8 Roaring in Horses. 



been effused in the windpipe or its branches, which, be- 

 coming sohd, obstructs, in a greater or less degree, the 

 passage of air.''^ And later the same writer elsewhere 

 states : " There is another complaint of the lungs, or parts 

 connected with them, and an incurable one, which the pur- 

 chaser should be guarded against. This disease is named 

 Roaring, from the wheezing noise a horse makes when rode 

 fast, particularly when galloped up a hill : it is sometimes 

 so considerable as to be heard at a distance of many yards ; 

 but in walking, or moderate exercise, it can seldom be per- 

 ceived. The method which dealers usually employ to 

 detect this complaint at a repository, where no other trial is 

 allowed, is to whip the horse under the belly and make him 

 turn suddenly, or by making him leap over the bar ; if he is 

 a roarer, this sudden exertion causes him to groan. But 

 this criterion should never be depended upon when an 

 opportunity offers of galloping the horse."^ 



Percivall,^ in 1824, treats of Koaring in a more com- 

 plete manner than any previous English writer ; and again 

 in 1840 he deals with it in another work,* though more 

 briefly and no more satisfactorily. Youatt in 1833,^ John 

 Field in 1837,^ Ferguson in 1838,"^ Turner and Cartwright 

 in 1849,^ Owles in 1854,^ Eeeve in 1858,i<^ and other writers 

 have devoted much attention to it; while in 1882 I ven- 

 tured to give the result of my somewhat lengthy experience 

 and investigations into the pathology of Roaring.^ 



It was not until the present century had been somewhat 

 advanced, and veterinary surgeons were devoting more 

 attention to anatomy and physiology, but especially to
