The skin lesio7ts are vascular neoplasms containing bacilli and 

 usually invested with a covering of horn, but sometimes, on the 

 legs and feet raw. The morbid growth may be rounded or con- 

 ical, narrowing to a point. The lesions of the buccal mucosa 

 begin as small, grayish swellings on the angle of the mouth, 

 palate, tongue or larynx which grow out into more or less 

 rounded vegetations. The lesions of the liver aud lungs are 

 mostly miliary with the usual tubercular features, but they may 

 grow to larger size, as a pea or bean. In the cancelli of bones and 

 on their surface, the lesions resemble those of the mammal. 



The cutaneous form has been held to be the counterpart of 

 warty lupus of man, the more plausibly that the disease is de- 

 veloped by inoculation from tuberculous men. The arthritic 

 type represents what is described as gout in parrots. 



In any case the recent miliary lesion presents the true tuber- 

 cular type of a central giant cell or cells with bacilli, surrounded 

 by epithelioid cells, and they in turn by small, rounded lymphoid 

 globules. 



PRIMARY AND SECONDARY INFECTION. 



The estimate of the relative, early or late infection of two or- 

 gans or tissues may often be made with reasonable accuracy 

 from the fact that the lesions in one organ are old, caseated, cal- 

 cified or sclerosed, while those in the other organ are all recent, 

 with vascular environment and almost devoid of caseation or 

 other degenerative process. We cannot safely predicate our de- 

 cision on the greater number of old lesions in one organ rather
