a great many roarers. From the accounts of British veter- 

 inarians we cull the following statements concerning it : It 

 is produced by obstruction in some part of the respiratory 

 canal, oftenest in the larynx, and next to that in the trachea. 

 Sometimes these obstructions are originally caused by bands 

 of coagulated lymph in the trachea, or elsewhere. Chronic 

 cough occasionally terminates in roaring. The majority of 

 roarers are draught horses, and horses of quick draught. 



Facts are said to establish the hereditary predisposition to 

 this aifection beyond a doubt. " Major Wilson, of Didling- 

 ton, England," had a valuable stable horse; but he was a 

 roarer, and so were many of his colts. On the other hand, 

 "Eclipse" and "Taurus," two celebrated racers of England, 

 were roarers, but none of their colts were. 



This is a rather strange concatena^tion of assertions and 

 contradictions to be derived from the same sources ; and thus 

 \^e leave the subject and the roarers of Euijland.
