MEGRIMS. 133 



usual amongst over-fed horses, which are suffered to 

 remain for days together in the stable, and then driven 

 fast up hill with a tight bearing rein or small collar, 

 both of which aid in preventing the free return of the 

 blood to the heart. In this case congestion of the 

 vessels of the brain will take place, while in others 

 there is evidence of a diseased heart. 



This disease cannot be mistaken : the horse, after pro- 

 ceeding about one mile from the stable, will shake his 

 head and ears, as though flies were annoying him, or 

 as if some extraneous substance had got into his ear ; 

 if stopped immediately, he will rarely fall ; but if not, 

 he will stagger, hold his head aloft and on one side, 

 and drop : the attack usually lasts about five minutes, 

 when the horse will resume his journey as before, with 

 no apparent inconvenience, though he will very fre- 

 quently break out into a sweat. The treatment should 

 consist of the following ball once a week for a month, 

 and given with a bran mash : two drachms of Barba- 

 does aloes, one drachm of emetic tartar, and two drachms 

 of ginger. The horse should be fed very lightly 

 previous to work.
