Chap. II. The Anatomy of a HORSE. 19 



Rugcs and Caruncles ; the Ule of which are to llimuiate 

 the Horfe to a vigorous Difcharge of his Seed. Befides 

 thefe, there are the Nympha juft within the Lahia^ and 

 the Clitoris more backward, which not only ferve to the 

 faipe 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 Senfatiori. The inlide of that Pallage has a thin 

 Mucus from its Glands, which is not only a Defence to ir^ 

 but like wife 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 the 

 Lips, on the upperfide, 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 Sphinifter to 

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

 NymphiZ do the fame Office in the Vagina : And when 

 they are contradted, or rather clofed together, from the Fif- 

 fure, 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 <^^^ Udder 

 Mare, being that from whence the Foal re- 

 ceives its firft Nourifhment after its Birth. Its Subllance 

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

 Milk is feparated from the Blood, which is brought into 

 it by the Hypogaftrick Arteries, and carried along in little 

 Pipes to two GlandS) which are pretty large, feared at the 

 Root of each Pap, where undergoing its laft Refinement^ 

 it is difcharged firll into its proper Veficles/ and then into 

 the Paps which convey it to the Foal. 

 ■^ The' the Udder of a Mare feems to be one undivided 

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

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

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

 Mare fliould have one Side of her Udder hurt, the Foai 

 may dill be nourifhed by the other. 



It mayj perhaps, be expelled that I fhculd 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^ 

 li^hich by moll modern Anatortiifts is believed to be full of 

 Aniinalcula^ or little moving Creatures, which, they fay, 

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

 that Liquor, But as thefs Things would not only be too te-
