![[ IO ] Let us compare thefe phenomena with thofe of animal heat, and notice the agree- ment between them. It will be firft afked where are, and of what confift, the combina- tion and decompofition ? Will it be thought fufficient if I fay, in the lungs, during refpira- tion, a part of the air is combined with the blood, and that in its turn fends off carbone* with the air expired. This procefs appears fimilar to combuftion, the fmoke of which is exactly fimilar to our breath expired ; the prefence of oxygen is nec- effary to the fupport of the one as well as the other, during both of which the calorict of the oxygen is feparated from the air; their refi- dues are totally unfit to fupport refpiration or combuftion, until they are again oxygenated. This, not being thoroughly underftood, ha* been treated as hypothetical.*^ Therefore * This is the coaly principle, the bafe of carbonic acid, + Matter of heat. % Cullcn'i Phyfiology.](https://iiif.wellcomecollection.org/image/b21155793_0014.jp2/full/800%2C/0/default.jpg)
