MALADIE DU COIT. 261 



times intermittent, disappearing for a week or two, and then 

 reappearing with a greater intensity. 



Alter some time the appetite becomes exceedingly capricious, 

 but is never entirely lost, the animal continuing in many cases 

 to eat till within an hour of its death. 



One or both hind extremities now become paralyzed, causing 

 the sufferer to fall upon its litter, and the entire muscular 

 system becomes atrophied, but more especially the hind quarters 

 and legs. 



The mucous membrane of the nose becomes of a yellow and 

 the buccal membrane of a leaden colour ; and there may be slight 

 constipations. 



Unless pneumonia or other complications of the respiratory 

 organs set in, the respiration remains natural. M. Eodloff has 

 often observed horses suffering from this disease become broken- 

 winded. 



In the mare, one or other half of the mammary gland some- 

 times becomes the seat of an inflammation, which usually termi- 

 nates in suppuration. 



In the incubative stage of the disease, numerous cutaneous 

 tumours form, which, unlike those of farcy, are entirely situated 

 in the skin, and do not invade the subcutaneous tissues. They 

 are of various sizes, but may be divided into three — a small, a 

 medium, and a large size. 



The small tumours, which appear suddenly, and may as sud- 

 denly disappear, have attained, when first seen, their full dimen- 

 sions. This, however, is not absolutely without exception, as in 

 some instances an increase of circumference has been observed. 

 The middle and large-sized tumours commence by a circle, on 

 which the hairs stare ; the centre of the circle gradually fills in, 

 and the tumour becomes fully developed within twenty-four 

 hours. Their duration is variable, but may be said to be from 

 four to nine days. The disappearance of the small tumours may 

 be effected in a night, while that of the larger ones takes place 

 more gradually; temperature and sensibility in the former are 

 not above that of surrounding parts, while in the latter both are 

 considerably exalted. Their disappearance is soon followed by 

 the eruption of a fresh crop, which may be situated on the same 

 or on different parts of the body. — (M. Eodloff.)^
