Chap. II. The Anatomy of a HORSE. Y^ 



Rugce and Caruncles ; the Uft of which are to ftimulate 

 the Horfe to a vigorous Difcharge of his Seed. Befidea 

 thefe, there are the Nympha jufl within the Labia^ aind 

 the Clitoris more backward, which not only ferve to the 

 fame Purpofe, but to augment the Pleafures of the Mare ; 

 the Clitoris being a fpongy Body, anfwering to the Glands 

 or Extremity of the Horfe's Yard, and endued with the 

 fame Senfation. The infide of that Paflage has a thin 

 Mmus from its Glands, which is not only a Defente to iiy 

 but likewife ferves to facilitate the Paflage of the Horfe's 

 Yard ; which being an extreme fenfible Part, would other- 

 wife be hurt by its unevennefs. About an Inch within th^ 

 Lips, on the ijpperfide, there is a fmall Paflage by which 

 the Urine is difcharged from the Bladder into the Extremi- 

 ty of the Sheath : And as the Bladder has its Sphinder to 

 fhut up its Neck when the Urine is drained from it, fo the 

 Nympha do the fame Office in the Vagina : And when 

 they are contrafted, or rather clofed together, from the Fip 

 Jure, or Chink, they are alfo of further ufe to prevent 

 Flies, Dirt, or any extraneous Matter from getting within it. 



The Udder is another Part peculiar to the <j^^ iJdJer 

 Mare, being that from whence the Foal re- 

 ceives its firfl: Nourifliment after its Birth. Its Subfl:ance 

 is partly fat, and partly glandular : By its Glands the 

 Milk is feparated from the Blood, which is brought into 

 it by the Hypogajirick Arteries, and carried along in little 

 Pipes to two Glands, which are pretty large, feated at the 

 Root of each Pap, where undergoing its laft Refinement, 

 it is difcharged firft into its proper Vefieles, and then into 

 the Paps which convey it to the Foal. 



Tho' the Udder of a Mare feems to be one undivided 

 Subftance, yet, as in all other Animals, it is truly fepa- 

 rated ; the Veflels of one Pap having no immediate Com- 

 munication with the Veflels of the other. So that if a 

 Mare (hould have one Side of her Udder hurt, the Foal 

 may ftill be nourifhed by the other. 



It may, perhaps, be expeded that I fliould put an End to 

 this Chapter, by giving fome Account of Conception, and 

 the Manner of the Foal's being nourifhed in the Womb ; and 

 likewife that I fhould take fome notice of the Male-Seed, 

 which by molt modern Anatorhifl:s is believed to be full of 

 A/iimalcula, or little moving Creatures, which, they fay, 

 by the help of a Microfcope, may be plainly difcerned in 

 that Liquor. But as thefe Things would not only be too te-
