ABBREVIATED METHOD OF COMPUTATION OF OXYGEN ADMITTED TO THE CHAMBER FOR
USE DURING SHORT EXPERIMENTS.

Desiring to make the apparatus as practicable and the calculations as
simple as possible, a scheme of calculation has been devised whereby the
computations may be very much abbreviated and at the same time there is
not too great a sacrifice in accuracy. The loss in weight of the oxygen
cylinder has, in the more complicated method of computation, been
considered as due to oxygen and about 3 per cent of nitrogen. The amount
of nitrogen thus admitted has been carefully computed and its volume
taken into consideration in calculating the residual oxygen. If it is
considered for a moment that the admission of gas out of the s
