it to explode sooner than might be thought agreeable.

FULMINATING

BOOTS & SHOES.

These are prepared by enclosing half a grain of Brugnatelli's Fulminating Silver in a fold of glass paper, and pasting it in the middle of a piece of court plaster; if the edges of the court plaster are then slightly wet, it will adhere, and must be placed in the middle of the heel of a boot or shoe, and by being pressed upon will detonate loudly. Observe, it must be fastened on the outside of the heel.

This experiment may be easily accomplished, while you are left alone, in any apartment where boots or shoes are kept, and would cause a tolerable degree of astonishment to the wearer, on his placing his foot to the ground.

FULMINATING

PIPE LIGHTS.

These lights are made by inserting one-third of a grain of Fulminating Silver, in one end of a piece of hemp-stalk, in the same way as directed for the Segars. A piece of stout deal shaving might be used, prepared in the same manner as directed for the Fulminating Cards. Be careful to notice, that, whatever is used, has some particular mark attached to it, so as to point out which end is to be lighted.

FULMINATING

WALKING STICKS.

These may be made by inclosing half a grain of Brugnatelli's Fulminating Silver in a small fold of glass paper, and putting it into a ferule, which ferule may be placed gently on the stick; and on its being applied to the ground, a loud explosion will take place.

A vast number of other Fulminating objects might be prepared by the same means as here used, as it must have been observed, the Silver detonates either by friction or heat. But great attention must be paid to the quantity of Fulminating Silver used, as very unpleasant consequences might arise from the use of too large a quantity; and on the other hand, no effect produced by too small a quantity; but from one fourth to half a grain will most commonly be found quite sufficient for those purposes that require handling; and here again let me impress it on the mind, how necessary it is to pay attention to the quantities I have here specified for each object: and let me request that it may in no one instance be exceeded.
