---England imports annually about
$4,000 teas of palm oil, but 1t is con-
sidereS that this is a very small amount
compared with what might be the case
were the enormous supplies fully or
even moderately realized.
Recent investigation has shown
that the amount of tannin which is the
noxisus element in tea, is from three
times to five times as great in tha Ben
gal and Ceylon leaf as in the Chinese.
The attention of the medical profession
in America is called TO this fact
We are nation of coffee drinkers.
During the last nine months the inn
ports of coffee into the United States
amounted to 4G5, 1877, 732 pounds, an in
crease of upward of 100000, 900 pounds
over the imports for the same period
last year. In the same time the inn
ports of tea have increased only from
75,6O9, 214 pounds to s3, 27O, ,3O2 pounds.
AT the present time the whole num-
Der of double stars known and recorded
by astronomers is something over 10,-
600, far exceeding the total number of
stars visible to the naked eye in the
entire armament about 5000, and
others are being frequently discovered
by the great telescopes now in existence.
DR. PIE Smith says of the gout,
that not all drinks will produce it, for
t is rare in Scotland. Not all wines
will produce it, for it is rare in Spain
and Italy. Not all malt liquors will
produce it, for it is rare in Vienna and
Munich. But it belongs to the most
civilized times and nations, to the
stronger sex, to the most vigorous
period of life, TO the higher classes of
society and to the most able.
Near Baltu the center of Russian
petroleum industry, is witnessed the
anomaly of water used for steam pur-
poses costing more than fuel. The
water is bad and dear, selling for about
fifty cents ton, while ton of astatl1i,
which is the residuum of the distilla-
tion of naptha, and is the combustible
naturally utilized, is sold at a price
equivalent to thirty-six cents per ton of
coal.
Long distance photography is rem
dered quite successful by a new camera
with telescope objective, which con-
sists of concave lens of short focus
and convex lens of considerable length
of focus. These are put at a certain dis
tance apart, depending on the differ
ence of the two foci BY the laws of
optics this arrangement projects an in
verted image of an object at a long dis
tance from the lenses.
Brazil with 3,210,O0O square miles
and 14,OOO,OO0 people is the United
States of South America. Her foreign
trade is now s315, 200, 900, about equally
divided between exports and imports.
England sells Brazil s47 100000 worth
of goods annually and buys only 5,000,-
900. The United States last year took
from Brazil $50, ,233, $50 worth of coffee,
rubber, sugar, hides and skins. We
sold to Brazil S14,710,9 955 worth of our
products, but this is double the amount
sold four years ago.-St. Louis Globe

Sound travels by waves radiating
from a central point of disturbance,
just as waves raullUe Wnen SUOne is
dropped into still water. So far as the
hearing of each individual is concerned
these waves move in direct line from
the cause of the sound to his ear, the
impact being the greatest in the ear
nearest the source. This being the case,
a person who has totally lost the sense
of hearing in one ear, although he may
imagine that the defect is of little con-
sequence, cannot locate the direction of
a sound to save his life even when the
center of disturbance is quite near.
