JTREVIOUS to commencing the chemical hiftory of the fubjecT: of thefe pages, I muft apologize for the aflumption of the new term by which I have defignated it: this is the more necefTary, as a diverfity of terms, expreffive of the fame idea, may be faid to retard the advancement of knowledge; and efpecially as the inno- vation of an unexperienced Student may have the appear- ance of boldnefs or prefumption: yet the reafonablenefs and propriety of the thing itfelf, it is hoped, will amply warrant the adoption. It is well known, that the com- binations afforded by nitre have been hitherto considered as of mineral origin, and that the terms azote, azotic, nitrous, nitric, &c.* were adopted by the French Aca- demicians -, and as the firft of thefe and its derivatives were exceptionable; the term nitrogene had been fubfti- tuted for it by fome of the later writers:-]- but, from the evidence of the moft Striking fads, we mall, in the fequel, be able to prove, that the nitrous acid, forming a part of the fait nitre, is of animal derivation^ formed from azote and oxygene, during the putrefaction of fubftances of that kind j and that by the addition of the vegetable * See Table of Chemical Nomenclature, by Lavoifier, &c. for 1787, title Azote. f Chaptal's Chemiftry, paflim—Pearfon's Transition of the Nomencla- ture.
