COAL TAR PRODUCTS.
That a coal-tar product should find a de-
mand among pharmacists. farmers as We'll
as In surgery and dyeing, is remarkable,
but such is the case with naphthaline,
one Of the latest manufactures from coal
tar. a German chemist has discovered that
one Of the most striking characteristics Of
naphthaline is the fact that it is not in

organisms, both animal and vegetable,
such as fungi. insects. etc, for they are
not able 10 endure the action Of the gas
for any length of time. These. however.
are the very properties that a good anti
septic ought to possess 1t is now used
as a protection against moths by fur
dealers and others. and is also useful in
Kidding houses of other insect pests. For

That a sweetening agent should come from
coal tar will be a surprise to many but
such is really the case BY a novel treat
ment of one of the cSmpOnents of coal tar
a compound may be obtained possessing
very similar sweetening properties 10 the
lest cane or beet-root sugar. The sac
charine presents the appearance of white
powder, and crystallizes from it's aqueous
solution i'm thick. short prisms. soluble in
warm water Saccaharine forms salts. all
of which possess a very sweet taste, and
physicians are looking TO this product as
a substance by means Of which diabetic
persons may enjoy food which has hitherto

gas in the making of which coal tar is a
refuse and a species of sugar obtained
from that refuse are probably such a COM

has given us that term.
In the great cotton plantations of the
Southern States cotton seed was for gen.
erations thrown away. but II IS now a rec

blending of lubricating and cooking oil in
the mixture OF feed cakes for cattle. Oil
ropes, after they have been picked by
prisoners, are served up again as material
for caulking ships. The refuse from candle
works comes out as glycerine, and that of
soap works as manure. Some of the most
delicately scented perfumery comes out
of waste rubbish. Use has been found
for the refuse of tanneries and curriers'
shops. Much OF the material formerly
wasted in these trades is now used for

The saying that an enterprise has AL
ended IN smoke does not have the signif-
canoe that IL did before a way was found
90 materialize that airy product into sub
stances as tangible oils. acids. spirits
and tar. a single blast furnace in a West
ern State which captures the smoke of it's
charcoal pits and conveys il into stills, has
been able TO realize enough from this
source 10 pay large share of its running
expenses. 1t has demonstrated that each
cord OF wood contains $4,000 cubic feet of
smoke. and that 100000 feet of smoke pro-
duces 1900 pounds of acetae of lime and
200 gallons of alcohol and twenty-five
pounds Of tar. Smoke from the factory
chimneys is largely carbon in another form,
and in the course OF few years we may
expect to see some diminution of the smoke
nuisance so prevalent in large towns. not
from the vigilance OF the sanitary inspec-
tors. but because consumers are beginning
20 learn that. instead OF allowing the par
ticles OF carbon 10 escape with the other
products. helping 10 poison themselves
and their neighbors. they might have light
or coal bills to pay by burning up these
particles.
