Tie up a quart of wheat flour in a pudding-bag, tightly. Put it into a pot of boiling water, and keep this boiling for several hours (all day or all night will not be too long). Then take out the flour and dry it near the fire. Peel off and throw away the thin outer portion, and grate down the mass, with a nutmeg-grater, into a powder, for use as wanted. One or two teaspoonfuls of this may be rubbed into a paste with a little milk, and then stirred into a pint of milk, which is to be scalded; that is, just brought to the boiling-point, without being boiled. This is often beneficial in the diarrhoeas of infants or older persons.
