been added in the proportion of half an ounce to a pound. As 

 an emollient poultice for grease and cracked heels, and especially 

 if accompanied by much unpleasant smell, there is nothing prefer- 

 able to a poultice of mashed carrots with charcoal. For old 

 grease some slight stimulant must be added, as a little yeast or 

 the grounds of table beer. 



There are two errors, in the application of a poultice, and par- 

 ticularly as it regards the legs. It is often put on too tight, by 

 means of which the return of the blood from the foot is prevent- 

 ed, and the disease is increased instead of lessened ; or it is too hot, 

 and unnecessary pain is given, and the inflammation aggravated. 



Powders.— Some horses are very difficult to ball or drench, 

 and the violent struggle that would accompany the attempt to 

 conquer them may heighten the fever or inflammation. To such 

 horses powders must be given in mashes. Emetic tartar and 

 digitalis may be generally used in cases of inflammation or fever ; 

 or emetic tartar for worms ; or calomel or even the farina of the 

 croton-nut for physic : but powders are too often an excuse for the 

 laziness or awkwardness of the carter or groom. The horse fre- 

 quently refuses them, especially if his appetite has otherwise be- 

 gun to fail ; the powder and the mash are wasted, and the 

 animal is unnecessarily nauseated. All medicine should be given 

 in the form of a ball or drink. 



Prussic Acid. — See Acidum Hydrocianicum. 



GluiNiNE. — See under Bark, Peruvian. 



Raking. — This consists in introducing the hand into the rec- 

 tum of the horse, and drawing out any hardened dung that may 

 be there. It may be necessary in costiveness or fever, if a 

 clyster pipe cannot *be obtained ; but an injection will better 

 efiect the purpose, and with less inconvenience to the animal. 

 The introduction of the hand into the rectum is, however, useful 

 to ascertain the existence of stone in the bladder, or the degree 

 of distension of the bladder in suppression of the urine, for the 

 bladder will be easily felt below the intestine, and, at the same 

 time by the heat of the intestine, the degree of inflammation in it 

 or in the bladder may be detected. 



Hesin. — The yellow resin is that which rerriains after the 

 distillation of oil of turpentine. It is used externally to give 

 consistence to ointments, and to render them slightly stimulant. 

 Internally it is a useful diuretic, and is given in doses of tive or 

 six drachms made into a ball with soft soan. The common 

 liquid turpentine is, however, preferable. 



HowELS. — The manner of rowelling has been already de- 

 scribed. As exciting inflammation on the suriaoe, and so les- 

 sening that which had previously existed in a neighboring but 

 deeper-seated part., they are decidedly inferior to blisters, for they
