No. IX.
Reading edition
An engine, portable in one's pocket, which may be carried and fastened on the inside of the greatest ship, tanquam aliud agens, and, at any appointed minute, though a week after, either of day or night, it shall irrecoverably sink that ship.
NOTE.
To prepare this dangerous instrument, it is merely necessary to connect a gun-lock with a common bomb shell, filled in the usual manner, and a small clock attached; which will at any given time discharge the lock, and cause the shell to explode: the tremendous effects of which in the cabin or hold of a vessel may easier be conceived than described.
