1t is said that successful trials of
telephone apparatus without wire
have been had in Italy. The instru.
ments were installed on moving trains.
The details of the experiments and
apparatus are very meagre.
Three s'cures' for tuberculosis are
at present competing for professional
favor in Italy-two of them, that OF
Cervello of Palermo-and that OF
Ruata of Perugia, consisting of medi.
Gated inhalations, and the oldest OF
them, that of Maragliano of Genoa,
proceeding by sero-therapy.
Emile Camis has exhibited before
the Paris academy of medicine an ap.
pliance to obyiate the danger of pre-.
mature burials; it consists of lever
and spring, by which any movement
or struggle by the buried person sets
signal and starts an automatic alarm.

Mountain toothache is a new addi.
tion to our bodily ills. 1t has attacked
engineers and laborers on the Jung.
frau railroad at height of $500 feet
above sea-level as a jumping toothache
that attacks several teeth at time,
lasts seven or eight days and leaves
the patient with swollen face, which
it takes another week to reduce. After
that, the teeth are acclimatized and
give no further trouble.
A somewhat novel form of rail joint
has recently been introduced on a
Western railroad. It is a base-sup.
port joint located between ties, and
comprises in addition to angle bars on
either side of the rails fastened to.
gether by four bolts, short piece OF
rail inverted and placed under the
joint. This piece of rail is fastened
to f1anges of the angle bars by U-bolts.
Three of these bolts are used in some
cases and two in others, the presence
of the middle bolt having not yet been
proved absolutely necessary.
For many years efforts have been
made from time to time to measure
the heat radiated from some of the
brightest stars. The most successful
attempt appears to be that of Profess
sor Nichols at the Yerkes observatory.
With the aid of an apparatus recalling
the principle of the Crookes radiome
ter, he has ascertained that the star
Vega, which shines very brilliantly
near the zenith in midsummer even
ings, send to the earth an amount of
heat equal to that of an ordinary can
die six miles distant Arcturus, the
star celebrated by Job, and which has
a somewhat fiery color, radiates about
twice as much heat as Vega.
An explanation of fog has recently
been given by Professor Barr of the
University of Glasgow, who says that
it was once commonly believed that
the particles composing fog or
cloud consisted of small vessels OF
water filled with some very light gas.
This explanation was given to account
for the suspension of these particles,
but the manner in which the bubbles
or vesicles were formed, end the in.
clusion OF a gas lighter than air, and
other circumstances quito obvious
were never made plain. Very small
particles of water have tendency to
fall slowly in still air, while a very
slight upward current will be enough
to keep them from descending at all
in the case of very small particles.
1t has been shown that the glotules
of water forming a fog or cloud are
each composed of film of water con-
densed upon particle of dust, and
the cores are solid instead of gaseous,
as the old theory indicated.
