62 INFLUENZA. 



thirty beats per minute, and the possession of a settled wiry 

 character. Respiration, in the former cases, is not much 

 altered ; but in the latter, where the increase in number is 

 marked, the respirations are proportionately increased also, 

 and with both characters of the pulse the nature of the 

 respirations is abdominal. 



When the prostration is great — for in all it is a distinct and 

 peculiar feature — I have observed that the membrane of the 

 mouth and tongue is marked with petechia3, or blood-spots, 

 often of a considerable size, and that there also exists effusion 

 and inffltration of a straw-coloured exudate beneath the 

 buccal membrane on the inferior and lateral sides of the 

 tongue, while the mouth is filled with ropy saliva, the Avhole 

 appearances betokening the application, or at least such as we 

 would expect to see from the action, on the parts of a smart 

 rubefacient. The temperature of the body, taken in the rectum, 

 is not, during the development and continuance of the 

 abdominal symptoms, so markedly high as in the pulmonic 

 form of the disease, or even in some stages of the simple 

 catarrhal. No doubt it is high — 102^ to 104° F. — but rarely 

 does it pass beyond 105° F. ; while, like all the other forms, the 

 fever is not merely simply continued, but truly remittent. 



This special form of influenza in the horse I have most 

 frequently encountered aftecting animals performing a fair 

 amount of work, and enjoying good, rather liberal dieting. 



One phase of its development where fatal results are rapidly 

 reached, attended with catarrh and other changes of the 

 mucous membrane of the bowels, and liaBmorrhagic markings 

 of large extent in the stomach and anterior parts of the 

 alimentary canal, is found closely associated with imperfect 

 sanitary conditions and the action of other extrinsic 

 debilitating influences. 



4. The Rheumatic Form. — Like the greater number of the 

 manifestations of this fever, the rheumatic, in its pecuhar 

 diagnostic symptoms, rarely exhibits itself independently of, 

 but usually as a sequel to, the occurrence of the ordinary 

 catarrhal ; or at least the greater number of such cases are 

 preceded by or accompanied with the specific inflammation of 

 the mucous membrane of the upper or loAver air-passages so 

 diasfnostic of influenza.
