Preparation.—"Fresh yolk of egg, forty-five grammes (45 Gm.) [1 oz. av., 2,57 grs.]; glycerin, fifty-five grammes (55 Gm.) [1 oz. av., 411 grs.]; to make one hundred grammes (100 Gm.) [3 ozs. av., 231 grs.]. Rub the yolk of egg, in a mortar, with the glycerin, gradually added, until they are thoroughly mixed. Then transfer the mixture to a bottle"—(U. S. P.).
This preparation is of a honey-like consistence and is of value as an emulsifying agent for cod-liver and other oils. If kept from contact with the air, so that it can not absorb moisture, it keeps unaltered for a great length of time.
Action and Medical Uses.—Protective and emollient. Useful in burns, erysipelas, erythema, and other cutaneous irritations for which glycerite of starch is employed. It is inferior to that agent for most purposes.
