The idea has been suggested that
in certain well-known conditions of
hysteria judiciously administered
pinch of snuff might have beneficial
effect. Familiar to every one is the
perverseness with which such hyster-
ical attacks resist ordinary remedies,
and it seems not improbable that some
of them might be curtailed by period
of vigorous sneezing.
The growth of the orange industry
in Florida has increased from a produc-
ton of 600, 900 boxes in 1855 to 5000, 900
for the season just closed, and accord
ing to conservative estimates the COM
ing crop will be fully 5000, 900 boxes, of
which over 4, 200, 900 will be marketed.
The average price received by growers
the past season was S1.3l per box

1t is announced that a remarkable
new Medara, or jelly fish, has been
found to occur in Lake Tanganyika,
Africa a 'fresh-water" lake, though,
we believe, the water is slightly brack-
ish. 1t is entirely different from the
Jelly fish found living few years ago
in the Victoria Lily-tank of the Kew
Gardens, at London, and represents a
distinct family whose exact position
is unknown.
Analysis of the air, water and soil
of Spitzbergen has brought to light the
extraordinary poverty of these regions
in bacteria. While the air of the
streets of Paris contains on an average
81 900 bacteria, that of the Arctic Sea
contains only three per cubic meter.
As to the water of Spitzbergen, not
only is it devoid of any pathogenic
micro-organisms whatever, but all ba-
cilli are absent. Popular Science News,
Another most valuable series of in
designations in regard TO the metal
best adapted for the construction of
bridges has been made by the Austrian
Society of Engineers. Some 216 me-
chanical tests were made by the COM
mittee having the matter in hand to
determine the quality of wrought iron,
of basic, Bessemer and basic open
hearth steel, the conclusion being that
the latter excels all the others in re-
sistance to mechanical attack and dis
tortion.-N. Y. sun.
In the human body there is said to
be more than 100000 perspirat ton
glands communicating with the sur
face by ducts having total length of
some ten miles. The blood contains
millions of millions of corpusclcs, each
q structure in itself. The number of
rods in the retina, supposed to be the
ultimate recipient of light, is esti-
mated at 50, O00.0 900. A German scien-
fist has calculated that the gray mat
ter of the brain is built of at least $780,
900. 900 cells.
The cough or puff of railway
engine is due to the abrupt emission of
waste steam up the chimney. When
moving slowly the coughs can, of
course. be heard following each other
quite distinctly but when speed is put
on the puffs come out one after the
other much more rapidly, and when
eighteen coughs second are produced
they cannot be separately distinguished
by the ear. A locomotive running at
the rate of nearly seventy miles an
hour gives out twenty puffs of steam
every second that is, ten for each of
its two cylinders.
Nocturnal creatures are generally

light, but facts collected are gradually
dispelling the idea. 1t is well known
that felines, which see well by night,
seem to be able to see quite as well by
day, and this is being found true of
many other creatures. The bat sees
admirably by daytime, as any one can
ascertain by threatening it with a
twig. The owl. also, has first-rate day
sight Night-hying Lepidoptera, when
disturbed in their places of refuge dur
ing the day, have no difficulty in seeing
at once where is the nearest and best
places for a temporary refuge.-N. Y.

Septic tonsilitis." sort of diph.
theritic sore throat. has been very
prevalent in London just lately, and
the suggestion is made that the wood
pavements are the cause of the dis
ease. The vegetable fiber of the wood
absorbs great deal of matter that no
surface cleaning can remove and the
water carts produce on the streets
solution of manure and other impure
ties. In the recent spell of hot weather
this has been converted into dust and
blown into the eyes, noses and throats
eff the public. The only suggestion OF
q remedy is to sprinkle the streets with
water and disinfectant.
If we look intently at bright star
we notice that the color and intensity
of the light is constantly changing
from brilliancy to almost total obscur-
ity, and from bright red to blue
orange, yellow, etc. This is the pk.-
nomenon usually spoken of as the
''twinkling" or scintillation of the
stars. The 'twinlling" will be no
ticed more plainly when the star is
near the horizon. and will diminish in
intensity as it rises until it is near the
zenith, at which time the twinkling is
scarcely noticeable. l. must be con-
fessed that this twinkling has never
