414 CALOMEL AND CRUDE MERCURY, [BOOK II. 



No. 2. — Purgative Ball. 

 Barbadoes aloes, 4 drachms. 

 Gamboge, 1|- drachms, 

 Prepared kali, 2 drachms, 

 Ginger, 1 drachm, 

 Oil of amber, a tea-spoon full, 

 Syrup of buckthorn sufficient to form the 

 ball for one dose. 

 No particular care need be taken of the horse, 

 but he should not take any gruel for the two days 

 that the mercury is in him, as directed by James 

 While, but give him bruised corn or other dry food 

 with little water, the calomel not having entered 

 the system. Neither does he require any of the 

 exercises usually forced upon patients " in physic." 

 Let a week elapse ere the same bolus and purge 

 are repeated as before, when they seldom fail to 

 bring away whatever worms he may have in him. 

 Instead of the foregoing, some persist in the fol- 

 lowing old method, by way of laxative mercurial, 

 which, however, we must premise, seems much too 

 strong, notwithstanding the high character some 

 bestow on it. 



No. 3. — Laxative Alterative Balls. 

 Quicksilver, 1 ounce, and 

 Venice turpentine, 2 ounces. 

 These being well rubbed together in a mortar,
