MILK IN DISEASES. 671 



may also pass into the milk, but probably not in such quantities as to 

 have any direct action on the nursing child. 1 Alcohol is claimed to have 

 been detected in the milk after feeding cows with brewer's grains. 



Among inorganic bodies, iodine, arsenic, bismuth, antimony, zinc, 

 lead, mercury, and iron have been found in milk. In icterus neither 

 bile-acids nor bile-pigments pass into the milk. 



Under diseased conditions no constant change has been found in woman's 

 milk. In isolated cases SCHLOSSBERGER, JOLY and FILHOL 2 have indeed observed 

 a markedly abnormal composition, but no positive conclusion can be derived 

 therefrom. 



The changes in cow's milk in disease have been little studied. In tuber- 

 culosis of the udder, STORCH 3 found tubercle bacilli in the milk, and he also noted 

 that the milk became more and more diluted, during the disease, with a serous 

 liquid similar to blood-serum, so that that the glands finally, instead of yielding 

 milk, gave only blood-serum or a serous fluid. HUSSON 4 found that milk from 

 murrain cows contained more proteins but considerably less fat and (in severe 

 cases) less sugar than normal milk. 



The milk may be blue or red in color, due to the development of micro-organisms. 



The formation of concrements in the exit-passages of the cow's udder is often 

 observed. These consist chiefly of calcium carbonate, or of carbonate and phos- 

 phate with only a small amount of organic substances.
