AND PHARMACOPCEIA. 499 



is scarcely an old book on farriery in which it is not recom- 

 mended for horses as an ingredient in purgative balls or physic ; 

 which practice is still followed by farriers, Avho generally put 

 two or three drachms of jalap into every dose of physic. It was 

 tried, however, first at the Veterinary College, and was found 

 to have no purgative effect on the horse, though given in con- 

 siderably larger doses than even farriers employ ; but I have 

 observed that in a very large quantity it occasions sickness, 

 and some degree of purging, though its effects in this way 

 are by no means sufficient to induce any one to employ it as a 

 purgative alone. 



I once gave eight ounces of jalap at one dose to a glandered 

 horse, that was in other respects healthy, and had not been 

 taking any other medicine : in about six hours the horse ap- 

 peared sick, and in pain ; he refused both food and water ; 

 during the night he appeared to have had some small watery 

 stools, several of which were perceived also the next day ; but 

 they were in very small quantity, and accompanied Avith pain. 

 The sickness continued all the second day, and on the following 

 he recovered. 



JAMAICA PEPPER, or AIj'LSFICE. — 3fyrtus Pimento.. 

 This is a good carminative and cordial, and may be given in 

 doses from half an ounce to an ounce, in flatulency of the 

 stomach and bowels. It may also be used as an ingredient in 

 cordial medicines. 



The following tincture is strongly recommended by INIr. 

 Bracy Clark, as an excellent remedy for the flatulent colic, 

 gripes, or fret. 



Jamaica pepper 1 lb. 



Proof spirit 6 pints. — Mix. 



Let the allspice be powdered, and mixed with the spirit ; the 

 bottle to be well corked, and frequently shaken. In two or 

 three weeks the tincture will be fit for use. The dose, abovit 

 four ounces diluted with water, and repeated every hour until 

 the horse is relieved. See Cordials and Carminatives. 



JAMES'S POWDER. — PwZi;?-^ JacoU. Though the pre- 

 paration of this medicine has been hitlierto kept secret, there is 

 no reason to doubt its being composed chiefly of antimony, and 

 nearly the same thing as that which is sold in the shops by the 

 name o^ Antimonial Powder. (See Antimony.) I can venture 

 to assert that, as a horse medicine, this is as useful and efficacious 

 as James's Powder. It is said to be an excellent medicine in 

 fevers of every kind : and, though usually given in the small 

 dose of a scruple, or half a drachm, may be exhibited with per- 

 fect safety and better effect in a much larger quantity. I never 

 give less than two drachms, and sometimes three ; and I have 

 seen even one ounce given at a dose without the least incon-
