B—C=volume of CO, eliminated, 
A—C=volume of O, absorbed. 
From these volumes the respiratory quotient (CO,/O,) is easily cal- 
culated, as are also the milligrams of carbon dioxide eliminated 
and of oxygen absorbed per gram of imbibed weight per day, 
using 1.96 mg. as the weight of 1 cc. of CO., and 1.428 mg. as 
that of 1 cc. of O,.? 
? The application of these dae bia is illustrated i in the following calculation of
