95. _Process 2._--Dissolve two drachms of acetate of lead, in six
ounces of water; filter the solution, and pour it into a clean wide
phial. Then suspend a granule of zinc, by a thread or wire fastened to
the cork of the phial, in the middle of the solution, and place the
phial where it will not be disturbed. After a few hours the lead,
being de-oxydized by the zinc, will be precipitated on the zinc, in
the shape of leaves, which will have a very brilliant appearance.


96. TO TIN COPPER BY BOILING.--Boil half a pound of granulated tin,
and six ounces of super tartrate of potass in three pints of water;
when they have boiled half an hour, put in any piece of copper ware,
and continue the boiling fifteen minutes longer. The copper may then
be taken out, and will have been handsomely coated with tin.


97. A METAL THAT WILL MELT IN HOT WATER.--Melt together eight parts of
bismuth, five of lead and three of tin. This alloy, though hard and
brilliant, when cold, is so easily fusible that it may be melted on a
paper, being held over the flame of a candle. Tea spoons may be made
of this compound metal, which may be melted by putting them in a cup
of hot tea.


98. ILLUSTRATION OF CALICO PRINTING.--It frequently occurs, that
substances of different colours, or even without colour, by coming in
contact, produce colours very different from that of either of the
ingredients when separate; thus, if a sheet of paper be striped in one
direction with a hair pencil dipped in a solution of sub-carbonate of
potass; and then crossed with a solution of sulphuric acid, diluted
with five times as much water, it will be colourless; but dip it in a
mixture of a weak solution of sulphate of iron, and infusion of nut
galls, and it will instantly become a beautiful plaid; the ground
being purple, striped one way with black and crossed with white. If a
similar paper be striped with sub-carbonate of potass, and crossed
with infusion of galls, and afterward dipped in a solution of sulphate
of iron, it will become purple, yellow, black and white. Dip a piece
of white calico in a cold solution of sulphate of iron and let it dry.
Then imprint any figures upon it with a strong solution of colourless
citric acid, and let this dry also. If the piece be then well washed
in warm water, and afterwards boiled in a decoction of log-wood, the
ground will be dyed either a slate or a black colour, according to the
strength of the metallic solution, while the printed figures will
remain beautifully white. Stain some parts of a sheet of paper a
purple brown, with a mixture of infusion of galls and sulphate of
iron; stain other parts green with a mixture of tinctures of turmeric
and litmus; stain other parts purple with juice of red cabbage; other
parts red with tincture of litmus and muriatic acid; other parts
yellow with tincture of turmeric; wash the remainder of the sheet with
a solution of sulphate of iron, which will remain white. Then print,
