Camphorated Julep.
Take of camphor, one drachm; gum arabic, half an ounce; double-refined sugar, an ounce; vinegar, a pint. Grind the camphor with a few drops of rectified spirit of wine, till it grows soft; then add the gum, previously reduced to a mucilage with equal its quantity of water, and rub them together till they are perfectly united. To this mixture add, by little and little, the vinegar with the sugar dissolved in it, still continuing the trituration.
In hysterical and other complaints where camphor is proper, this julep may be taken in the dose of a spoonful or two as often as the stomach will bear it.
