: they tin n unite at the mesial line, below the anal opening, thus 

 I'' >rining around the terminal extremity of the rectum a real suspensory ring. 

 Lyino; together, ami intimately united, they are continued on the accelerator, 

 which they follow at the raphe, and are eventually lost in its texture near 

 tin- I'm- extremity of the penis. 



These cords are composed of unstriped muscular fibres. 

 B. SHEATH (prepuce). The sheath is a cavity formed by a fold of the 

 abdominal integument, and lodges the free portion of the penis; it is 

 entirely effaced at the moment of erection, when the copulatory organ is 

 thened and enlarged. The skin at the opening of the sheath enters its 

 cavity, and, on arriving at the free portion of the penis, forms a circular 

 <-l-<1c. sac in becoming reflected over the organ, which it envelops. 



This lining integument of the sheath is fine, and very irregularly 

 t- d : it is destitute of hair, and holds a middle place, with regard to 

 organisation, between the skin and mucous membranes. It contains in, or 

 beneath, its substance a considerable number of sebaceous or prceputial glands 

 that secrete an unctuous fatty matter (exhaling a pecular odour, and dark- 

 grey in colour, the gmegrna prceputii), which is spread over the surface of 

 the membrane. 



Above, the inner integument of the sheath is applied to the fibrous tunic 

 of the abdomen. Below, and on each side, the cutaneous fold constituting 

 this cavity contains between its layers an expansion of yellow elastic fibrous- 

 tissue, the lateral portions of which, attached to the abdominal tunic, are 

 named the suspensory ligaments of the sheath. 



In the Ass, there exists, near the entrance to the sheath, and on each side, 

 a small tubercle which may be looked upon as a rudimentary teat of the 

 female. 



(The prepuce protects the penis, and sustains it when in a flaccid state. 

 In o-rtain Horses, a gurgling sound is produced in trotting, from the air 

 entering and leaving the sheath suddenly.)
