212 ANTHRAX. 



external and internal, Avitli the citron-coloured, jelly-like exu- 

 date so common to anthrax. 



When the symptoms have been marked with much severity, 

 rapidity of development, and with a fatal termination, I have 

 not been able to observe structural changes so marked as in 

 cases where the animal lived longer, and the severity of the 

 symptoms was less obvious. This would seem to obtam in 

 more general diseases than anthrax. The animal seems cut 

 down by the poison before time has been given for structural 

 alterations. 



In the foregoing observations we have glanced at the prin- 

 cipal changes which may be expected in anthrax generally. 

 It wiU be evident that we shall not frequently meet with the 

 whole of them in one individual case, though such may occa- 

 sionally happen ; but that the different symptoms will lead us 

 to look to the various localizations of the lesion. 



Thus when delirium, or other disturbance connected with 

 the nervous system, predominates, we shall expect to find the 

 most marked structural changes in the nerves or nerve-centres. 

 When enteric pain is specially manifested — in the bowels, and 

 so on — and as there is most frequently a complication of 

 symptoms, so on post-mortem examination do we find more 

 than one organ or set of organs affected. 



Of that condition of the intestines associated with carbun- 

 cular elevations, sloughing, and formation of deep yellow- 

 coloured ulcerated cavities, indisposed to heal — spoken of and 

 described by some German authors — I have had no experience. 



When occurring as giossanthrax, the additional charac- 

 teristic tissue-changes are associated with the tongue, larynx, 

 pharynx, and structures connected with and contiguous to 

 these. 



The infiltration, with the peculiar exudate, is usually very 

 extensive on the retro-pharyngeal and laryngeal tissue ; while 

 the glands, both lymphatic and salivary, are much enlarged, 

 chiefly with the exudate, mixed with dark-coloured blood. 

 Along the buccal membrane, as also on the tongue, we may 

 sometimes see an angry looking sore, which has resulted from 

 the rupture of a vesicle, and the after-irritation of the exposed 

 surface, the entire submucous structure being either generally 

 or in patches swollen and infiltrated. The membrane over
