Per cent. Phosphorus, 1·4 Flowers of sulphur, 42·2 Flour, 42·2 Sugar, 14·2 ------ 100·00 Three common receipts give the following proportions:-- Per cent. Phosphorus, 1·5 Lard, 18·4 Sugar, 18·4 Flour, 61·7 ------ 100·00 Per cent. Phosphorus, 1·2 Warm water, 26·7 Rye flour, 26·7 Melted butter, 26·7 Sugar, 18·7 ------ 100·00 Per cent. Phosphorus, 1·6 Nut oil, 15·7 Warm water, 31·5 Flour, 31·5 Sugar, 19·7 ------ 100·00 A very common phosphorus paste, to be bought everywhere in England, is sold in little pots; the whole amount of phosphorus contained in these varies from ·324 to ·388 grm. (5 to 6 grains), the active constituent being a little over 4 per cent. Matches differ much in composition. Six matchheads, which had been placed in an apple for criminal purposes, and were submitted to Tardieu, were found to contain 20 mgrms. of phosphorus--_i.e._, ·33 grm. in 100. Mayet found in 100 matches 55 mgrms. of phosphorus. Gonning[276] analysed ten different kinds of phosphorus matches with the following result:--Three English samples contained in 100 matches 34, 33, and 32 mgrms. of phosphorus: a Belgian sample, 38 mgrms.; and 5 others of unknown origin, 12, 17, 28, 32, and 41 mgrms. respectively. Some of the published formularies are as follows:-- [276] _Nederlandsch Tijdschr. voor Geneesk._, Afl. i., 1866. (1.) Glue, 6 parts. Phosphorus, 4 „ or 14·4 per cent.
