534 THE IMPROVED ART OF FARRIERY, 



powder, the metallic part of the antimony, in a state 

 of calx, will be united with that part of the hartshorn 

 which is indestructible by fire ; viz., an absorbent 

 earth. If this powder be properly prepared, it is of a 

 white colour. It is a mild antimonial preparation, and 

 is given as an alterative. 



Precipitated Sulphur of Antimony. 



Take of antimony, powdered, two pounds; water 

 of pure kali, four pints ; distilled water, three pints ; 

 mix, and boil them with a slow fire for three hours, 

 constantly stirring, and adding the distilled water as 

 it may be wanted ; strain the hot ley through a double 

 linen cloth, and drop into the hot liquor, by degrees, 

 as much diluted vitriolic acid as is sufficient to pre- 

 cipitate the sulphur. Wash off, with warm water, the 

 vitriolated kali 



Golden Sulphur of Antimony. 



Boil, in an iron pot, four pounds of caustic ley, 

 diluted with three pints of water, and throw in, by de- 

 grees, two pounds of powdered antimony, keeping 

 them continually stirring with an iron spatula for 

 three hours, over a gentle fire, and occasionally sup- 

 plying more water. 



The liquor, loaded with the sulphur of antimony, 

 being then strained through a woollen cloth, drops into 

 it gradually, while it continues hot, so much spirit 

 of nitre, diluted with an equal quantity of water, as 

 shall be sufficient to precipitate the sulphur, which is 

 afterwards to be carefully washed with hot water.
