These can be procured at the principal grocers and confectioners, or at a chocolate manufactory. They are the thin shells that envelope the chocolate kernel, and are sold at a low price; a pound contains a very large quantity. Soak them in water for five or six hours or more, (it will be better to soak them all night,) and then boil them an the same water. They should boil two hours. Strain the liquid when done, and let it be taken warm.
