    MEMOIR On Deph logistic cited Marine Acid. By M. Berthollet.* The important experiments by which the nature of water had just been determined, and the happy applica- tion which M. de la Place had made of them to the production of inflammable gas by the dissolution of metals, threw great light on the whole of chemistry; phlo- giston, that principle which Stahl had ingeniously imagined in order to account for a large number of phenomena, and by means of which there was really established between them a connection which has served for a long time to guide chemists in their researches, appeared to me to have at last become a useless hypothesis, whereupon I believed it incumbent on me to subject dephlogisticated marine acid to new experiments, as its properties might destroy or confirm the opinion I had adopted. These experiments were the subject of a memoir which I read at the public meeting of 6th April 1785. I shall now enter into greater detail, add some new observations, and reply to some objections which have since then been made to the theory which I had established. Scheele, when investigating the effects which different acids produced on manganese, observed that muriatic acid produced an effervescence with it, and that there ‘[Translated from “Memoires de l’Academie Roy ah ” for the year 1785.
