The Second end of the Motion of the Blood, is in order to the generation of nervous Liquor, and animal Spirits in the Cortex of the Brain. . Tubes of Arteries and Veins, aéted by various flefhy Fibres, as f0 many Machines, lellening the greater and fmaller Cavities of the Heart, and different Sangtiidiifls, whereby the refifiance of the Blood is countermanded by a firong Comptellion, and its Flux and Reflux are maintained to and from the Heart, to impart Life, Heat and Nourilhment to all parts of the Body. The Motion of the Blood, being a great infirument of the prefervation of Humane Nature is conligned to many ends. The produc‘tion of Blood, the generation of nervous Liquor and animal Spirits; the depu. ration of the Blood in various parts of the Body, and the formation of feminal Liquor in the Tefticles. ' "(mint-"d The Firl't and main end of the Motion of the Blood, is Sanguification, gggmfgfi which is produced by Chyle allimilated into Blood, as tnore and more mix~ zj‘fginsu‘m' ed with it in theHeart, Lungs, Arteries, and Veins.

The Third end of the Motion of the Blood is its refinement from its Re- crements, in its palfage through the Interl'rices of the Veifels or Glands, lodged in the lVIiilcles, Vifcer‘a, and ‘Cutir.
