This method being unfit for the pre- paration of the Prussic Acid to be employed as a medicine, need not be mentioned in this place. It will be sufficient to give, the formula employed by Vauquelin, and recently adopted by the faculty of medicine at Paris, in their Pharmacopoeia.* The prussic acid prepared according to Yauquelin's directions, or to those of Scheele, is a safe and valuable medicine in the hands of a cautious praclititioner. The formula will be found in another part of this paper. Having obtained the pure Prussic x4.cidfrom the Prussian blue, it was to be expected that an acute chemist, like Gay Lussac, would not be long in discovering its real nature. This has indeed been the case ; and we now know that it consists of a particular gaseous and highly * Codex Medicamentarius, sive Pharmacopoeia Gallica, jussu Regis optiml editus a Facultate Medica Parisiensi, anno 1818,](https://iiif.wellcomecollection.org/image/b21055014_0017.jp2/full/800%2C/0/default.jpg)
