The chemistry of the alkaloids is treated in detail by Ame Pictet in his La Constitution chimique des alcaloides vegetaux (Paris, 1897); enlarged and translated by H.
Again he held that chemical phenomena are not governed by any peculiar laws special to themselves, but are explicable in terms of the general laws of mechanics that are in operation throughout the universe; and this view he developed, with the aid of thousands of experiments, in his Mecanique chimique (1878) and his Thermochimie (1897).
Arrhenius is specially associated with the development of the theory of electrolytic dissociation, and his great paper on the subject, Recherches sur la conductibilite galvanique des electrolytes - (1) conductibilite galvanique des solutions aqueuses extremement diluees, (2) theorie chimique des electrolytes, was presented to the Stockholm Academy of Sciences in 1883.

The thesis written for his doctorate, Application de l'analyse chimique a la toxicologic (1859), was followed by many papers on chemistry contributed to learned journals, and his Principes de chimie fondes sur les theories modernes (1865) reached its 5th edition in 1890.

Berthollet's most remarkable contribution to chemistry was his Essai de statique chimique (1803), the first systematic attempt to grapple with the problems of chemical physics.
