bunch of grapes. The bladder and the other urinary organs 
resemble those of the horse. 
V. THE GENITAL ORGANS OF THE COW. 
13. The Ovaries. 
The Ovaries of a cow are smaller than those of the marc, 
but resemble them in structure. 
14. The Womb. 
The Womb of the cow somewhat resembles that of the 
mare, but the inside lining is different, being covered with 
button-like procegtes about the size of a pigeon's egg, only 
more f?5tteried out. These processes receive the name of 
cotyledons; to these the cleaning or afterbirth is attached — 
a very important point with which every person interested 
should become familiar. These may be seen by examining 
the womb after calving or by opening a cow that dies soon 
after calving. The passage from the womb of the cow is 
shorter than that of the mare, but is formed on the same 
principle. 
15. The Mammary Glands or Bag. 
The Bag, mammary glands, or udder, is a very important 
organ of the cow. It is first divided into two halves by a 
partition or wall. Each half is again divided into two parts, 
each forming a quarter of the bag and each having a mam- 
mary or milk gland and a sinus or pouch in which to hold 
the milk secreted until the cow is milked. This sinus or 
pouch is situated just above the passage of the teat. 
VI. THE GENITAL ORGANS OF THE BULL. 
(a) The Testicles are ovoid in shape and well developed. 
(b) The spermatic cord and artery are small compared 
with those of the horse. 
(c) The penis is long and pointed, and has an S shaped 
curve in it just below the pubis, or hip bones; this curve can 
be felt by feeling carefully just behind the bag. 
(d) The sheath is long and runs further forw^ard on the 
belly. It has a tuft of hair on the point of it. During the 
time the bull is serving a cow the S shaped part of tlie penis 
straightens out.
