ill deaden the brightest colors in the room, and
the dresses of the company will seem to be changed. Let each one put
his face behind the flame, and it will present a most ghastly spectacle
to those who stand before it. This is serviceable in tableau where
terror of death is to be represented. The change wrought by the flame,
when the materials are properly prepared, is very surprising.

3. Wet a piece of thick wrapping paper, then dry near the stove. While
dry, lay it down upon a varnished table or dry woolen cloth, and rub it
briskly with a piece of India rubber. It will soon become electrified,
and if tossed against the wall or the looking glass will stick some
time. Tear tissue-paper into bits, one-eighth of an inch square, and
this piece of electrified paper will draw them. Or take a tea-tray and
put it on three tumblers. Lay the electric paper on it, and on touching
the tray you will get a little spark. Let the paper lay on the tray,
and on touching the tray again you will get another spark, but of the
opposite kind of electricity. Replace the paper and you will get
another, and so on.

4. To produce a spectrum, burn magnesium wire in a dark room, and as
soon as the flame is extinguished, let each one try to look into the
other's faces. The spectrum of the extinguished light is clearly seen.

MURIATE OF TIN. TIN LIQUOR.--If druggists keep it, it is best to
purchase of them already made, but if you prefer, proceed as follows:
Get at a tinner's shop block tin, put it into a shovel and melt it.
After it is melted, pour it from the height of four or five feet into a
pail of clear water. The object of this is to have the tin in small
particles, so that the Acid can dissolve it. Take it out of the water
and dry it; then put it in a strong brass bottle. Pour over it Muriatic
Acid twelve ounces, then slowly add sulphuric acid eight ounces. The
Acid should be added about a tablespoonful at a time, at intervals of
five or eight minutes, for if you add it too rapidly you run the risk
of breaking the bottle by heat. After you have all the Acid in, let the
bottle stand until the ebullition subsides; then stop it up with
beeswax or glass stopper, and set it away; and it will keep good for a
year or more, or it will be fit for use in twenty-four hours.
