 of which are through these two teats. In the upper part of each of the teals is a small 

 milk cistern. On the opposite side of the udder is a second gland having outlets through 

 the two right teats. Out of the blood brought to the udder through the arteries, th<: 

 cells next to the glands are formed. These cells are gradually changed into milk, which 

 fills the glands and the milk cisterns, and passes off through the nipple of the teats.
