"In 1834 Dumas presented a long paper, "Recherches de Chimie organique", to the Academy of Sciences in Paris. In this he described chloroform and chloral and explained the mechanism by which chlorine acted upon ethyl alcohol. The paper was published soon afterwards (as offered here) and several years later was reprinted with the addition in the theoretical part of Dumas's theory of metalepsy."(Leicester & Klickstein "A Source Book in Chemistry", p. 320 ff.). - Parkinson "Breakthrough" 1834 C. - Partington IV, pp. 360 ff.
