9.80 liters. On the contrary, during the period from 4 to 7 a. m. on the 

 experimental day, December 19-20, there was a decrease of 39.10 liters in the 

 amount of oxygen in the chamber. These and similar fluctuations in the 

 residual amount of oxygen are recorded in column c. 



Since weights rather than volumes are employed in many of the computa- 

 tions, the equivalent in grams of the volume of oxygen lost or gained to the 

 residual air is computed by dividing the volume by the factor 0.7, and recorded 

 in column d. The actual weight of oxygen admitted to the chamber from the
