Mix the arrow-root with half a gill of cold water, and pour this into a small saucepan containing nearly half a pint of boiling water, the sugar, and the wine; stir the arrow-root while it is boiling on the fire for a few minutes, and then give it to the patient.
Observe that it is essential to perfection in the preparation of arrow-root, and, indeed, of all farinaceous kinds of food, that the whole of the ingredients used in the preparation should be boiled together.
