(1873)
“ To effect the explosion of this compound a tube or cap containing fulminate of mercury or other suitable detonating substance, and affixed to the end of a fuse, is inserted in the charge of the above-described compound, the fuse being fired in the usual way, or, if preferred, the cap inserted in the compound may be fired by electricity without a fuse. ”
