ROARING. 



THIS is a disease in which there is a loud sound pro- 

 duced by the air passing through a restricted tube dur- 

 ing respiration, while the animal is undergoing great 

 exertion. The constriction in the air passage is in the 

 larynx, and in nearly all cases is due to a paralysis of 

 the muscles on one side of the throat, which allows the 

 muscles on the other side to draw the cartilages toward 

 that side, and thus obstruct the passage of air through 

 the windpipe. If the constriction is due to a thicken- 

 ing of the membranes of tne throat, following a sore 

 throat, there is good ground to hope for a recovery, 

 and I have known many such cases ; but when it is due 

 to a paralysis of the muscles of one side of the throat, 

 the case is a hopeless one, or at any rate is only curable by 

 an operation, and then the chances are rather against a 

 perfect cure. If the roaring follows a severe sore throat, 

 it is always prudent to attempira cure, and nothing will 

 be so successful in bringing about that event as the 

 administration of HEAKD'S QUININE CONDITION POWDERS 

 and the application 3 times a day of HEARD'S AMERICAN 

 EMBROCATION, to be continued until the neck is slightly 

 blistered. The animal to have gentle work.
