352 Diseases of Sheep, 



The symptoms mentioned slowly increase in severity until, 

 in about a week, there are evident emaciation and great pros- 

 tration. The nasal discharge is thick and glutinous, some- 

 times tinged with blood ; the eyes are half closed, and the 

 lids matted by a yellow secretion. The appetite has almost 

 gone, and the pulse scarcely perceptible. The respiration is 

 labored and difficult. In well-fed sheep the bowels continue 

 natural, as a rule ; but in those on insufficient or poor diet 

 the bowels may become inflamed and swollen, and dysenteric 

 symptoms arise. The excrement is voided with pain, and it 

 is mixed with blood. The attack usually commences with 

 constipation. The average length of the disease is ten to 

 fifteen days. 



After death, the principal and characteristic lesion is a 

 highly inflammatory, thickened and congested appearance of 

 the lining membrane of the nostrils and nasal cavities 

 throughout, sometimes passing into ulceration. This condi- 

 tion may extend, with more or less intensity, to the mucous 

 membrane of the upper throat and gullet ; and more rarely 

 down the latter, and to the bowels. 



Treatment, — It must be acknowledged that no plan of 

 treatment has been tried with very satisfactory results. Cer- 

 tain rules are, however, of considerable value. No bleeding, 

 purging or depressants must be used. Concentrated and 

 nourishing food and stimulants are demanded from the out- 

 set. A dry and equable temperature is important. 



In regard to medicines. Col. Randall believes that he has 



derived advantage from the use of corrosive sublimatey in 



small and repeated doses, providing that it is commenced 



early in the disease. He combines it as follows : — ■ 



No. 394. Corrosive sublimate, 8 grains. 



Rhubarb, 1 oz. 



Ginger, 



Gentian, of each 2 oz. 



Simmer the last three articles in a quart of water, for fifteen minutes, 

 strain, and add the sublimate. The dose is two tablespoonfiils, twice 

 a day.
