EOAEING. 



A favorite remedy for heaves, used by Prof. Dick, principal of 

 Edinburgh College, and undoubtedly of great value, is : 



Camphor. 



Digitalis. 



Opium. 



Calomel. Of each, 30 grains. 



Make into one powder or ball, and give once a day for a week. If no improve- 

 ment is noticeable, omit the calomel, and give for a week or two longer. 



2 ounces Spanish brown. 

 2 ounces tartar emetic. 

 4 ounces resin. 

 2 ounces ginger. 

 Mix and give two teaspoonfuls twice a day in the feed. 



% ounce vegetable tar, in mass. 

 ^ ounce gum camphor. 

 1 drachm tartar emetic. 



Form into a ball, one of which is to be given once a day. 



1 ounce indigo. 

 1 ounce saltpetre. 

 1 gallon rain-water. 



Mix and give a pint twice a day in the feed. 



ROARING. 



This is a very annoying difficulty, for which there is no satis- 

 factory treatment. Like chronic cough, it often follows an attack 

 of laryngitis or of distemper (strangles), and in these cases we 

 believe it is owing to a wasting (atrophy) of the muscles of the 

 head of the windpipe (larynx), whereby its calibre is diminished, 

 and when the air rushes in during violent exertion, a roaring 

 sound is produced. The senseless and cruel method of tight- 

 checking, in addition to the throat latch being often buckled so 

 tightly as to obstruct the breathing, is also a very common excit- 

 ing cause. 



Symptoms. When the horse is not excited, and so long as the 

 air passes in a uniform rate through the larynx and windpipe, the 

 animal does not feel any inconvenience ; whenever he is excited 

 or galloped, causing a rush of air, the roaring noise is produced. 

 The sound in ordinary circumstances is only produced on inspira- 

 tion, but in very severe cases the sound is audible both on inspira- 

 tion and expiration.
