Corrections for spheres = — 0'01825. 
Other corrections = — 0'00087. vx = 0'32053. 
Deduced specific heat = 0T96.34. 
After these two experiments, the total mass of gas was passed through an 
equilibrated U-tube containing phosphoric anhydride, with the result that the 
drying tube lost 1 milligramme in weight. The following experiments afforded the 
corrections for the spheres given in Table I. The minus sign applied to the numbers 
in column w is used to indicate that the excess precipitation was on the active vessel, 
and hence the correction is subtractive from the apparent result for the gas.

A fresh mass of gas was now introduced, and the experiments contained in 
Tables III. to IX. made upon this sample, successive quantities being liberated at 
the conclusion of each series.
