test. Owners of valuable horses, as a rule, strongly object to 



their horses being "coughed," because the repeated performance 



of this test, especially if it is roughly done, is apt to injure the 



larynx. When sending up a hunter for sale to any of the public 



horse marts, such as Tattersall's, or that of Warner, Sheppard and 



Wade, it is much better, supposing that the animal's powers of 



breathing are all right, to state that the horse is sound in wind, 



and to forbid his being tested for it, than to subject him to the 



annoyance and ill effects of being grunted and coughed by every 



passing idler. 



" We are able to recognise the wasting of the muscles by feeling the larynx 

 of the roarer with the fingers ; for the left arytenoid allows itself to 

 be pushed back more easily and more deeply down than its fellow. This pro- 

 cedure sometimes sets up roaring while the animal is at rest " {Friedberger 

 and Frohner). 



ROARERS AS STUD ANIMALS.— Owing to the strong influence 

 of hereditary predisposition in this complaint, a mare or stallion 

 that is affected by roaring, should on no account be used for stud 

 purposes in Great Britain, or in any other country in which the 

 climate is at all favourable to its development. I have already 

 pointed out that there is no objection to breeding from roarers 

 in countries like India, South Africa, and South America, the 

 respective climates of which are antagonistic to its propagation. 

 Fleming states that the hereditaiy influence of a roaring stallion 

 in conferring this disease on his offspring usually increases with 

 age. 



TREATMENT. — Acting on Mr. Harry Goodall's idea of the bad 

 effect which the continued i>ractice of feeding horses from raised 

 mangers has on the muscles of the neck, and taking into considera- 

 tion the remarks I have already made on the influence of food in 

 the production of this disease; I w^ould advise that on the first 

 symptoms of roaring being perceived, the animal, supposing that 

 he was otherwise in good health, should be turned out to graze 

 during the day; or be given grass or other green meat instead of 

 hay and chaff, and be fed on a level with the ground and not from 

 a raised manger. He should be kept warm by clothing, and should 

 have the freest possible ventilation in his stall. "I have no doubt 

 that roarers might be improved a stone if they were trained from 

 an open shed, sheltered from wet and rain, keeping them warmly 

 clothed and always in the open air" (Admiral Rous). I have seen 

 good results from 2:iving a roarer a dailv allowance of linseed, 

 say, one pound, or 4 oz. of linseed oil. The linseed may be in 

 the form of linseed meal mixed through the food, of linseed tea, or 

 of linseed mash.
