hold it in place. This fibrous partition is attached to the abdomen 

 in front and to a point between the thighs in the rear. There is 

 no passage of the milk from one gland to another on each side of 

 this partition, but there is some passage of milk from one teat- to 

 another on the same gland. This may be shown by milking dry 

 the two teats on each side of the cow or those on the same gland 

 when approximately the same amount of milk will be obtained 

 from each pair of teats. If the two fore teats or the two hind teats 

 which are each on different glands are milked dry it will be found 

 that the weight of milk obtained from each of these pairs will be 

 influenced by the order in which they are milked as the milk of 

 each teat of a pair in this case comes from a separate gland. If. 

 however, the milk from each teat on one side or on the same gland 

 is weighed it will be found that the most milk will be obtained from 

 the teat milked first, showing that there is some communication
