" Take of socotorine aloes in powder, half an ounce; ex-tract of liquorice, one ounce and a half; alcohol, four owices;water, a pound. Digest for seven days, with a gentle heat, ina close vessel, which is to be frequently shaken (a circumstanceto be attended to in preparing all the tinctures); then pour offthe clear tincture."

This may be regarded rather an aqueous solution than atincture, the quantity of spirit being too small to serve anyother purpose than that of preventing decomposition. It maybe used in the same cases as the extract of aloes; but, notwith-standing the presence of the liquorice, the bitterness of thealoes is so intense and disagreeable, as to prevent it from being' often prescribed. Its dose is from f ^ fs. to f ^jfs.

TINCTURA ALOES .ETHEREA. Edin. EtherealTincture of Aloes.

" Take of socotorine aloes, myrrh, of each, in powder, anounce and a half; English saffron cut, an ounce; sulphuricether with alcohol, a pound. Digest the myrrh with the etherfor four days, in a closed bottle; then add the saffron and thealoes. Digest again for four days, and when the dregs havesubsided, pour off the tincture."

The spirit of sulphuric ether is supposed to afford a moregrateful tincture than spirit of wine; and in cases attendedwith spasm, as in hysteria attendant on obstructed menstrua-tion, this solvent may prove serviceable, independent of thematter it holds in solution. It is a warm stomachic purgative,and is advantageously given in dyspeptic affections, jaundice,gout, chlorosis, and other cases in which alcietics are indi-cated. In doses of f3j. or f$ij. it acts chiefly as a stomachic;but purges briskly in larger doses.
