Excerpt from The American Journal of Pharmacy, 1866, Vol. 38: Published by Authority of the Philadelphia College of Pharmacy Secondly. A neutral solution of citrate of bismuth, obtained by means of citrate of ammonia and ammonia, or by ammonia alone, of such strength that a fluid drachm contains one grain of teroxide of bismuth, is prone to decomposition. This change is not attended by the deposition of a basic salt, but by the forma tion of humus the liquid acquiring, meanwhile, a disagreeable smell and taste, which totally unfit it for use. This is prevented by the addition of alcohol, whereby it is preserved indefinitely. A concentrated solution appears to keep well without this addition of spirit.
