Sulphate of barium ... } weight in substitu-
Mica ... ... } tion for an equal
Talc ... ... } amount by weight

HERCULES POWDER No. 3.—Consisting of not more than 40 parts by weight of thoroughly purified nitro-glycerine, uniformly mixed with and absorbed by 15 parts by weight of a mixture consisting of 66·5 parts by weight of purified wood-pulp and 33·5 parts by weight of purified starch, such nitro-glycerine, wood-pulp, and starch being further mixed with not more than 45 parts by weight of purified nitrate of soda. The whole to be sufficiently absorbent in quality when mixed in the above proportions to prevent exudation of nitro-glycerine.

LANITE.—Consisting of nitro-cotton, carefully washed and purified, combined with thoroughly purified nitro-glycerine, with the addition of aniline not exceeding half per cent. by weight of the finished explosive, and calcium carbonate or magnesium carbonate not exceeding 1 part by weight in every 100 parts by weight of the finished explosive.
