whuh are more hard and brittle ; and if they were not thus 

 fortified^ might theiefore be worn and abraded by their 

 Motion. 



The Bones are of the mcjl hard and compa^ Suhjlsnce cf 

 the whole Body ; they are zvithout Senfey as are alfo the 

 Ligaments and Cartilages, otherivife they ivouid be unfit to 

 anfiver their particular Fun^ions ; buty tiothwith (landing 

 their hifcnfibilityy if any oj them happen to be difeafedy they 

 may caufe Pain, and create a great deal of Trouble. 



As the Bones argy of ail the Parts rxhich compofe an 

 animal Body, the mofl folidy the Ghnds, or Kernels, are 

 reckoned among the Joftejl \ being curious Bundles off^ejjelsy 

 'vchich are infinitely fmally and laid clofely together^ in many 

 Circumvolutions and Turnings : From feme of thefe are Je^ 

 parated ExcrementSy and from others Juices^ which have 

 their peculiar U/eSy as will bejhewn hereafter. 



The Veins, and Arteries, Nerves, tf/zi Lymphatick Veffelsy 

 are the Conduits and PipeSy through which all the liquid 

 fuices of the Body do pafs. The Arteries are Vcjfels luhicb-- 

 carry the Blood from the Heart to the ExtremitieSy and the 

 Veins are the Channels ivhich carry back that Portion of it 

 which is more than fufjicient for the NouriJ})ment cf the 

 particular 'Members. The Nerves are of a compaSt Sub- 

 llancBi, like fo many tough Cords, of a white Colour, and 

 different Sizes, fome being pretty large , others infinitely 

 [mall -y and tho* they fetm tobefolid and imperforate, that 

 is to fay, without any vijible Bore or Cavity in them, yet 

 it is very certain they carry the animal Spirits from the 

 'Brain into all Parts of the Body ; and are the Injiruments 

 which communicate all Senfjiiom to the Iriiagination. The 

 Lymphatick Veffels are of a more thin Texture y and carry 

 a clear tranfparent Liquor, which is alfo /ubfervient to the 

 Funifions oJ' Nature. 



InJ})ort, all the Parts of the Body, whether thofe that 

 are hard, or thofe which are denominated foft Parts, are 

 tmirijl^ed by Blood, and their peculiar Juices produced of 

 Blood: Neither is it improbable, that the whole animal 

 Frame is compofed of the jeveral Modifications of Veins, At- 

 teries. Nerves, and Lymphatick Vefjels. 



Thefe Things being premifed, for the Benefit of fuch as 

 are Strangers to the Study of Anatoriy ; I fioall now pro- 

 ceed to handle the Subject particularly y and take every Part 

 ss it lies in its pn>per Order,
