7*r ^..uii. .., The internal Subftancc of the Yard con- 



lilts or two nervous Bodies, which, as in 

 Man, make up the greateft Part of its Bulk. Thefe two 

 Bodies are very fpungy and open in a Horfe, and when 

 dried, are extremely light ; but in a Bullock, and fome 

 other Animals, they are more compad and folid. I'hey 

 are compofed of a vail many Branches of Veins, Arteries, 

 and Nerves, which are varioufly interwoven one with an- 

 other. On the underfide, between thcfe two cavernous 

 Bodies, runs the Urethra^ or Pifs-pipe, from the Sphin6ler 

 of the Bladder, to the Etxremity of the Glans or Nut, 

 which affords a Pallage both for the Urine and Seed. 



The Glans is an Appendage to the Yard ; it is of a 

 round Figure, but very thin, in proportion to what It is in 

 Maji ; it is not fo cavenous as the Yard, but of a quicker 

 Senfe, being the chief Seat of Pleafure in Copulation. 

 lis Mufdes T\\^ Yard has two Mufcles on each Side 



towards its Root: The iirll Pair fpring 

 from the external Proofs or Knob of the Hip-bone, and 

 held the Yard in Eredion ; the other two rife from the 

 Fundament, and are called the Dibiers, becaule they 

 ferve to open and widen it for the freer Pallage of the Seed 

 Its Feffels ^"^ Urine. Its Veins and Arteries fpring 



* from the Hypogajlncb^ and its Nerves from 



the lower Vertebral. 



The Stones 't>itxt to the Yard, the Tejies^ or Stones^ 



properly take place, becaule in them the 

 Seed is prepared : They are two glandular Bodies of an 

 oval figure, fituated under the Root of the Yard, hanging 

 in a Scrotum^ or Bag ; which is no other than a Produc- 

 tion or Continuation of the Sheath above defcribed. The 

 Stones have each a Branch from the /f;?-/.-;, or great Ar- 

 tery, which brings the Blood dire6lly from thence, not 

 only for their Nourifhment, but for Seed. 

 ITheir Ve/T I Their Veins are Branches of the Cava^ 



' fome of which open into the great Trunk 

 thereof, very ne«.r the Emulgents, but not in the Emulgenis, 

 as in Men. Thefe are called ihePrteparatoria, or prepar- 

 ing Veilels, from which the upperfide of the Stones are cu- 

 rioufly clafped and twined, like the Tendrils of Vines ; and 

 growing narrower, and uniting more together as they ad- 

 vance towards the Belly, they are denominated by fevcral 

 Names, as the Pyramidal Body, and Plexus Pampiniformisy 

 &c. On the backfide of each Stone there is a longilh Bo- 

 dy
