other than an Expanfion of the Ureters, which are two 

 -Canulas^ or Pipes, from which the Urine paffes from their 

 relpedive Kidneys to the Bladder. 



The Ureters keep not a ftreight Courfe ^e Ureters, 

 from the Kidneys, but in form of the Letter 

 /i they enter into the Back and lower Part of the Bladder, 

 where pafling about an Inch between its Membranes, to 

 prevent the Return of the Urine back the fame Way, they 

 are inferted near its Sphind^er, or Neck. 



The 'Bladder is feated in the lower part of The BlaJdf. 

 the Belly, within that Circumference which 

 is made by the Loins, Hip-bones, and Share-bone. It is 

 of an irregular Shape, fomewhat refembling a Pear, com- 

 pofed, as the Stomach and Guts, of a treble Coat or Skin, 

 the outermoft from the Perhonaum^ the middlemoft muf- 

 cular, theinnermoil very thin, and of an exquifite Senfe ; 

 having Nerves both from the Intercoftalj, and the Verte- 

 bra of the Loins. Its Veins and Arteries are Branches of 

 the Hypogaftruh. The Bladder is perforated, or bored, 

 not only where the Ureters enter into it, but alfo in its 

 Neck, to give Paflageto the Urine which runs along the Vre- 

 thm or Pifs-pipe, in order to its Difcharge out of the Body t 

 Its Neck is compos'd of mufcular and flefhy Fibres, which 

 form a Sphinder Mufcle, fuch as has been defcrib'd belong- 

 ing to the Fundament, which opens and fhuts at Pleafure.

§.V1. Of the Parts of Generation in a Horfe and Mare, 



The Tard being the moll external of all The Yard^ 

 the Parts adminiftring to Generation, I 

 fhall therefore begin with it. Its outer Cover, or Sheath, 

 is nothing elfe but a Production of the Scarfskin, Hide, and 

 flefliy Pannicle, which are tied by an Appendage called 

 the Franumy or Bridle, which runs along the under Side, 

 in a narrow Slip, almoft to the Root of the Yard ; fo 

 that the Sheath folds back in feveral Wrinkles, and 

 gives full Liberty to the Yard, as often as it is extended 

 and drawn.
