    former oxide of antimony, have nevertheless discovered that oxide of antimony may be procured from emetic tartar : and, combined with the repetition of Dr. Powell's “additional information/' that 10 grains of it may be exhi¬ bited, it is truly a dangerous preparation. This substance is now directed to be made by decomposing a solution of tartarized an¬ timony with carbonate of ammonia; which is not a good precipitant, because a portion of it combines with the antimonial salt, and forms a soluble quadruple compound ; conse¬ quently a part both of the alcali and oxide are wasted: even after long ebullition, and the addition of more ammonia than is directed, sulphuretted hydrogen throws down a copious orange - coloured precipitate. This circum¬ stance is however of but little consequence, as I am persuaded that this preparation will never be much employed. There is no good autho¬ rity for attributing to it any advantages not possessed by tartarized antimony; and the evidence against its use is very decided. Dr. Powell persists in representing it as similar to almost every oxide of antimony, however dif¬ ferent from it and from each other, which has been introduced into the various editions of the Pharmacopoeia, from the year 1720, to the present time.
