ANATOMY 



O F A 



HORSE. 



The Introdudiion. 



H E Bodies of all ^adrupeds^ as well as 

 Me72y are cetnpofed of different Parts, which 

 me adapted to their feveral Fun^ions : Somi 

 are fo lid, as the Bones and Cartilages ; others 

 are foft, as the Glands and Mufeular Flejh^ 

 and feme are of a middle Nature, as the Ligaments of the 

 Joints, and Tendons of the Mufcles, But whether their 

 particular Stru^iire be loofe or folid, or bet-ween both, it 

 is very certain that all are made up of fmall Fibres or 

 Threads. This is fo plainly ohfei-vable in the f oft Parts^ 

 that it needs no manner of Proof-, fince every one muft have 

 taken notice, in tearing Flejh afunder, that it is composed 

 cf little Parcels or Bundles^ and thefe Parcels may again 

 be divided into others which are lefs, and afterixards int& 

 ftngle Threads, which are infinitely [mailer than a Hair : 

 Nature has alfo obferv'd the fame Oeconomy in the Struc" 

 tare of the hard Parts ; for when Ttv cut a Bone acrofs, all 

 the Poruli, or little Holes, which form the Interflices of its 

 Fibres, are, in mofl Parts of it, plainly perceivable ; ani 

 if it he cut lengthways^ their Dire^ion and Courfe is m 

 lefs manifefl. 



But of all the different Suhjfances whereof an Animal 

 Body is compofed, that which Anatomifs call a Mem- 

 brane, is^ next to a Fibre, the mofl fmpU in its Stuc^
