The values of Pj as well as the mean pressures in atmospheres are directly scaled 
from the plot of Amagat’s experiments, in which, as explained, pressure is plotted 
against density, and have little uncertainty about them. In the calculation of the 
mean pressures, as given in Table XV,, one atmosphere is added. The values of 
(Experiments 1 to 10 ) are obtained from Amagat’s table of pressures at saturation of 
carbon dioxide {loc. cit., p. 70). From this, too, we derive the following table, giving 
the masses of liquid and gas present at the initial temperatures of the experiments 1 
to 10, and the approximate temperature at which the liquid was entirely evaporated 
in each case.

The chart on the next page showing the plotting of the experiments contained 
in this paper, and those on carbon dioxide contained in Part I., reveals that the specific 
heat plotted against density follows a slightly curved line, convex towards density. 
The plotting could onl}^ be carried so far as the densit}" 0T50, owing to the presence
