training, and in corridors, is also to be rejected for school-room use.

The flames flicker so much that, for this reason alone the light cannot be used for reading and writing; and, besides, they lack sufficient brightness.

Round burn- ers properly constructed are much to be preferred ; but they must be supplied -both with chimneys and with globes or shades. The chimneys answer a threefold purpose.

If they have a thickness of from 2 to 3 mm. The upward going rays should be reflected down up- on the pupils desks by globes and shades so as to in- crease the illumination,.

With regard to the use of kerosene lamps, the objec- tion is usually made that too much care is required to keep threm clean and in order; and that books and tablets are liable to be soiled by them because petrole- um vapors condense in the combustion on the cold reservoir.

There is no danger of poisoning connected with them, whereas gas escaping from leaky pipes con- tains, as is well known, the dangerous carbonic oxide.

They will not injure the respiratory organs, as impure illuminating gas will, which forms ammonia and sul- phuric acid during combustion. For a hundred candle power light, petroleum gives off grams of water, and gas ; and, what is still more important, petroleum under the same circumstances gives off liters, and gas liters of carbonic acid.

Renk, Uber die kunstliche Beleuchtung von Bdrsalen. Such a temperature will necessarily prove enervating for pupils and teachers alike.

Fur- thermore, hot flames cause a rapid evaporation of the moisture in the eye, and in this way bring about a feeling of dryness in this organ.

They also cause the face to become heated and red; and they produce headache, — all evils which are seldom found where petroleum light is used.

Whether gas or petroleum lights be chosen, the illumination must in every case be so great, that at all places in the room diamond type can be read by a person with normal vision at a distance of 0.

This is equivalent to a light intensity of at least 10 meter candles. Especially strong illumi- nation is required for blackboards, charts, etc.

And, lastly, the lights must be at least 0. Riibner believes this due not only to the high temperature but to the drying of the skin and the more uneven distribution of light and shade than is customary with sunlight.

We are thus led to consider one of the most important topics in school hygiene. Everybody knows that atmospheric air is composed of oxygen, nitrogen, water, and carbonic acid; and that the proportion of these components, with the ex- ception of water, is subject to but very slight changes.

In all tests, where and whenever made, the per cent by volume has been as follows: Lately the so-called precious gases argon, helium, and krypton, which were formerly counted with nitro- gen, have been discovered, and found to be constant components of the air.

It is not, as was first supposed, an ele- ment, but consists of the real argon, a solid, metargon, and a volatile gas, neon.

Outdoor air also has traces of ammonia, and nitrous and nitric acid. The chief cause of this is excretions from the lungs and skin of teachers and pupils.

To this must be added the carbonic acid excreted by the skin, although this is only a hundredth or at most an eightieth part of that excreted by the lungs.
