selves close together into mutual embraces: Whence he goes on to shew That the whole Motion of the Heart consists indeed in the Systole, that of the Diastole being onely a Motion of Restitution. Further, that there is a necessary Commerce betwixt the Heart and Brain (the Cause of all Sense and Motion:) but that both ultimately depend from the Stomack, as the constant Purveyor and Furnisher of Matter for Bloud and Spirits.
In the Third Chapt. he teacheth, with what Celerity all the Bloud passeth through the Heart, and what difference there is between the Venal Bloud and the Arterial. As to the former, he calculateth, that all the Bloud passeth through the Body, thirteen times, (not Six, as 'tis misprinted in the Book it self) in one hour. And concerning the latter, he is of opinion, that the Purpureous and florid color of the Blood in the Arteries proceeds not from its Accension in the Heart (if there he any such thing) but depends altogether from the Lungs, and the Admixture of the Air with the Bloud there: which he proveth by considerable Experiments; refuting withal the opinion of those that will derive it from the Comminution of the Bloud in the Lungs.
In the Fourth Chapt. he gives an Accompt of the Rise, Progress and Use of the Invention of Transfusing Bloud cut of one Animal into another: though in the History of this particular he commits (I know not by what over-sight) a mistake, in relating, that Monsieur Denys (call'd by him Dionysius) arrogateth to himself that Invention, whereas he onely tells us that some of his Nation do so. Besides which, we must needs take notice of another mistake in this part of the Book, viz. that the Author taking occasion to speak of the Philos. Transactions calls them the Transactions of the Society; which certainly he would not have done, if he had either but taken notice of what is said in Numb. 11. of the same; or else consider'd, that so Illustrious and so Learn'd a Body would certainly, if they thought fit to publish any thing as theirs, entertain the knowing World both with sublimer Mater, and with a sutable Eloquence: But this by the by.
In the Fifth Chapt. he treats of the Chyle, and its Change into Bloud; where he observeth, that nothing passes from the Spleen through the Vase breve into the stomack; but that the Ferment
