How to measure ventilation — Many writers on school hygiene give descriptions of methods for ascertaining WARMING AND VENTILATING 99 by chemical means the amount of c...arbonic acid gas in the air of a schoolroom. The test with lime- water is misleading and inaccurate, and some of the other tests involve a nicety of manipulation which can be expected only of a trained chemist. There is little need, at the present time, of determining the amount of carbonic acid gas in schoolroom air, for when the capacity of the room is known, the number of pupils in it, and the amount of air coming in, the con- dition of the air in this particular may be calculated with sufficient exactness.
