THE IMPROVED ART OF FARRIERY. 535 



The foregoing preparations are not strictly sulphurs ; 

 vhey contain a considerable quantity of the metallic 

 part of the antimony, which is reducible from them by 

 proper fluxes. 



These preparations must of course be liable to 

 great variations in point of strength, and in this re- 

 spect they are perhaps the most precarious, though 

 some have affirmed that they are the most certain 

 of the antimonial medicines. They prove emetic when 

 taken in the human stomach, in a dose of from four 

 to six grains ; but they are scarcely prescribed with 

 this intention, being chiefly used as alterative deob- 

 struents, particularly in cutaneous disorders. 



Tartarised Antimony. 



Take of crocus of antimony, powdered, one pound 

 and a half; crystals of tartar, two pounds, distilled 

 water, two gallons ; boil in a glass vessel, about a 

 quarter of an hour, filter through paper, and set aside 

 the strained liquor to chrystalise. 



Emetic Tartar. 



Take of the butter of antimony what quantity you 

 choose, pour it into warm water, in which as much 

 of the purified vegetable fixed alkali has been pre- 

 viously dissolved, that the antimonial powder may be 

 precipitated, which after being well washed, is to be 

 dried. Then, to five pounds of water, add, of this 

 powder, nine drachms ; of chrystals of tartar, beat 

 into a very fine powder, two ounces and a half; boil 

 until the powders are dissolved. Let the strained
