474 THE STOCK owner's ADVISER. 



The ovum gains access to the stomach during the process of feed- 

 ing. It is there set free, enters the circulation, and is carried to 

 its favorite ha'bitation. The disease prevails on both sides of 

 Lake Erie, in the State of Ohio, and in the Dominion of Canada. 

 It is frequently seen in Virginia, and throughout the low-lying 

 districts. 



Symptoms. — The animal has a husky cough, which increases 

 in frequency and severity by exertion. The appetite is impaired, 

 and there is a discharge from the nostrils. The parasites may 

 be detected by the naked eye, if the discharge be closely exam- 

 ined. 



Treatment. — Change the animals to a higher and dr^^er pas- 

 ture, if possible. Turpentine, one ounce; linseed oil, eight 

 ounces, should be given in a drench. Inhalation of chlorine gas 

 will destroy the parasites. Place three or four of the affected 

 animals in a loose box; the chlorine gas may be generated by 

 pouring sulphuric acid over a mixture of sodium chloride and 

 magnesium black oxide. When the animals begin to cough they 

 should be liberated. Inhalation of burning sulphur in a close 

 stable is a very safe and effectual remedy.
