and then to add as much water as is requh'cd. This last sohi- 

 tion is much stronger than any other. A sohition of sublimate 

 in spirits of wine or diluted hydrochloric acid, is employed with 

 advantage for coagulating the synovia as it escapes from open 

 joints, so as to afford a temporary plug to the opening. 



SUBMURIATE OF MERCURY.— Hi/drarrji/ri Suhmv- 

 rias. New name, Protochloiiide of Mercury. — Hijdrargyri 

 Chloridum. See Calomel. 



SUCCINUM. See Amber. 



SUDORIFIC S. Medicines that cause sensible perspiration 

 or sweating. In the horse there is no medicine that will, with 

 certainty, produce this effect, and it is only by exercise or warm 

 clothing that it can be produced. In locked-jaw a horse has 

 been kept in a state of perspiration for a considerable time by 

 being covered with sheep-skins. Vinegar and acetate of am- 

 monia will sometimes cause perspiration ; and opium, with eme- 

 tic tartar, camphor, and cordials, is said to have a sudorific 

 effect ; also ipecacuanha, with opium, camphor, and salt of 

 hartshorn. [Spirit of nitrous ether will more frequently produce 

 a sudorific effect than any other medicine, particularly if joined 

 with camphor. — Ed.] 



SUET, MUTTON"; BEEF.— ^t'w«« Ov Ilium ; Bovimnn. 

 Prepared suet is used in the composition of ointments and 

 plasters. Suet boiled in milk has been recommended in the 

 scouring rot of horned cattle. 



SUGAR OF LEAD. Acetate and Superacetate of Lead. 

 — Saccliarum Saturni. Plumhi Acetas et Superacctas. See Lead. 



SULPHATE OF AUJUl^ A. — Alumince Sidphas. See 

 Alum. 



SULPHATE OF COPPER.— C«/;W Sulphas. Blue vi- 

 triol, or Blue stone. This preparation of copper is much used in 

 veterinary practice as an external application ; it is a mild caustic 

 or escharotic, and, when dissolved in water, forms a good detei*- 

 gent or astringent lotion. The addition of a little sulphuric, 

 nitrous, or muriatic acid to this lotion increases its streno;th as 

 a detergent, and, when the proportion is considerable, makes it a 

 strong caustic. A solution of sulphate of copper in vinegar, or 

 vinegar and water, makes a good wash for the foot rot in sheep. 

 Sulphate of copper should be finely powdered when sprinkled 

 on ulcers, or when mixed with lard or other unctuous matter 

 into an ointment. When a solution of sulphate of copper is suffi- 

 ciently diluted, it may be used as a mild astringent, and, when 

 very weak, may be applied even to the eye. Sulphate of copper 

 has been given internally as a tonic in diabetes, and in farcy: the 

 dose, from half a drachm to a drachm.* 



* ]\Ir. Sewell recommends sulphate of copper, in closes of three to six 

 drachms with linseed meal, in the form of a draiight for glanders. Thus
