The Anatomy of a HORSE.' 107 



ilvhich Farriers fomctimes open in Fevers, ^V. the Plate- 

 veins, the Shank- veins, and Shackle- veins, as alfo the 

 Veins of the Cornet and Toe, which are ufually opened in 

 Difeafes of the Legs and Feet. 



The Cava afcendens, or the great afcend- cjj^^ afcendinz 

 ingVein, which anfwers to the great de- Qava. 

 fccnding Artery, receives alfo all thofe 

 Branches of Veins which return the Bloody from moffi 

 Parts of the Lower Belly, vi%. the Mejenteria from the 

 Mefentery, the Portce from the Liver, the Emulgents 

 from the Kidneys, the Spermatick Veins from the Parts 

 of (kneration in both Sexes. And after it divides itfelf, 

 as the Artery, into the internal and external Iliads^ it 

 receives feveral Branches. Into the Internal j^^ Diflribu- 

 open the Hypogaflricb, by which the Blood ^/^^^ 

 is returned from the Matrix, the Bladder, 

 and ftreight Gut ; and into the External open the Eptgaf- 

 iriciSy with Blood from the Peritonaiofiy and external 

 Parts of the Lower Belly ; and into the Epigajiricks open 

 tiie Criirdlsy which receive all the Blood that flows from 

 the extreme Parts ; for into them open thofe Veins, im- 

 jjroperly called by Farriers the Kidney-veins ; as alfo the 

 Spavin-veinSy the Flank and Spur-veifHy with that of the 

 Kump, C3.1!ed the Talc-vein. 



Thcfe Things being premifed, it will be eafy for any one 

 to form an Idea of the Diftribution of the Blood into all 

 Paris of the Body ; efpecially if it be far- n-i -kt . •.• 

 ther conlidered, that the Veliels m which of the Parts 

 tlie Blood flows, are divided and fubdivided 

 into an intinite Number of Branches ; and that even all 

 the Parts of the Body, whether thofe that are hard, or 

 thofe tiiat are denominated foft Parts, feem to be no other 

 than fo many infinitely fmall Tubes varioufly modified 

 and combined together ; for by this Means the whole Body 

 is filled with Blood and other nutritious Juices, and re- 

 ceives its Nourifliment from Blood, as the Blood itfelf is 

 recruited and repaired by the Aliment. And from the 

 llime Confideration it is alfo evident, that no Animal 

 Body can be furtained without the Requifites of Food and 

 Rett, by Reafon the Strufture of all Animal Bodies is of 

 this Sort ; that is to fay, all are made up of Fibres, and 

 thffe Fibres are again made up of thofe that are lefs, and 

 jfoon in ififinitum. They muft therefore, becaufe of the 

 [Inliaity of Pores and Inteflincs that arc in them, require 

 I conltant
