benefited. The animal is to be carefully dieted, the food 

 being of the best and cleanest, and must be absolutely free 

 of dust. Pure water, as well as food, is to be given in well- 

 regulated quantities. Distressing symptoms may be relieved 

 by giving a laxative, followed by sedatives, as hydrarg. 

 subchlor., camphor?e, opii pulv., digitalis, aa. 5ss., a couple 

 of times a day. The use of the following is also attended 

 with benefit : Acid, arsen., grs. ii. ; ferrisulph., 5i. Nerve- 

 stimulants, as strychnia or nux vomica in the usual doses> 

 are also of use. The hay should be free from dust and 

 dampened ; clean straw is far preferable to dusty hay. 

 Aquae calcis, in conjunction with ol. lini, may be given as 

 being antacid and laxative ; antim. tart, is very useful in 

 many cases. But medicinal agents will do no good what- 

 ever unless assisted by a rigid adherence to the regulations 

 as to diet, etc., as above set forth. If the disease is taken 

 in time and properly treated, a cure can in many cases be 

 efiected. Dick's prescription is the leading one, and pro- 

 bably the best. In the treatment of broken-wind, potassium 

 bicarb, and arsenic are sometimes given in combination. 

 Fowler's solution is also used. 



A horse possessing a round chest and largely developed 

 organs of digestion is more liable to become broken-winded 

 than a horse of different conformation. Unscrupulous 

 dealers frequently administer lead pellets, large doses of 

 oil, etc., which, by acting mechanically, relieve the symp- 

 toms for the time being, and enable the owner to sell the 

 animal. An animal is often kept short of food, the same 

 purpose, that of deception, being thereby effected. All 

 suspected animals should be allowed to stand quietly all 

 night, heavily fed and watered on the following morn- 

 ing, when by sharp exercise the fraud may be readily 

 exposed.
