First appearance of Berthelot's second large memoir on themochemistry, a subject in which he laid the foundation stones.

"In the 1860s Berthelot was done with synthesis and turned to thermochemistry, the study of the heat of chemical reactions. In some of his work he had unknowingly been anticipated by Hess, but he went much further. He devised a calorimeter within which he could measure the heat of chemical reactions and ran hundreds of determinations. This work along with that being conducted by Thomson threw the science of thermochemistry into high gear."(Asimov).
