After the purer part of the Chyle hath been thus strained thro’ the narrow and oblique Pores of the milky Veins, by the continual and peristaltic Motion of the Intestines, it is yet farther attenuated and diluted with a very thin and clear _Lympha_ from the Glands of the Mesentery to expedite its passage thro’ those numerous Meanders into the common Receptacle, from whence by the constant Supply of such like _Lympha_ from the small Glands of the _Thorax_, it is safely conveyed thro’ the _Ductus Chyliferus Thoracius_, subclavian Vein, and the _Vena Cava_ into the Heart. The Chyle now mingled with the Blood, passeth with it thro’ the Arteries of the whole Body, and returns again with the Blood by the Veins to the Heart, undergoing many Circulations before it can be assimilated to the Blood; for every time the new infused Chyle passeth thro’ the Heart with the Blood, the Particles of the one are more intimately mixed with those of the other, in it’s Ventricles, and the Vital Spirit, and other active Principles of the Blood work upon the Chyle, which being full of Salt, Sulphur and Spirit, as soon as it’s _Compages_ is loosned by it’s Fermentation with the Blood, the Principles having obtained the Liberty of Motion, do readily associate themselves, and are assimilated with such parts of the Blood as are of a like and suitable Nature. After the Chyle hath been thus elaborated, it becomes fit as well to recruit the Mass of Blood, as to nourish the whole Body, seeing it consists of divers Principles and Parts of a different Nature; therefore, according to the various Use and Necessity of every part, and also that it may conform and fashion it self to the different Pores and Passages, it is severally appropriated; the most volatile and subtil part is separated in the Brain, and adapted to refresh the Animal Spirits, the glutinous to nourish the Body, and the sulphureous to revive the native Heat: And in it’s Passage with the Blood thro’ all the parts of the Body, all the Mass of Chyle that is capable of being turned into Blood is sanguified; the serous and saline part precipitated by the Kidneys, and evacuated by Sweats or insensible Transpirations, the bilious is deposited in the Liver, and the rest of its Excrements retire to the several Emunctories of the Body.
