Describe the mammary glands of the mare. 



The mammary glands of the mare are two hemispherical-shaped 

 bodies, lying together on the median line in the posterior and in- 

 ferior abdominal region, in the position of the serotTim in the male. 

 They terminate below in a small prominence, the nipple, or teat, 

 which is traversed by several sinuses that communicate above with 

 the milk reservoir and open on their free extremity by two, three 

 or four canals. The gland is covered externally by a fibrous coat 

 which sends prolongations into its interior and over this coat is the 

 skin. The body of the gland proper is made up of a highly devel- 

 oped type of sebaceous glands.
