Infusion of the Bark.
To an ounce of the bark, in powder, add four or five table-spoonfuls of brandy, and a pint of boiling water. Let them infuse for two or three days.
This is one of the best preparations of the bark for weak stomachs. In disorders where the corroborating virtues of that medicine are required, a tea-cupful of it may be taken two or three times a-day.
