240 VI. METALS —Oxides of. 



water, to which Uh. of oil of vitriol and lib. of common salt has 

 been previously added : decant the clear solution and pour it 

 into hot water, wash and dry. 



OxTDUM a:ntimonii nitro-muriaticum. Mur. acid 3XJ, 

 nitric acid 5j, common antimony oij, dissolve, pour the clear solu- 

 tion into a gallon of water, and wash. 



OxiDUM ANTiMONii, P. L. 1815. Dissolve emetic tartar 51] 

 in distilled water, and subcarb. of ammonia 5ij in another portion 

 of water, mix the two solutions, boil till the precipitation is com- 

 plete, and wash the precipitate. 



Peroxide of antimony, Diaphoretic antimony^ Antimonium 

 dlaphoretlciim, Calx antimonii, Antimonium calcinaiam. Common 

 antimony lib., purified nitre olb., inject by spoonsful into a red 

 hot crucible, powder and wash ; the flowers that stick to the 

 side of the crucible must be carefully separated, otherwise they 

 render it emetic; comp. of 5*5 ant. with 2 oxyg., equiv. 7*5. 



Bezoar mineral, Bezoarticum minerale. Upon butter of 

 antimony drop slowly as much nitric acid, distil it off, and pour 

 it on again, adding one-third fresh acid ; repeat this operation, 

 and calcine the residuum. 



Magistery of diaphoretic antimony, Materia perlata. 

 To the water that was used in washing the diaphoretic antimony 

 add spirit of vitriol, or some other acid, as long as any precipitate 

 is produced, which is to be washed. 



Cerussa antimonii. Regulus of antimony 21b., purified 

 nitre 3lb. : grind together, and proceed as for diaphoretic anti- 

 mony; produce 2lb. 13oz. In this operation and similar ones, 

 the admixture of the emetic flowers may be avoided by sink- 

 ing the crucible deep in the coals, so that the sides, up to the very 

 top, may be too hot for them to settle on ; or they may be collected 

 by using a tubulated earthen retort. 



Calx antimonii nitratis. To 4oz. of regulus of antimony, 

 finely powdered, add by degrees 12oz. of nitric acid, distil to 

 dryness; powder the mass and wash it. — Diaphoretic, in doses of 

 gr. ij to X ; but Wilson, Course of Chemistry, p. 106, says he 

 has known diaphoretic antimony given with good success by half 

 an ounce at a dose, and repeated two or three times a day, and 

 that for several days successively. 



Flowers of antimony, Flares antimonii. Throw into an 

 ignited tubulated retort powdered common antimony by spoons- 

 ful, till as many flowers come over into the receivers as are wanted : 

 the bottom of the retort must be very hot, and the fire kept up 

 steadily ; emetic, in doses of gr. j to ij. 



Argentine flowers of antimony, Flares antimonii argcntei.
