are safer and more effective antidotes in phosphorus poisoning, as too 

 large doses of copper sulphate are required for this purpose. 



CuPHi AcETAs. Copper Acetate. (Non-official.) 



Synonyms. — Verdigris, cupric subacetate, E.; ac§tate de cuivre, vert-de-gris, 

 F.; griinspau, G. 



Derivation. — Exposure of copper plates to pomace or residue resulting from 

 expression of juice from grapes in wine making, or to immersion in pyroligneous 

 acid. 



Properties.- — Pale-green masses of minute, acicular crystals, sometimes of 

 bright blue hue. Verdigris is the impure article; the pure salt is known as 

 Crystals of Venus. The taste is coppery and odor vinegar-like. Soluble in water. 



Dose.—H. & C, gr.ia-30, (1-2); Sh. & Sw., gr.5-10, (.3-.6). 



Action External. — It is astringent, stimulant and escharotic accord- 

 ing to the strength whether applied to the unbroken skin or to mucous 

 membranes or raw surfaces. 



Action Internal. — This salt is an efficient vermifuge for the expul- 

 sion of ascarides from the horse. It should be given in doses of gr. 15-30 

 (1-2- Gm.) twice daily with powdered gentian and charcoal, 1 dram of 

 each (4.0 Gm.), for a week and then be followed by a cathartic dose of 

 aloes. It is a poison in large doses, causing gastro-enteritis, convulsions 

 and death. The antidotes are milk, raw eggs and soap. 



Bismuthum. 



(Bismuth is not employed medicinally in the metallic state.) 

 BiSMTJTHi SuBCARBONAS. Bismuth Subcarbouate. (BiO)2COj-|-H20? (U. S. P.) 



Synonym. — Bismuthi carbbnas, B. P.; carbonate of bismuth, bismuthyl carbo- 

 nate, E.; sous-carbonate de bismuth, Fr.; wismutsubcarbonat, basisches kohlen- 

 saures wismutoxyd, G. 



Derivation. — Made by dissolving pure metallic bismuth in diluted nitric acid, 

 precipitating with ammonia water, and redissolving in nitric acid. This solution 

 is treated with ammonium carbonate, or a solution of sodium carbonate. 



2Bi (NO,)a+3 Na,C03-|-H,0=(BiO)2 C08-hH,0+2 C0,+6 NaNOa- The 

 precipitated bismuth subcarbonate is filtered and washed. 



Properties.— A white, or pale yellowish-white powder, of somewhat varying 

 chemical composition; odorless and tasteless, and permanent in the air. Insoluble 

 in water or alcohol, but completely soluble in nitric or hydrochloric acid, with 

 copious efflorescence. 



Dose.—H., 3ii-iv, (8-15); D., gr.x-xxx, (.6-2). 

 Bismuthi Subnitras. Bismuth Subnitrate. BiO NOj-l-HjO.' (U. S. & B. P.) 



Synonym.— Bismutura subnitricum, P. G. ; bismuthum hydriconitricum, magis- 

 terium bismuthi, E.; subazotas (s. subnitras) bismuthicus, sous-azotate de bismuth, 

 Fr.; basisches salpetersaures bismutoxyd, G. 



Derivation. — Dissolve pure metallic bismuth in diluted nitric acid. First re- 

 action— Bi,-j-6 HN03 = 2 Bi (N03)3-|-3 H^. Final reaction— Bi (N03)3+H30 = 

 BiON03-j-2 HNO3. Evaporate; add water; wash and dry precipitated bismuth 

 subnitrate. 



Properties. — A heavy, white powder of varying chemical composition; odor- 

 less and almost tasteless, and sUghtly hygroscopic in the air. Almost insoluble 

 in water, insoluble in alcohol, and readily dissolved by nitric or hydrochloric acid. 



Dose. — Same as subcarbonate. 



Bismuthi Subsalicylas. Bismuth Subsalicylate. (U. S. P.) 



Dose.—D., gr.iv, (.24). 



Bismuthi Subgallas. Bismuth Subgallate. (U. S. P.) 



Synonym. — Dermatol, E.; sous-gallate de bismuth, Fr.; wisrautsubgallat, G.
