struetion is to be tried at Paris for
teaching pupils the pronunciation of
difficult words in foreign languages.
All ordinary fruit acids are said TO
act upon tin, and one cas- is reported
in which persons were made violently
sick from eating fruit preserved in tin
cans, no foreign substance except tin
being found in the fruit.
Sir Wyville Thompson has estimated
that the pressure upon a mans body at
a depth of 1900 feet beneath the
surface of the sea would be equal to a
weight Of twenty locomotives each with
a good train loaded with pig iron.
Excavations commenced a short dis
lance from the walls Of Pompeii, with
q view of a~scertaining the nature Of the
surroundings ofthe city have led to the
discovery, within an area OF a few
square yards, of thirty skeletons, ten
of which were huddled together in one
| room of q small SUBURBAN yilla;brace-
let's, earrings and other objects, were
found upon the bones.
A writer in the Jeoih World points
out that, contrary TO the received idea,
the elder Rabbins OF the Talmnd taught
that the world was round. This Is
shown by a passage in which, in dis
cussing idolatry, the figures holding In
the hand a baton, a bird, or a globe
were prohibited, because the baton
~sym5olizes the dominion Of the world
the bird that the world lies beneath 1t.
and the globe is forbidden because 1t
resembles the form of the world itself.
According to the studies Of N. Hebert
the storms which reach the European
coast from America originate, for the
most part in Mexico, Central America,
and the northern parts of South Amer
lea; but they do not generally strike
the Atlantic until after they have
traversed a more or less extended part
OF the length OF the North American
continent. The storms which originate
in the United States reach Greenland,
or pass the neighborhood Of Ireland or
the Farce Islands too far away to affect
Europe.
A curious experiment in heat Is per-
formed with an apparatus devised by
DIR. Grassi. The apparatus consists of
three concentric vessels separated by
annular spaces of about three-fourths
of an inch. The outer space is filled
with oil, and the inner with water.
The oil Is heated to a point above 2l2
degrees Fahrenheit, when the water
begins to boil. Oil heated to 5000 is
then introduced into the central vessel,
aud falls rapidly to a temperature about
that of the boiling wator. DIR. Grassi
finds that this central oil cools the
more quickly the greater heat Of the
outer ring Of Ola result seemingly
| very paradoxical.
In a paper on the organs of smell in
insects, Gustav Hauser describes several
interesting experiments. Numerous
species of insects, on approaching YES
sells containing turpentine, or acetic
acid, showed-by ~retreating and NOV
ing their antennae-a distinct percep-
ton Of the smell. After the ends Of
the a~ntennae have been cut of, the
same insects placed close to the vessels
appeared quite insensible TO the odors.
A number Of flies, which had been at
tracted by a piece of pu:rid meat
showed no inclination to approach II
after portions Of the ~antennae had been
cut of.
The death was lately announced OF
Mr.. F. A. Nobert, whose fine rulings
on glass have given him a world wide
celebrity. As test plates for the power
of microscopes he ruled bands of lines
of varying aneness from II 200 to
LIZ 900 to the English inch. 1t was
formerly his opinion that lines 80 fine MS
the 1-1l2, 0o0th of an inch would never
be seen resolved in the microscope.
This feat was accomplished, however,
by DR.. Woodward; when Mr.. Naberi
Immediately produced a new plate, hay
ing one band of lines of a Aneness Of
224 900 to the English inch. Whether,
or not these minute lines will ever be
seen cannot now be safely predicted.
Mr.. Nobert has been very reticent In
regard to his methods, and 1t is thought
probable that no one is acquainted with
the secret of his success. 1t may there
fore befall us that Nobert's microscopic
ruling is to be counted among the ''lost
arts."
The presence Of dlsagreeable odors In
the atmosphere was the source Of con-
siderable annoyance to people in GER
tam districts of Paris last summer
The smells were found to originate In O
certain establishment where refuse
matter is manufactured into fertilizers
NJ. Bouchardat, Of the Paris medical
faculty, has examined the question o.
the effect OF these emanations upor
health, and has concluded that they are
innocent. He does not believe that
they convey with them the germs Of
disease, and finds that the gases Of
which they are composed does not load
the air enough to produce a perceptible
poisoning. Assuming that contagiou:
diseases should manifest themselves
within eight or ten days after the
planting Of the germs, the weekly
health bulletins of the year have been
examined to learn IL any increase OF
