CHAPTER III. 



PREVALENCE OF ROARING. 



Roaring is much more prevalent in western and northern, 

 than in eastern and southern countries. In the hitter, 

 indeed, it is rarely observed among the native horses. In 

 India, for instance, the indigenous horses are extremely 

 seldom affected in this way, those imported from Australia 

 being much more liable ; though there appears to be a ten- 

 dency to disappearance of the hereditary predisposition 

 which may be present in these exotics. Hayes says : " In 

 India, Roaring is almost unknown among horses bred there, 

 although many of their imported sires have been confirmed 

 Roarers. I have known instances of imported horses — and 

 one case of a colt bred in India, whose dam, an Australian 

 mare, was a Roarer — which appeared to be confirmed 

 Roarers, become, after a time, perfectly sound in their wind. 

 The disease appears to be nearly as rare among Arabs as it 

 is among Indian stock. "^ 



Mr. Oliphant, Principal A^eterinary Surgeon in India, but 

 whose experience has been chiefly gained in Bengal, in reply 

 to my inquiries, writes: "The two classes of horses I have had 

 most to do with in India are stud-breds (including country- 

 breds, as used in the Government service) and Australian 

 horses. In the studs Strangles was very rife, but the stud- 

 bred horses were, in my experience, peculiarly free from 

 Roaring, and I do not think that the country-breds of the 

 present day, got by Government sires, are any more liable 

 to it. I have seen a few cases among Austrahan remounts,
