The Introduction. 



H E Bodies of all ^Ijiadrupeds^ as ivell as 

 Men, are compofed of different Parts, which 

 arc adapted to their fever al Fun£iions : Some 

 are folid, as the Bones and Cartilages ; others 

 are foft, as jf/)^ Glands andMxiJizxxhx Flejh^ 

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

 Joints, and Tendons of the Mufcles. But ivhether their 

 particular Struuure be loofe or folid, or bet'jceen both, it 

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

 Threads. This is fo plainly ohfervable in the f oft Parts^ 

 that it needs no manner of Proof-, fince every one mufl hav-e 

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

 cf little Parcels or Bundles^ and thefe Parcels w.ay again, 

 be divided into othsrs which are lejs, and afternicards into 

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

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

 ture of the hard Parts ; for when ive cut a Bone acrofs, all' 

 the Poruli, or little Holes, iv-hich form the hiterfiices of its 

 Fibres, are, in mofi Parts of it, plainly perceivable ; and 

 if it be cut lengthways, their Dire^ion and Courfe is no 

 lefs manifefl. 



But of all the different Subflances zohereof en Animal 

 Body is compofed, that which Anatomijis call a Mem- 

 brane, is, next to a Fibre, the mofi f.mpk in its Stuc-
