This may be effected by changing the order of their arrangement, which can only be ascertained by a previous examination of a key chosen for that purpose.
No. XLIV.
To make a key of a chamber door, which to your sight hath its wards and rose-pipe but paper thick, and yet at pleasure, in a minute of an hour, shall become a perfect pistol, capable to shoot through a breastplate, commonly of carabine proof, with prime, powder, and fire-lock, undiscoverable in a stranger's hand.
NOTE.
The rose-pipe must in this case be formed like the sliding tubes of a telescope; that next the wards being furnished with a screw at the inner and capable of holding the whole of them together. A small quantity of detonating powder being first placed within, the pipe may be readily discharged by tightening of the screw.
No. XLV.
How to light a fire and a candle, at what hour of the night one awaketh, without rising or putting one's hand out of bed. And the same thing to be a serviceable pistol at pleasure; yet, by a stranger, not knowing the secret, seemeth but a dexterous tinder-box.
