SCIENTIFIC MISCELLANY.

for thoroughly studying tornado phenom-
ena. The work is now carried out by
about 500 observers, called tornado re-
porters, whose stations are mostly located
in the States of Alabama, Georgia, South
Carolina, North Carolina, Missouri, Ar
kansas, Kansas, Illinois, Indiana, LOVE,
Nebraska, Wisconsin aud Minnesota.
Since March 10, 1884, according to
Sergt. J. 7. Finley, tornado predictions
have been made matter of daily study.
The average up to June LIST shows that
it has been possible on fity-iive days to
successfully predict from the morning
weather map that no tornado would oc-
cur on that day; on twenty-eight other
days tornadoes were predicted for partic-
ular States or large regions, and Of them
the tornadocs on seventeen days occurred
in or near the specified region, while on
eleven days tornadocs occurred in regions
for which they were not predicted.
At the London Health Exhibition Mr..
Francis Cation has established labora-
tory for the measurement Of human
faculty. Each visitor will leave a record
Of name, age, sex, occupation, place Of
birth, color Of hair and eyes, height stard-
ing and sitting, weight, length Of span
Of arms, strength Of squeeze and pull,
swiftness Of direct blow, capacity of chest,
acuteness Of vision, conditions Of color
sense, and acuteness Of hearing, and will
take away duplicate. Mr.. Gallon re-
CARDS the art of measuring human facul-
ties as the dawn of new and interesting
science.
According to DR.. A. Berghaus, the
nettle was formerly extensively employed
in Germany for woven fabrics and its use
il being revived. The common singing
nsttle may be made into good yarn, but
the Chinese nettle gives the best results.
A black rain, the coloring matter be-
ing carbon, lately fell in Shropshire,
England.
At recent meeting Of the Physiolo-
gical Society Of Berlin, Prof Busch
called attention to the fact that carries Of
the teeth appears to be peculiar to man,
y it has been observed in no other ami
nal. 1t is not, however, a characteristic
Of civilized man alone, as it has been
seen throughout large collections Of skulls.
even 10 those Of prehistoric time. Some
races arc more disposed to it than others,
the Celtic, Arabian and Polish races be-
ing but little affected with uusound teeth.
Certain families are particularly prcdis-
posed to carries. General habit Of body
and certain diseases have great influence
upon It's development Teeth with un-
dulating enamel have much less power
Of resisting carries than those whose sur
face is quite smooth. As is well known,
diseased teeth are rendered practically
sound BY removing every particle Of car
ions substance and covering tho sound
dentine with protective coating Of gold

Dr.. Albrecht, Of Neuchatel, has been
experimenting to determine the effect Of
methodic Limitations Of oxygen gas upon
the Development Of tubercular .consump-
ton. Loss Of weight was checked in the
consumptives, difficulty Of breathing was
diminished, and an apparent decrease was
caused in the number Of the bacteria
which always accompany the disease. 1t
was his hope that the oxygen nigh, total.
y destroy the bacteria, or supposed cause
Of the malady, and thus effect cure.
Probably large majority Of scientific |
men connect the remarkable suurises and
sunsets Of last year with the volcanic erup-
tion Of Krakatoa. This fact gives espec-
III interest to recent letter from Mr..
3. Nelson, F. r. A. s., stating that the
brilliant sunsets were seen by him in
Natal In February, 1883, more than six
months before the eruption Of the Javan
volcano.

have been made to introduce the insects
