180 TUBERCULOSIS IN SWINE 
The older authors noted that the ancient scrofula was often accom- 
panied by visceral tuberculosis, but they refused to admit the identity 
or even the relationship of the two affections. 
The generalization of the disease, especially in the muscular tissue, 
is reported by several observers. Moulé called attention to this 
peculiarity of the disease. Stockman shows that while the disease 
is ordinarily generalized, muscular lesions may exist in swine in the

absence of generalization. Zschokke has called special attention to 
the localization of tuberculous lesions in the head of swine, especially 
in the nares and brain. 
Diagnosis. Tuberculosis is diagnosed in swine by the same 
methods as in cattle although several of the special tests are not 
applicable to swine. The most usual means are (a) by the lesions; 
(b) finding the specific bacterium; and (c) the use of tuberculin either 
subcutaneously or by the intradermal test.
