Dr Rosenthal advocates the use of glycerin as a medium for the solution of various substances used for subcutaneous injection. The glycerin must be very pure. By gradual elevation of temperature it can be made to take up a large number of certain alkaloids and salts, and will retain them dissolved for a year. 1 fl. dr. will dissolve one scruple of sulphate of quinine, and 10 gr. of hydrochlorate of morphia. Dr Rosenthal states that the injection of quinine has been found very useful in intermittents.
