Camphor is a concrète eflential cil, obtained, by fublimation, from a fpecies of laurus which grovvs in China and Japan. By diftilling nitric acid eight times from camphor, Mr Kofegarten converted it into an acid analogous to the oxa- lic ; but, as it differs from that acid in fome circumftances, we hâve thought neceflary to give it a particular name, till its nature be more com- pletely afcertained by farther experiment. As camphor is a carbono-hydrous or hydro- carbonous radical, it is eafily conceived, that, by oxygénation, it Ihould form oxalic, malic, and feveral other vegetable acids : This conjec- ture is rendered not improbable by the experi- ments of Mr Kofegarten ; and the principal phenomena exhibited in the combinations of camphoric acid vvith the falifiable bafes, being very * Thefe combinations, which were ail unknovvn to the old chemifts, are called Camphorats.
