Common Black Drop. The celebrated Black Drop, Lancaster or Quaker's Black Drop may be made as follows. Take half a pound of opium sliced; three pints of good verjuice, (juice of the wild crab,) one and a half ounce of nutmegs, and half an ounce of saffron. Boil to a proper thickness, and add a quarter of a pound of sugar, and two spoonfuls of yeast. Set the whole in a warm place, near the fire, for six or eight weeks; then place it in the open air until it becomes a syrup. Lastly, decant, filter, and bottle it up, adding a little sugar to each bottle. One drop is equal to three of laudanum; and it is nearly devoid of all the unpleasant exciting effects of the latter. An analogous formula is contained in the Pharmacopoeia of the United States under the name Acetum opii, Vinegar of Opium.
