Saline Mixture.
Dissolve a drachm of the salt of tartar in four ounces of boiling water; and when cold, drop into it spirit of vitriol till the effervescence ceases; then add, of peppermint-water, two ounces; simple syrup, one ounce.
Where fresh lemons cannot be had, this mixture may occasionally supply the place of the saline julep.
