We should acknowledge the justice of these observations, and thank M. Pelletan for having substituted an accurate and rational proceeding for blind and thoughtless practices. The operation, nevertheless, as proposed by the professor, still exacts numerous mutilations. The inconvenience and inutility of so many efforts to preserve the body of our own kind, was, besides, long experienced by many spirited writers; which is proved by the eagerness with which they took advantage of the discoveries of Chaussier, respecting the properties of corrosive sublimate applied to embalming. By his researches it was proved, that this salt preserved animal matters soaked in its aqueous solution; that it produced this effect by an intimate combination with animal matter; in fine, that this matter saturated with corrosive sublimate, passed so quickly into a state of desiccation, that it was necessary to moderate it, to prevent the horny hardening of the soft parts. Parts thus prepared, are rigid, hard, grayish, and preserved at the same time from putrefaction and insects. No time was lost to profit by this property of the deuto-chloride of mercury, to apply it to the preservation of whole bodies. It was, in fine, the last method of embalming practised previously to my own, and held as very superior to that of the ancients. We shall collect here, some observations cited as remarkable examples, and as proofs of the excellence of the process. It will remain for us afterwards to appreciate its merits. Let us first see the facts. _First fact, (A.) Preparation made by Beclard._
