SCIENCE AND INDUSTRY.

-Colorado's farm products have al
ready run up to $50, ,000,00 a year, its
cattle product to $34, 000,0 900, its coal
product to $50, 900, 900, and its manufac-
turing product to $1,000, 900, though
but tenth of the land is under eulti-
vation, while the entire metal output
of the state, according to the last CEN
sus, was only $50, 900, ,00O.-Boston Her

The idea has been suggested that
in certain well-known conditions of
hysteria a 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 produc-
ton of 600, 900 boxes in 1885 to $4,000
ing to conservative estimates the COM
ing crop will be fully 5000, 900 boxes, of
which over 4, ,OO0,O will be marketed.
The average price received by growers
the past season was S1.31 per box

1t is announced that remarkable
new Medara, or jelly fish, has been
found to occur in Lake Tanganyika,
Africa, ''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.-RopularS Science News,
Another most valuable series of in
vestigations 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 perspiration
glands communicating with the sur
face by ducts, having total length ct
some ten miles. The blood contains
millions of millions of corpuscles, each
a structure in itself. The number of
rods in the retina, supposed to be the
ultimate recipient of light, is esti-
mated at so, 900, ,0O0 A German scien-
tist has calculated that the gray mat
ter of the brain is built of at least 60O,-
900, 900 cells.
Nocturnal creatures are generally
supposed not to see well in the day
| 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 frst-rate day
sight. Night-fying 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 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 wooC
pavements are the cause of the dis
ease. The vegetable fiber of the woot
absorbs a great deal of matter that NJ
surface cleaning can remove and th'
water carts produce on the streets ;
solution of manure and other impuri
ties. In the recent spell of hot weathe,
this has been converted into dust ant
blown into the eyes, noses and throat
of the public. The only suggestion O
remedy is to sprinkle the streets wit
water and disinfectant.
If we look intently at a bright sta
we notice that the color and intensit
of the light is constantly changin
from brilliancy to almost total obscur
ity, and from bright red to blue
orange, yellow, etc. This is the phe
nomenon usually spoken of as tn
''twinkling" or scintillation of th
stars. The ''twinkling' will be NJ
ticed more plainly when the star
near the horizon, and will diminish i
in ensity as it rises until it is near tn
zenith, at which time the twinkling
scarcely noticeable. 1t must be COZ
fessed that this twinkling has neve
been explained to the satisfaction {
all investigators. However, it is gel
orally believedto be due to controllin
causes within the earth's atmospher,
That the cause may be looked fc
within the belt of air that surround
our planet Ito particles of vapor, dus
etc. may be inferred from the fat
that the planets never exhibit tt
