branes are red, the 

 [bowels constipated, and the urine is scanty. In a few hours the symp- 

 toms change materially, the pulse becomes more frequent and small, 

 the' legs and ears are cold, and breathing becomes very difficult, and 

 there is rapid prostration of strength. 



In the second stage, which is reached about the second or third 

 day, a watery secretion mixed with mucus is expelled in coughing. 

 (See Fig. 994.) The cough becomes less frequent and painful. The 

 crisis of the' disease is reached about the fourth or fifth day. Favor- 

 able signs are a gradual reduction of temperature, and a fuller, 

 softer, and less rapid pulse. The appetite returns, secretions and 

 excretions become natural, and the animal becomes convalescent by 

 the tenth day. An unfavorable termination is indicated by a sud- 

 den fall of 5° or 6° in the temperature, the pulse becoming small and 

 more frequent. 



Treatment. — Put the animal in a warm stable, allow plenty of 

 pure air, a liberal supply of tempting food, and unlimited nitrated 

 water. The object is to keep up the strength of the patient, and 

 avoid lapse in 'the chronic stage. If the bowels are torpid, admin- 

 ister enemas, but not cathartics, as they may cause diarrhea, and 

 may fatally tax the strength of the patient. Give the following two 

 or three times a day : — 



Acetate of ammonia rrr. ,. 8 oz. 



Water . . . ; 1 pt 



Or— 



Spirits of nitric ether 8 oz. 



Water 1 pt.
