Lemoine recommends morning and
night rinsing of the mouth with a
glassful of so grams of Labarraques's
solution diluton with one liter OF
water, and spraying the nasal pas
sages and throat with an ordinary tot
let atomizer containing some such SOL
ution as J gram of phenolsalyl and 3
grams of table salt in 500 grams of dis
titled water. A few menthol drops
may be carried in the pocket and dis
solved in the mouth occasionally. 1t
is by such means, this author tells US,
that many extremely sensitive persons
keep the upper air passages in an anti
septic condition, and through it they
have been able to pass the winter and
rainy spring without once taking cold.
The pigment in the human skin has
been a recent subject of investigation
by NJ. Breul, who finds the coloring
matter to be distributed in patches in
the interior of the epithelial cells, the
tissue between the cells being colorless
even in black races. The pigment it.
self may be quite black, or of any
shade up to light yellow. The differ
enee in the color of races depends upon
this difference in the shade of the pig
ment, the distribution of the coloring
matter being the same in all races, and
the actual amount probably the same.
What is claimed to be an incombust-
ible celluloid-a product greatly desir-
eds made by NJ. Asselot by mixing
solution of part of celluloid in 10 of
acetone with a solution of 2 parts of
magnesium chloride in 6 of alcohol.
When the paste is dried an uninfiam-
mable celluloid remains.
A laboratory for the study of cave
animals has been established in some
subterranean passages lately found un-
der the Jardin des Plantes, Paris.
1t was about twenty years ago-in
1877 or 1878-that astronomers were
startled by the sudden appearance in
the equatorial belts of Jupiter of a
marking of such unusual size aud
depth of color that it has heen known
since as the Great Red Spot. Though
remarkably persistent, this spot has
not been seen lately, its place showing
a very light color. A recent discussion
by the British Astronomical Associa-
ton reveals tendency to regard this
spot, however, as permanent feature
of the planets solid surtace-a kind of
Sahara desert or dry region, one astron-
omer contended, surrounded by a
cloudy region, while another supposed
it to be an elevated portion of the body
of the planet. Observations by Cassini
indicate that the spot had been seen
two centuries ago, although no men-
ton was made of its color. Some fif-
teen or eighteen years ago the whole
equatorial region of Jupiter was of an
orange color, with no white portions in
it, though previouslyit had been nearly
white for some years, and this tends to
confirm the idea that the uuclouded
planet is of warmish hues of varying
depth.
The singular action of certain metals
and other substances on Photographic
plates has been described to the Royai
Society by Mr.. w. j. Russell. Not
only do uranium salts and oxides act
slowly on sensitive plates in the dark,
but the property is shared by metallic
zinc, cadmium and magnesium, as well
as by copal, strawboard, wood, some
kinds of paper, and other substances.
The action was at first thought to de-
pend on contact, then it was supposed
feeble emanations might be given off.
Neither superstition proves to be true,
however, for zinc acts equally we'll
when not in contact with the plate,
and even when vanished.
After trial of two years, DIR. J. A.
Bridges reports that the best treatment
for sprains known to him is the appli-
cation of electricity once day for five
to seven days, with massage for five
minutes twice day.
The venom of bees-claimed to be a
remedy for cancer, snake-bite, and 9TH
er ills-is now regularly collected by
two young pharmacists. The bees are
held singly by the abdomen in a small
glass tube or enraged together in a
bottle until the tiny drops of poison
are discharged.
Some interesting experiments on the
effects of weather on plants are given
in little work by Mr. John Clayton,
an English naturalist. Twelve beam
plants were placed in the ground so
that one-half of them would receive all
the sunshine of the day while the 9TH
ers remained continuously in the shade.
and the crop of beans grown in the sun
shine weighed three times that pro.
duced in the shade. The experiment
was continued in succeeding years.
All seeds were planted under the con-
ditions of the preceding year, the diff
ferences between the two classes of
plants progressively increasing until
In the fourth year the plants of exclu-
slvely shade-grown ancestors lowered
but failed to mature fruit. Measure
ments of the contraction of trees in
winter were also made. The girths of
sycamore trunks were from two to
three sixteenths of an inch, and of
oaks from five to six sixteenths of an
inch, less in February at temperature
of 30 Fair. than in October, after
growth had ceased, and the trunks had
expanded to their original size on
March 2nd, at temperature of 800
The frequent splitting of forest trees
is due to this contraction by cold.
