Preparation.—Take of dogwood bark, in coarse powder, 16 troy ounces; alcohol, 76 per cent, 4 pints; white sugar, 6 troy ounces; water, a sufficient quantity. Moisten the bark thoroughly with alcohol and let it stand 24 hours; then transfer it to a percolator, and gradually add the rest of the alcohol, returning a little of the first that passes till it runs clear.

To the powder in the percolator add gradually cold water, a sufficient quantity, until the liquid that passes is but slightly impregnated with the properties of the dogwood; evaporate this latter solution to 1/2 pint, then add the sugar, continue the evaporation until the syrup is reduced to 8 fluid ounces, and while warm, mix in the reserved tincture and extract, and make 1 pint of fluid extract.
