ENTOZOA OF THE SHEEP.

and flabby, with a sort of crackling sound and a watery or blub- 

 bery feeling, they are unsound. Professor Simonds states that 

 a dry, scaly state of the skin on the inner part of the thighs, par- 

 ticularly where it is uncovered with either wool or hair, is early 

 recognized as a sign, and that an examination of the eye will 

 materially assist in determining the question of disease. If dis- 

 eased, the vessels of the eye are tinged with a pale or yellowish 

 colored blood. 



The progress of the rot is slow. The animal becomes dull, the 

 mucous membranes become pale, skin is dry, the flanks hollow, 

 back weak, the belly tucked up. The eyes become yellow, and 

 dropsical swelling is seen in various parts of the body. 



Treatment. — The unsound pastures should be a'bandonefil. 

 The sheep may be moved to dry pastures and an abundant supply 

 of salt given. 



OESOPHAGOSTOMA. 



This parasite shows itself by the fonnation of little tumors or 

 nodules in the mesentery and intestines, resembling tubercular 

 deposits. In the tumor will be found little round worms. The 

 male is less than a half inch; the female is three inches in length. 



Symptoms. — The symptoms are not well shown. A sheep 

 should be killed in order to find out the nature of the disease. 



STRONGYLTJS FILARIA. 



This parasite affects cattle also. They are located and lay 

 their eggs in the bronchial tul)cs. The male parasite is from one 

 to two inches; the female from two to three inches in length. 



Symptoms. — Cough, difiicult breathing, and panting. Shreds 

 of mucus may be passed up. The animals may have a fair appe- 

 tiie, and if they live over winter the parasites will disappear. 



TpvEatment — Preventive. — It will be some time before the 

 sheep can be put upon the land, and they should be fed well. 



Medicinal Treatment. — Give one to two drachms of turj^en- 

 tine, in oil, and inhalations of suli)liur. The shcc]) should be con-
