DR. J. JOLY ON THE SPECIFIC HEATS 
After this, all experiments were carried out in the new form of calorimeter described 
in Part III, To connect its results with those obtained in the old apparatus, the next 
set (Table XI.) were made upon gas taken from the same bottle used for the fore¬ 
going experiments. There is satisfactory agreement with the results of Table VII. 
Table XL—W = 5'1585 grammes. Mean Density = 0’0604.

Correction for spheres = — 0'02062. 
Other corrections = — 0‘00045. -sr = 014658. 
Deduced specific heat = 0T7940. 
The next set (Table XII.) were carried out on gas prepared from bicarbonate of 
soda by pure sulphuric acid and pumped into the sphere through drying tubes (as 
described in Part I.). The impurity in this gas was found to be 1 part (of air ?) in 
1105 by volume.
