The idea has been suggested that
in certain well-known conditions OF
hvsteria a iudiciously administered
pinch of snuff might have benehcial
effect. Familiar to every one Is the
perverseness with which such hyster-
zeal 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 $500, QUO
for the season just closed. and accord
ing to conservative estimates the COM
ing crop will be fully 5000, 900 boxes, OF
which over 1000, 900 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
ielly fish found living a 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
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 Id 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 te
be more than 100000 perspiratior
glands communicating with the sur
face by ducts, having total length Of
} some ten miles. The blood contains
4 millions of millions of corpuscles, eacf
t a structure in itself. The number O.
rods in the retina, supposed to be thu
: ultimate recipient of light, is esti
t mated at 30,000,00o. A German scien
S fist has calculated that the gray mat
Y ter of the brain is built of at least 600,
r 600, 900 cells.
The cough or puff Of railwa.

waste steam UP the chimney. Whel
