Wafers of Tamarinds.
Take Tamarinds 1 ounce; them in a Mortar with thin Mucilage of Gum Dragant, pass them thro' a pulping Sieve, dissolve also Spanish juice of Liquorice in the same sort of Mucilage 2 drams; mix, and make Troches as thin as Wafers to seal Letters; which dry in an Oven, according to art.
These are very pretty desirable and useful things to hold in the Mouth, to alleviate Thirst, and take away an ill Taste in Fevers.
