In paper on the organs !of smell in in
sects, Gustave Hauser describes several in
teresting experiments. Numerous ccies
of insects, on approaching vfssels contain
ing turpentine or acetic acid, showed-by
retreating and moving theif antenu@-a.
distinct perception of the smell. After
the end of the antenne had been cut of,
the same insects placed close to the ves-
sells appeared quite insensib4e to the odors.
A number of flies, which had been at
tracted by piece Of putrid meat, showed
no inclination to approach it after portions
of the antenna had been cut off,
A curious experiment id 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 filed wiah 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
800 degrees is then introduced into the
vessel, and falls rapidly to,a temperature
about that of the boiling water Dr.
Grassi finds that this central oil cools the
more quickly the greater tie heat of the
outer ring of ola result seemingly very
paradoxical
The death was lately announced of Mr..
r. \. Nobert, whose fine rulings on glass
have given him Worldwide celebrity
As testplates for the power of micro
scopes he ruled bands of lines of varying
fneness from IL 200 to iI2,0o0 TO the
English inch. 1t was formerly his opinion
that lines so fine as the l-lI ,O00th Of an
inch would never be seen resolved in the
microscope. This feat was accomplished,
however, by DR.. woodward; when Mr..
Nobert Immediately produced new plate,
having one band Of lines If fneness of
$4,000 to the English inch Whether
or not these minute lines wall ever be seen
cannot now be safely predicted. Mr.
Nobert has always been very retieent in
regard to his methods, and it is thought
probable that no one is acquainted with
the secret Of his success. 1t may there
fore befall us that Nobera's microscopic
ruling is to be counted among the g lest
arts"
The presence of disagreeable odors in
the atmosphere was the source of consid-
erable annoyance to people in certain dis
tricts of Paris last simmer. The smells
were found to originate in d certain estab-
lishment where refuse matter is manufac-
tured into fertilizers. NJ. Bouchardat, of
the Paris medical faculty, has examined
the question of the effect of these emana-
tions upon health, and has concluded that
they are innocent He does not believe
that they convey with theEa the germs Of
disease, and finds that the giasses Of which
they are composed do not load the air
enough to produce perceptible poison
ing Assuming that contagious 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 10 learn if any
increase of mortality followed the intro
duction of the edors. Nc such increase
has been detected.
Trouve's utilization of electricity in
combination with surgieaE instruments is
bearing fruit. A case is.reported from
Vienna in which a doctor has succeeded
in curing cancer in the stomach, mainly
through the assistance rendered by the
polyscope in Illuminating, the cavity Of
the stomach. The electric probe, which
rings a bell when ball or metallic sub
stance imbedded in the muscles is reach
ed, is found valuable acquisition by
army surgeons; and an application of the
same principle to surgical forceps has en-
abled Berlin oculist to save mechanics
eye which had received Fit of steel The
case had become so urgent that the eye
must be lost unless the peice of metal
could be extracted withaut delay; bat
DR.. Hirschberg, by inserting soft iron
probe and subsequently converting it into
a magnet by passing an electric current
through it, withdrew the metallic particle,
and saved the eye.
