Chap. II. The Anatomy of a Horfe. i$ 



other than an Expanfion of the Ureters, which are two 

 Canulas, or Pipes, from which the Urine pall'es from their 

 reipedlive Kidneys to the Bladder. 



The Ureters keep not a ftreight Courfe The Ureters, 

 from the Kidneys, but in form of the Letter 

 / 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 Sphindter, or Neck. 



The "Bladder is feated in the lower part of "the Bladder, 

 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 Peritonaum^ the middlemoft muf- 

 cular, the innermoft very thin, and of an exquifite Senfe ; 

 having Nerves both from the Intercoftals, and the Verte- 

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

 the Hypogaftricks, The Bladder is perforated^ or bored, 

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

 Neck, to give Paflage to the Urine which runs along the Ure- 

 thra or Pifs-pipe, in order to its Difcharge out of the Body : 

 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 moft external of all The Tard, 

 the Parts adminiftring to Generation, I 

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

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

 flefhy Pannicle, which are tied by an Appendage called 

 the Franum^ or Bridle, which runs along the under Side, 

 in a narrow Slip, almoll 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.
