2?S VIL EARTHS AND ALKALIES.— 



alkali is obtained in unluted vessels than in luted. Hales says, 

 subcarb. of ammonia heated absorbs air. 



Rectified bone spirit. Salt ofhones^ Sal ossiiun. The rough 

 Spirit, distilled from l-8th of wood ashes, or charcoal powder ; 

 the salt of bones first arises; when it begins to melt by the spirit 

 that succeeds, the distillation is stopped for the present, the salt 

 taken out, and then distillation begun again, till nearly the whole 

 of the liquor has come over. 



• Spirit of urine, Spiritus urince, Salt of urine. Obtained 

 largely from urine which has been kept a little while ; for if fresh, 

 the water must be distilled off before the spirit will appear. 



Spirit of wood soot, Spiritus fuliginis^ Salt ofiuood soot, Sal 

 fuliginis. From wood soot ; strongly scented, anti-epileptic. 



Liquid mild volatile alkali, Spirit of sal ammoniac, Spi- 

 ritus salis ammoniaci, Aqua ammonice, P. L. Aqua carbonatis 

 ammonice. Subcarb. of potash 31b., sal ammoniac J<Jlb., water 

 Sib. ; distil to dryness. 



LiauoR AMMONiJE CARBONATIS, Liquor ammouicB suhcarho- 

 natis. Subcarb. of ammonia 3iiijj distilled water lb. j ; dissolve 

 and filter : stimulant, gtt. xx to 3j, also as an errhine. 



Henry's carbonate of ammonia-water. Dissolve subcarbonate of 

 ammonia in water, so that the sp. gr. may be 1*046 : two mea- 

 sures are equal in saturating acids to one of his carbonate of 

 potash-water. Used in analysis. 



Ammoniacal liquor. From coals.; obtained in those gas- 

 works that use coals; a chaldron yielding about 200 gallons. 

 Used to make sal ammoniac. 



Caustic volatile alkali, Spirit of sal ammoniac with lime. 

 Aqua ammonioi puree. Lime, water ana lb. ij ; slake and add 

 sal ammoniac lb. j, boiling water lb. vj, cover the vessel imme- 

 diately ; when cold pour off the liquor, and distil with a gentle 

 heat lb. j. 



Aqua ammoni.^ caustics. Lime lb. ij, water lb. j, slake 

 and cover it up: the next day add sal ammoniac 3xvj, water 

 lb. v, distil 5xxj. The specific gravity ought to be -934 ; or a 

 bottle holding Jxij of water should hold 3xj — 3iijss of this fluid. 



Aqua ammonia, P. E. Lime lb. jss, water ^ix, slake, when 

 cool add sal ammoniac lb. j ; distil into distilled water lb. j, until 

 the retort becomes red hot. 



Liquor ammonite. Lime 3vj, water lb. j ; slake, and cover up 

 for an hour, then add sal ammoniac Jviij, boiling water lb. iij, 

 and cover till cold, then strain and distil oxij. Specific gravity 

 should be '960 ; or a bottle holding Sxij of water should hold 

 Sxjss of this fluid. This is seldom given internally — externally,
