fore it empties itfelf into the Jutide ; and they are 

 accompanied by two Arteries, from the Aorta or 

 great Artery, which run thro' all the Subilance of 

 the Heart ; they are called the Coronary VeiTels. 

 The Arteries bring the Blood for Nutrition and Mo- 

 tion of the Heart, and the Veins carry back what 

 is fuperabundant. The Branches of the Veins on 

 the right Side communicate with thofe of the left ; 

 and in like Manner do the Arteries on each Side 

 communicate with one another ; and it is the farrie, 

 tho' not every where fo evident, in all the Parts of 

 the Body. 



The Heirt leccives a Multitude of fmall Nerves 

 from the Eighth Pair ( as they are called by Ana- 

 tomies ; ) particularly they creep in great Numbers 

 about the Aorta and the left Ventricle. It has alfo 

 feme Lymphaticks or VelTels which convey a thin 

 Liquor which dilcharge themfelves into the Lym- 

 phatic Duel or Pipe. 

 The A\iri- At the Bafis of the Heart there are two Auricles 

 cks dc- or little Ears, one on the right, the other on the left 

 llribed. gjj^ . Y\\x,q the right Ear opens the Vena Ca'va, into 

 the left xhtV ena P uhnonalis : The firft difcharges the 

 Blood it receives from the Ca^a into the right Ven- 

 tricle, and the fecond thrufts the Blood which comes 

 from the Ve^ia Pulmonalis into the left Ventricle. 



The left Auricle is lefs but thicker than the right ; 

 their Subilance is compofed of two Orders of Muf- 

 cular Fibres, which terminate in a Tendon or finewy 

 Subilance. At the Bafis of the Heart, and at the 

 right Ear, there is a Circle like to a Tendon where 

 the Canja ends. 



Their external Surface is fmooth, their internal 

 is unequal, Eill of fmall flelhy Pillar?, which fend 

 out fmall Fibres that crofs and go thwart one ano- 

 ther, and betwixt thefe Pillars, there are as many 

 Furrows. They receive Nerves from the Branches 

 of the Eighth Pair. They have the fame Motions 

 as the Syftole and Diajiole of the Heart, that is to 

 fay, they dilate and contrail m the fame Manner.
