fication as before, but instead of 0, the actual volumes, in fractions of a cubic centimetre, 
of the carbonic acid are given in the column designated C0 2 . In calculating the coeffi- 
cients, a slight correction had to be applied to the observed pressures when the volume 
of the carbonic acid was not precisely the same at the corresponding observations.

From Tables X. and XI. the values of a! from 64° to 100° referred to the unit pressure 
at 0° are easily calculated. In the next table the values of a! at the different parts of 
the thermal scale are given, p being the initial pressure in each case.
