Tuberculosis. 497 



with tuberculosis of the udder possesses a virulence which can 

 only be described as extraordinary. All animals inoculated 

 showed tuberculosis in its most rapid form." Woodhead is 

 equally positive in this position. Galtier says " we should abso- 

 lutely avoid the consumption of milk from cows in which the 

 udder is tuberculous, and boil before using, the milk of all 

 cows affected with, or suspected of tuberculosis in any form." 

 Finally we should never consume without boiling, milk of which 

 we do not certainly know the origin, and especially in cities, we 

 ought not to omit this precaution in the case of milk furnished 

 by milkmen." Rabinowitsch and Kemper add : " Milk from 

 cows that react to tuberculin must be suspected of being tuber- 

 culous in every case." 



It may well be allowed that the mixed milk from a large dairy, 

 containing but one or two tuberculous cows, is much less infecting 

 than that of the tubercular cow herself, and that skim milk that 

 has been passed through the separator has been robbed of many 

 bacilli which have been precipitated in the albuminoid material 

 that collects on the inner side of the bowl. But these mean dilu- 

 tion not purification : they reduce the danger but do not altogether 

 remove it, and sanitary police should aim at sterilization in every 

 case where available. 



Butter, cheese, whey, and other dairy products have been proved 

 virulent in different cases (Galtier, Heim, Lasar, Bang, Ober- 

 miiller, Roth, Groening, Gasperimi, Petri, Rabinowitsch). This 

 was true for butter 120 days old, and cheese 330 days. In a 

 number of cases Rabinowitsch found a bacillus, similar to the 

 tubercle bacillus and producing tubercle-like lesions, but differing 

 in its staining, morphology and culture, and she supposed that 

 other observers had mistaken this for the tubercle bacillus. Petri, 

 Morgenroth and Hormann, found the bacillus of Rabinowitsch in 

 company with the real tubercle bacillus in butter, and Rabino- 

 witsch, later, in fifteen samples of butter found the bacillus tuber- 

 culosis in two. 



Bacilli coming from the mouth, bowels, or lungs, are also liable 

 to get into the milk, through the floating dust of the stable, or 

 from the teats, udder, tail, etc., (Gaffky). 



Oleomargarin cannot be considered as free from this indictment, 

 for though the tuberculous glands, etc., from the mesentery, may
