the milk of a tuberculous cow. Experiments of Klebs have 

 proved that the contagion is not destroyed by the ordinary boiling 

 of the milk. Ballinger has lately corroborated these observations. 

 The milk of tuberculous animals is said to be thicker than 

 ordinary railk. The reaction is alkaline. The cream rises quickly. 

 Cream and milk are apt to putrefy in a short time. The milk is 

 not easily curdled by rennet or by heating. 



Anthrax : Milk of cows sick with anthrax is said to become 

 stringy, and in this state it breaks easily. Infected milk should 

 not be used. It is said that cattle are predisposed to this disease 

 when fed on distillery swill or the refuse of starch and beet-sugar 

 factories. 



Aphtha epizootica : Anaker says : " In some cases of aphtha 

 " epizootica (hoof and mouth disease), especially when the mucous 

 " membranes of the lacteal ducts are affected, or when the contents 

 " of the bladder find their way into the milk during the milking, 

 " the milk appears thicker, phlegmy, more yellow, lumpy, and 

 " blood-streaked. It emits a putrid odor, and possesses a repug- 

 " nant taste. Such railk will part, on standing, into a yellow se- 

 " rum, and a sediment which contains pus corpuscles and finely 

 " granulated masses in a state of dissolution. Such admixtures 

 " increase the specific gravity of such milk, while the percentage 

 " of fat, casein, and sugar are diminished. 



" The amount of salts is increased. The reaction of the milk 

 " is acid when the disease is at its height. It, therefore, curdles 

 " easy when heated to boiling. The cream yields often no butter . 

 " but butter made from such milk shows an iinnatural yellow color. 

 " "Whether such milk will prove injurious to the health of con- 

 '' sumers, depends upon the nature of the abnormal constituents. 



" Boiling does not always remedy the injurious properties of 

 " such milk. The use of such milk has been the cause of the fol- 

 " lowing symptoms : fever, blisters on the mouth and feet and the
