The infpired Air is profitable to Smelling,Tafling and to the local motion, Fermentarion,and mixture of the Blood with the Chyme ', as alfo to the motion of the Chyle and Lympha. The Expired Air is conducive to Speech, Voice, Coughing, Sneezing,and Spitting; and the Air being detained in the Lungs, doth promote the excre- tion of Urine and grofTer Excremcnts, and alfo facilitates the Birth of Children. . of: of The Antients have conceived the ufe of Refpiration was only to cool the The Refpiration is to cool the Blood, but if we well confider how Nature is fupported in its vital flame of l Life, we {hall find the Blood, (by which it is maintained) to have a greater Bl need of Heat then Coolnefs, to make good its local Motion, and Fermen- ration. Hippocrater, the Great Mal'ter of our Art, did attribute a neceHity to Refpiration, in reference to conferve Life; laying, that we can live fome time without the entertainment of Aliment, but we cannot continue our Life many moments, without conf'tant Draughts ofAir, immitted freely into its greater and leis Tubes, to (pin out the thread of Life, by frequent repeated the thinnefs of itan evident Experiment is given by the (aid ExperimenIOf the molt Ingenious Author, in which the molt part of the Air being exhaufied out of hn Air-pump, {0 that almofi nothing but Ether remained, as (ll- lation of the vital Liquor.
