produces the animal fluids, as blood, bile, semen, and the rest; whicli Can never be produced by the art of chemistry. But is, in consequence of death, the Iaws of vitalattraction or assinit ' cease to operate, then theelemenis, recovering their former properties, become again obedient to the common laws of chemicat asinit , and enter into nexu combinations, from which ne N principies, or the pro duas of putrefaction are produced. Thus the hydrogene, combining itself with the a Zote, fornas volatile at ali: and the carbonated hydrogene, with the agote, jutrid cir; into Whichthe whole body is converted. It also appears from hence, Why organiZed bodies alone, namely, animal and Vegetabie, aresul edt to putridity ; to Whicli inorganic orminerat substances are, in no degree, liable ;the lalter not being compotanded according to the laws of vital assinity, but only according to iliose of chemicat assinity.

Frona what has hilherio been said, it will also appear, that the true constituent principies of an animal body cannot be detected, cither by putrefaction or the actiosi offre ; for by thesemeans, We only discoVer the elements of thos principies.
