![j&otir flies off into the air, of a moll offettfive ime!].— This bears no relemblance to the fmell of volatile a ka- line fairs.—Thefe revive • that produces almoft a de¬ lixivium animi.—This vapour aCts upon other bodies as a putrefactive ferment.—Even in heaps of fucculent vegetables, beginning to putrefy, if this vapour be diiperled, and the plants are properly aired or venti- lated, the progrefs of their putrefaction will be en- tirely flopt. Moillure and heat are both abfolutely neceffary for the promoting of putrefaction in all bo¬ dies. Putrefcence, in refpeCt of its fpreading multi¬ plicative power, is very juftly ftippofed analogous, in its operation, to ferments ; which diffufe their aCtion very wide, excite inteftine motion, and aflimilate into their own nature and properties, bodies which are fufceptible of this operation *. RefpeCting its aCtion upon the circulating fluids of living animals, putrefaction has been compared to Volatile alkaline ialts,—'and the rather, as putrid fub- fiances, chemically treated, are found to abound with Volatile alkalies.—Thele falts melt down the blood globules, and prevent coagulation when it is extra- Irafated. Putrefcence produces the fame effect, but in !l tnuch higher degree, on account of its multiplica- :ive property as a ferment: In this it greatly differs Tom alcaline falts; which, in faCt, are found capable >f preventing the putrefaction of animal fubftances f.
