Some interesting parlor experiments
with the metal tin are thus described
by technical journal: A candle, blow
pipe and tin foil are necessary. With

candle against a strip of tin foil, and

a brilliant light, the melted incandes-

was observed many years ago that this

than the original tin. This simple OBJ
servation was the beginning of the long
series of investigations which finally led
to the discoveries of Priestley, Scheele,
and LayOisier, and laid the foundations
OF the modern science of chemistry.
An ingenious German, says the En-
cheering Magazine, has invented a pro-
cess for removing the element of smoke
from the combustion of coal, and that
by an entirely different principle from
any of those before known. The tests
are said to have been very satisfactory,
and contracts have been entered iuto
with several large manufacturing con-
Germs. The coal is first finely powded-
ed by special machinery and is then in
jected into the furnace by an automati
cally regulated current of air. The car
bon is entirely consumed, there is no
smoke and no ash is precipitated. The
fire is under perfect control and can
be started or cut off at moments
notice.
A new kind of paint, notes the Age
of Steel, is announced, which, it is
claimed, possesses in a peculiar degree
from rust, and is unaffected by either
heat or cold. When applied to sheet
iron it is found that the coating is
not affected by warm water or steam
nor is it at all influenced by the action
of acid and alkaline liquids, ammonia
gas, hydrOchOlOric acid gas and sui
phurated hydrogen gas. The principal
ingredient in this paint is a silicate of
iron which is found in the nighbor-
hood of natural deposits of iron ores,
and also occurs in veins in deposits of
granite, which have become decompOsed
by contact with the air.
In order to be certain, in rail mills,
of always saving off the rails at prac-
tically the same temperature, so as to
insure uniform rail lengths after cool
ing, some foreign makers, according to
the Revue Industrielle, use colored
glasses, through which the rails at
certain temperature become invisible.
They can be cut at that particular mo-
ment and the object thus attained.
A clever chemist has invented a
novel thermometer. 1t is in the form
Of a sensitive paint, which, at the or
binary temperature, is a bright yellow,
but, if submitted to heat. gardually
changes color until at 22O degrees f.
it shows a brilliant red. On being
cooled it returns to it's pristine hue,
but remains as sensitive to heat as ever
In one of the Comstock mines a new
water wheel is to be placed which is
to run 1850 revolutions a minute, and
have a speed at it's periphery of 1O,SO5
feet per minute. A greater head of wa
ter than has ever before been applied
to a wheel will be used.
An electric acid meter, or instrument
for measuring the amount of acid sub |
stance in liquids, has recently been
perfected, and is expected to come into
extensive use in refineries, breWeries
and many similar establishments.
