Gum chewers' paralysis is the latest
form, of professional neurosis recorded in
medical literature.
The new telescope for the Harvard OBJ.
scrvatory has been completed and will be
used for photographing stars.
Some interesting experiments have
lately been undertaken at Cherbourg,
France, to ascertain the possibility of teie-
phoning between topedo boats and the
admiral's ship, SO that orders can be
given direct.
The smokeless powder intended for
use in the Austrian army is now declared
to be perfect. Beside the initial advan.
tage of being smokeless, it is said to give
. velocity some twenty per cent. greater
than that of ordinary powder.
A Brazilian inventor has devised
method of keeping soup plates and other
article in their places on board ship in
rough weather. This is, to have the
plates fitted with an iron foot, and an
electro-magnet fitted into the table keeps
the plate in position.

been made privately in Austria with /.
new explosive, probably of the nature Of
melinite, prepared by an officer, Lieuten-
ant Kubin. 1t is called "ecrasite,'' and
Is said to be very powerful, and at the

atmospheric influences.
A German scientist wishes to deter
mine by means of photography If the
moon is inhabited, and it is said that the
King of Wurtemberg has decided, in
order to solve this interesting problem,
to cause to be made, in the best possible
condition, photographs Of the moon;

M. de Susini, Corsican doctor, has,
1t is asserted, constructed motive ap-
paratus or propeller of twenty-horse
power, which is worked by sulphuric
ether, a result which the doctor antici-
pates will realize saving of sixty-fve

Ayoung German student of Assyriology
has been experimenting with soft tiles
and stylus, and concludes that the As
syrians wrote their cuneiform lines with
q cube-shaped instrument having a
pointed end, which was made of wood,
not metal. He processes to find it very
easily to write cuneiform as rapidly as
German with such stylus.
It is calculated that a range of mount
aims consisting of 176 cubic miles of
solid rock falling into the sun would
only maintain the heat for single Sec
ond. A mass equal to that of the earth
would maintain the heat for only ninety
three years, and a mass equal to that Of
the sun itself falling into the sun would
afford $4,000, 900 years of sun heat
Professor Hirschberg declares in a
viennese medical paper that Professor
Ebers, the well-known novelist, has
rendered great service to medical sci
ence by the discovery, translation and re-
production in facsimile of part of q val
liable MS. containing medical recipes
used in Egypt and written about 1900
years before Christ. The portion trans
lated and annotated by Ebers treats of
diseases of the eye. 1t is the Oldest med
ical treatise now known.
A peculiar tendency in idiots to imper-
fections and disease in the teeth has been
noticed by several physicians; and it has
been studied by Madame Sollier in hun
dred cases of idiots taken at random
The multiplicity and variety Of the dem
tai lessons were remarkable; and the con-
clusion has been drawn that idiocy, with
or without epilepsy, predisposes to arrests
of development and to anomalies of denti-
ton. The effect rarely appears in the
first teeth, however, but almost wholly in
the second.
