"Logwood, in chips, 50 grammes; Cinnamon Bark, bruised, 10 grammes; Distilled Water, sufficient to produce 1000 millilitres. Boil the Logwood with twelve hundred millilitres of Distilled Water in a suitable vessel for ten minutes, adding the Cinnamon Bark towards the end of the time; strain; if necessary pour sufficient Distilled Water over the contents of the strainer to produce the required volume." Br.
We prefer the old U. S. formula, which ordered an ounce of the logwood to be boiled with two pints down to a pint, and doubt much whether the wood is exhausted by a boiling of ten or fifteen minutes. The cinnamon of the Br. formula is in general a very suitable addition, but there might be circumstances under which it would be better omitted, and in this case, as in others, any addition to the simple decoction might be left to the judgment of the prescriber.
