squarely placed. Prof. Plumb puts the question "may 

 not a material gain in milk-flow be secured by develop- 

 ing the foreudder!" The figures submitted by him in 

 Bulletin 62, of Purdue University, certainly hold out 

 testimony that such improvement may result. 



In heavy milkers the udder is often perpendicular; 

 what is termed the funnel-shaped udder is not a desirable 

 type, neither are udders with very large teats. It is 

 interesting to note 

 that no such irregu- 

 larity of form is pre- 

 sented by any part of 

 the anatomy of the 

 horse, ox, sheep or 

 pig, as shown in the 

 milk, glands of the 

 cow. If one- quarter 

 of an udder is dis- 

 eased, the other 

 quarters do not seem 

 to take on the work 

 of the resting quarter. 



The function of the 

 udder is to secrete milk, the stimulus to do so being the 

 maternal function, thus the work of this organ differs 

 from that of others in the body, in that its secretion 

 serves no useful purpose tp the animal secreting, but is 

 intended to serve as a food on which to raise the offspring. 



The secretion of milk is held to depend on a throwing 

 off of the epithelial cells of the alveoli, combined with a 

 filtering out of water, salts and other materials from the
