Mendeleev's first step towards his chemical theory of solutions.

"After 1884, Mendeleev concerned himself with the expansion of liquids and in particular with the specific weights of aqueous solutions of various substances. He was able to conclude that in such solutions discontinuous relationships exist between the solvent and the solute, attesting to the existence of determinate chemical relationships - a necessary condition, according to chemical atomic theory. Mendeleev thus arrived at a chemical theory of solutions, which he opposed to the theory of electrolytic dissociation of dilute aqueous solutions set forth by Arrhenius."(DSB).

The volume contains further notable papers LECOQ DE BOISBAUDRAN "Séparation du Gallium d'avec les autres Éléments", pp. 176-271 - he discovered Gallium in 1877, this long paper describes describes the separation of a long sereis of other metals, also the rare earth metals. - 3 importent papers by FRANCOIS MARIE RAOULT on molecular weight of organic compounds, follwing up his discovery of Raoult's Law two years before.
