udder to a large size, caused by storing much milk, which 

 accounts for the moderate extent of circulation ; while much 

 of the udder surface is kept warm by the heat of the thighs, 

 etc. Neither the dandruff, nor the pale color of the udder 

 skin, has any influence or signification as to the quantity or 

 quality of milk-yield ; the blood supply of the skin, and 

 its discharged matters being derived from the general cir- 

 culation ; while the Milk Yield is formed from the breed- 

 ing blood, which is conveyed in separate and special blood- 

 vessels, that are adapted to supply the 'embryo during 

 pregnancy, and the udder after coloring.* 



Fineness in the hair and in the grain or fibrous structure 

 of the skin and flesh, indicate thrift and good digestion, 

 and the full completion of the various and successive 

 changes in the contents of the cells during the process of 

 assimilation ; fine grained, compact and firm muscular 

 structure, indicating much change in the crude ingredients 

 of the blood during their transformation, by thorough 

 assimilation into such structures as skin, hair and flesh. 

 The same quality of structure probably holds true in the 

 milk-gland muscles ; all these structures being formed from 

 the same quality of blood of the general circulation. But 

 the quality of these structures does not indicate the quali- 

 ty of the milk, this calf food depending more on the qual- 

 ity of the cow's food than on any other conditions or cir- 

 cumstances affecting it. 



The color of the skin may be yellowish from the oxida- 

 tion of oily matter in the surface layer. But this does not 

 affect the quality of the milk. 



Having considered the various marks and conditions 

 adverted to in Guenon's Treatise, including the trivial 

 tufts, ovals, and rudimentary teat marks; the dandruff and 

 the color of the udder, and the skin, as well as the more
