124 Roaring in Horses. 



fever, is left with his nervous system permanently damaged, 

 and is never a horse again. . . . His body temperature, even 

 when at rest, stands abnormally high, and on the smallest 

 exertion in the sun it rises quickly. He never cools down, 

 and stands and blows over his food in the stable — he is in 

 a state of chronic fever. A little work in the sun, and he 

 falls, registering a very high temperature. A horse of this 

 class becomes a Roarer, and is of little use here."^ 



I have already alluded to English troop-horses becoming 

 Roarers in South Africa and Egypt. In the latter country 

 an extraordinary number became affected, but they were 

 exposed to various causes besides the thermic one. Of this 

 I might cite many instances, but content myself with giving 

 the following, furnished me by Veterinary Surgeon (First 

 Class) Case, Army Veterinary Department. He says : 



" During the campaign of 1882, in Egypt, I served with 

 G Battery, B Brigade, Royal Horse Artillery, a corps I had 

 been with for two years. When we embarked, on August 2nd, 

 there was not a horse affected in its breathing in the ranks ; 

 but soon after landing many of the horses, more especially 

 the draught ones, began to show symptoms of Roaring. This 

 began to appear during the latter part of our first march 

 from Ismailia, which place we left on August I7th, at 

 four o'clock in the afternoon, and continued marching until 

 five o'clock the next morning, when we halted for four 

 hours. During the early part of the night we were subjected 

 to a fearful dust-storm, and the bank of the Fresh-water 

 Canal, on which we were marching, was very rough going ; 

 so that at the time I attributed the Roaring to over-exhaus- 

 tion — the horses only just having landed, and being some- 

 what out of condition. On continuing, the march was more 

 distressing, as the direction lay across the desert, the guns 

 and waggons having to be pulled through deep sand. The 

 Roaring of many of the horses then became much more 

 perceptible, and could be heard at some distance. More
