Take Oj of oil of turpentine, and Oiv of water; distil the oil. Thisprocess is seldom necessary, the common oil of turpentine beingusually pure enough.Chemically it contains a volatile oil, which is soluble in hot, but not incold alcohol; it is soluble in ether. It does not combine with alka-lies like the fixed oils.Very pure oil of turpentine has been procured by Dr. Nimmo, of Glas-gow, by agitating eight parts with one part of very strong alcohol,when the alcohol will take up the impurities and float. This ispoured off, and fresh alcohol used till the oil becomes tasteless and in-odorous. It is a pity that it cannot be long kept in this state with-out deterioration.Externally it is stimulant; and with this view it enters into some lini-ments for bruises, &c. Forty drops triturated with ^ss of oil ofalmonds with cotton dipped into it and put into the ear, is good fordeafness arising from inspissated cerumen. (Maule.)Internally it has recently come into repute in many disorders, and itacts differently according to the dose. For worms, and particularlytaenia, or tapeworm, it is the best remedy yet known, in doses of Jssto Jij, floating upon peppermint or cinnamon water, or spring water,with a few drops of oil of lemons, night and morning, till the wormsbe expelled, and if it do not purge it must be aided by castor oil. Ifit cause flatulence and eructation, a little brandy may be given. Itis also useful in large doses, in the obstinate constipation arising fromhydrocephalus and other affections of the brain, and is quite safe. Itis good in epilepsy, yellow fever, melsena, and lately it has had severaladvocates in puerperal fever, lumbar neuralgia, and internal inflam-mations. It acts in small doses as a good diuretic, imparting a violentodour to the urine. It may be given advantageously in doses of1fl_xv to 3J, rubbed up with 5jss of honey and 5X of cinnamon water,thrice a day, in sciatica, lumbago, and other forms of rheumatism andgout. It may also be given in form of enema, with mucilage, forcolic, gall-stones, &c. It is singular that in doses of ^j it will fre-quently excite the kidneys, so as to cause bloody urine, while in dosesof 5 v j or 5j it will scarcely act on the kidneys at all.
