^4 Roaring in Horses. 



is more frequent. Among horses of the Reserve, 3'87 ; 

 heavy cavahy, 219 ; light cavalry, 119 ; and artillery 

 horses, 0-97 per cent., purchased during four years, were 

 Roarers. As evidence that the defect is on the increase, he 

 notes that among the horses purchased at his depot in 1880 

 there were thrice the number of Roarers than there were in 

 1871. His remarks with regard to Algeria corroborate the 

 observations of our own army veterinary officers with regard 

 to India. He asserts that, practically, the disease does not 

 exist in that country, for since the establishment of 

 remount depots there not a case has been reported. In a 

 total of 1,515 stallions, purchased by the depots at Blidah, 

 Constantino, and Mostaganem, since 1845, not a single horse 

 had been cast and sold because of Roaring. Since 1878 

 these depots had also purchased 16,721 troop-horses, and 

 the defect had not been observed in any of them. 



In the Veterinary Reports of the German Army accessible 

 to me, there is no mention of Roaring, though the diseases 

 which it often follows appear to be quite as prevalent among 

 the troop-horses as among our own ; and if we are to judge 

 by the frequent allusions to it in veterinary literature, it 

 might be concluded that in Germany it is as common as in 

 England. 



In Spain and Italy it is very infrequent. 



It is impossible now to ascertain to what extent Roaring 

 prevailed among horses in the United Kingdom previous to 

 the present century. When such veterinary authorities as 

 Coleman, Percivall, Youatt, White, and others, began to 

 describe it more than half a century ago, though little was 

 known as to its pathology, it was evidently a common affection 

 (if we may speak of a symptom as such), and was the cause of 

 much speculation and discussion. There are grounds for 

 believing that it has become much more prevalent in recent 

 years, and especially among light, well-bred horses ; and if 

 current reports, as well as one's own personal experience, 

 are taken into, account, Roaring must be very common
