SULPHUR 197 



largely employed in connection with diseases of the nose, ear and throat 

 to arrest pain after operations, and in ulceration and inflammation of 

 these parts, as sore throat. Nasal gleet in horses should be benefited if 

 not cured by the insufflation of the powder. Orthoform is commonly used 

 in ointment containing 10 to 20 per cent, of the drug. It may be blown 

 pure into cavities or applied as a saturated solution in collodion. It may 

 be sprayed on a part with an atomizer in 5 per cent, solution with equal 

 parts of alcohol and water. It has been injected into the bladder in 

 cystitis mixed with water. In ulceration of the stomach, orthoform will 

 give relief owing to its local anesthetic action. It may be administered 

 mixed with water and syrup in the dose of 0.5-1.0 (7^-1 5-gr.) for dogs. 

 It is an expensive drug at present.

 Sulphur. 



Officiai/ Varieties. 



Stjlphur Subumatum. Sublimed Sulphur. S. (U. S. & B. P.) 

 Synonym. — Flowers of sulphur, floras sulphuris, E.; fleur (cr6me) de soufre, 



Fr. ; schwefelblumen, schwefbluthe, G. 



Derivation. — Obtained from native sulphur by sublimation. 



Properties. — A fine, yellow powder, having a slightly characteristic odor and 



a faintly acid taste. Insoluble in water; slightly soluble in absolute alcohol; 



soluble or partially soluble in carbon disulphide, olive oil, benzine, benzol, oil of 



turpentine and many other oils; also in ether, chloroform, and in boiling, aqueous 



solutions of alkaline hydrates. 



PHEPARATIOSrs. 



Sulphur Latum. Washed Sulphur. S. (U. S. P.) 



Synonym. — Sulphur depuratum, flores sulphuris loti, P. G. ; soufre lavS, Fr. ; 

 gereinlgte schwefel, G. 



Derivation. — Obtained from sublimed sulphur, which is treated with diluted 

 ammonia water to wash out sulphurous and sulphuric and other impurities. 



Properties. — A fine, yellow powder, without odor or taste. Solubility, same 

 as sublimed sulphur. 

 Pulvis Olyeyrrhizw Gompositus. Compound Powder of Glycyrrhiza. (U. S. P.) 



Senna, 180; glycyrrhiza, 236; washed sulphur, 80; oil of fennel, 4; sugar, 500. 



Dose. — Dogs (laxative), 3ss-i, (2-4). 



Unguentum Sulphuris. Sulphur Ointment. (U. S. & B. P.) 



Washed sulphur, 160; benzoinated lard, 850 (U. S. P.) 



Sulphur Prcecipitatum. Precipitated Sulphur. S. (U. S. & B. P.) 



Synonym. — Lac (magisterium) sulphuris, milk of sulphur, E.; soufre pr6- 

 cipit§, lait de soufre, Fr.; schwefelmilch, G. 



Derivation.— Obtained from a solution of sublimed sulphur, 100; in boiling 

 calcium hydrate, 60; by precipitation with hydrochloric acid. Calcium sulphide 

 and hyposulphite are formed. 12 S+S Ca OjH^ = 2 Ca S^+Ca S, O3+3 HjO. 

 Then: 2 CaS^+Ca S^ Os+fi H CI = 3 Ca 01^-1-12 S-|-3 H^O. 



Properties. — A fine amorphous powder, of a pale yellow color, without odor or 

 taste. Solubility same as sublimed sulphur. 



Dose (of sublimed, washed or precipitated sulphur). — H. & C, §ii-iv, (60- 

 120) ; Sh. & Sw., 3i-ii, (30-60) ; D., 3ss-iv, (2-15). 



Larger doses laxative; smaller for constitutional action. 



Precipitated sulphur is the best preparation for internal use, as it occurs in 

 a finer state of division and is more readily acted upon by the digestive juices. It 

 may contain traces of sulphides or sulphureted hydrogen, owing to the method 

 of preparation.
