Diseases of the Respiratory £>rga'ns. 189 



Btarting on a journey the subjects pass dung very frequently 

 at first and after traveling some distance may go much 

 better. Their muscular systems are soft and flabby and 

 they run down rapidly in active work. Frequent aggrava- 

 tions of the symptoms may be seen in connection with 

 overloaded stomach, costiveness, a hot close stable, a 

 thick mnggy atmosphere, or a very severe day's work. 



The symptoms may be temporarily masked or hidden 

 by restriction in diet, abstinence from water and the use 

 of sedatives, but there remains an unnatural action of the 

 nostrils, and a full drink of water, and above all a free 

 supply of water and hay will bring back the symptoms in 

 aU their intensity. 



Treatment. Turning out on natural pastures or feeding 

 cornstalks or other laxative food will relieve, and even 

 cure mild and recent cases. Feeding on dry grain with 

 carrots, turnips, beets, or potatoes and a very limited 

 supply of water wiU enable many broken-wiuded horses to 

 do a fair amount of work in comfort. Hay should never be 

 allowed except at night and then only a handful clean 

 and sweet. The bowels must be kept easy by laxatives 

 (sulphate of soda 2 or 3 oz.), the stable well aii-ed, and 

 sedatives (digitalis, opium, belladonna, hyoscyamus, stra- 

 monium, lobelia,) used to relieve the oppression. If a 

 white discharge from the nose coexists tonics should be 

 given as for chronic bronchitis, to which wild-cherry bark 

 may be added. Tar water as the exclusive drink is often 

 useful and a course of carminatives (ginger, caraway, 

 cardamoms, fennel, foenugrec,) may be added with advan- 

 tage. But nerve tonics and above all arsenic in 5 grain 

 doses daily, and continued for a month or two, are espe- 

 cially valuable. 



No broken-winded horse should have food or water for 

 from one to two hours before going to work.
