becomes affected to a considerable extent. Abdominal 

 breathing is not present. Any undue disturbance of 

 respiration may be detected by closely watching the nostrils, 

 which in this case are perceptibly agitated, plainly indi- 

 cating difficult respiration. At this stage of the disease 

 there are certain external symptoms manifested as follows : 

 Coldness of the extremities, ears, and muzzle ; the legs 

 may be cold, and in a hour hot, or one or more legs may be 

 hot and the rest cold. 



The mucous membranes are at first reddened and dry ; 

 soon there is a discharge from the nostrils, which is generally 

 very profuse, and if of a yellowish colour we may regard it 

 as a favourable sign, and, as a rule, the patient from this 

 time does well ; but if the discharge is of a brownish-red 

 colour, we must regard it as a bad symptom, as it shows the 

 bronchial tubes are considerably affected, and in such a case 

 the prognosis should be guarded. In many cases which 

 terminate fatally, the breathing becomes extremely difficult ; 

 there is flapping of the nostrils, cold sweats break out be- 

 hind the ears and shoulders, and perhaps the whole body 

 may be covered with a cold sweat; pulsations 100 to 120 

 per minute, often fluttering and irregular ; extremities cold ; 

 and the animal wanders about in an aimless sort of manner, 

 apparently in a half unconscious state. A discharge of a 

 brownish hue issues from the nostrils, and death quickly 

 ensues. 



Sometimes the liver is involved. This may be known by 

 the mucous membranes taking on a yellowish tinge. Ab- 

 dominal complications are developed in some cases, and are 

 manifested by the usual symptoms. If enteritis sets in, the 

 chances of recovery are poor, the case being very likely to 

 terminate fatally. In some cases there is considerable 

 swelling of the legs, and of the sheath if a gelding. If 

 these cedematous swellings occur in the early stages of the
