Measure a quart of boiling water, and set it away to get cold. Take one-third of a six cent loaf of bread, slice it, pare off the crust, and toast the crumb nicely of a light brown. Then put it into the boiled water, set it on hot coals in a covered pan, and boil it gently, till you find by putting some in a spoon to cool, that the liquid has become a jelly. Strain it through a thin cloth, and set it away for use. When it is to be taken, warm a tea-cupful, sweeten it with sugar, and add a little grated lemon-peel.
