Let the almonds be blanched, and beat up in a marble mortar; adding the water by little and little, so as to make an emulsion; afterwards let it be strained.
Arabic Emulsion.
This is made in the same manner as the above, adding to the almonds while beating, two ounces and a half of the mucilage of gum arabic.
Where soft cooling liquors are necessary, these emulsions may be used as ordinary drink.
Camphorated Emulsion.
Take of camphor, half a drachm; sweet almonds, half a dozen; white sugar, half an ounce; mint-water, eight ounces. Grind the camphor and almonds well together in a stone mortar, and add by degrees the mint water; then strain the liquor, and dissolve in it the sugar.
In fevers, and other disorders which require the use of camphor, a table-spoonful of this emulsion may be taken every two or three hours.
Emulsion of Gum Ammoniac.
Take of gum ammoniac, two drachms; water, eight ounces. Grind the gum with the water poured upon it by little and little, till it is dissolved.
This emulsion is used for attenuating tough, viscid phlegm, and promoting expectoration. In obstinate coughs, two ounces of the syrup of poppies may be added to it. The dose is two table-spoonfuls three or four times a-day.
