202 ANTHRAX. 



able to rise again, and after struggling convulsively for a short 

 time quietly succumbs. 



The course of this form of anthrax in the horse has in my 

 experience been uniformly progressive. There has been no 

 well-defined remission of symptoms, but in all, even if at some 

 time during their rather short course they have given any 

 evidence of improvement, it has only been that of the 

 symptoms remaining stationary ; and after a very short time 

 they have again shown fresh activity, or have to the original 

 ones of special pyrexia added those indicative of the disturb- 

 ances of other organs and functions. In no case which I can 

 recollect have I been favoured with a recovery. 



2. Symptoms of Anthrax as a Blood Disorder in which certain 

 external manifestations are a prominent feature, but which 

 from want of more positive knowledge as to its aetiology, and 

 taking anthrax to be essentially hsemal parasitism, it would 

 probably be orthodox to regard as simply ' anthracoid ;' still 

 from its having been described by most writers on the subject 

 under this head, and its not having been proved not to be 

 anthrax, we follow the same order. 



Amongst our patients, others than members of the family 

 ' equidse,' we are aware that anthrax with local complications 

 is a very common form of the disease ; with the horse, at least 

 in this country, it is, we are inclined to beheve, not at all 

 common. 



A diseased condition, spoken of by German writers under 

 the term ' anthrax typhus,' and named by English pathologists 

 purpura hsemorrhagica, we do not consider has yet been satis- 

 factorily determined to be a form of anthrax, so we have pre- 

 ferred to consider and speak of it separately. 



The only forms of anthrax with local complications with 

 which I am conversant as occurring in the horse in this 

 country are those known as glossanthrax, or malignant 

 glossitis, and anthracoid angina — malignant sore throat. 



Neither of these conditions are common ; the first I have 

 seldom seen in the horse unassociated Avith the latter, while 

 this latter independent of the former is even of rarer occur- 

 rence. 



Whether glossanthrax be due or owe its origin to a general 

 infected condition, a primary charging of the system with
