The ordinary method of collecting air samples is to employ two tonometer tubes with ground glass cocks, one of the tubes being filled with mercury. A fairly large tonometer will hold from 2 to 4 pounds of mercury, and the expense of an outfit for getting a number of samples, not to speak of its weight and bulk, is considerable. Another method is to make the collection in small bottles by the use of a mercury trough, which is also rather expensive, and involves some rather troublesome manipulations. Dr. Yandell Henderson suggested to me the use of acidulated water to replace the mercury in such a trough, and we found the results sufficiently accurate for our purposes. Since that time I have devised, and employed to a considerable extent, the small apparatus here described, as a very convenient means of collecting samples, and one which is well within the limits
