The most expensive thermometer
in this country is in use in the Johns
Hopkins University. 1t is known as
Prof. Rowland's thermometer, and is
valued at $4,000. 1t is an absolutely
perfect instrument, and the graduations
on the glass are so fine that it is neces-
sary to use microscope to read them.
An excellent and abundant substi-
tute for India rubber is reported as hav-

Great anxiety is felt in Switzerland
concerning the decadence of the watch
making industry, which, next to the
textile industry, is the mainstay of the
inhabitants of the country. The profits
are dwindling down, as the United
States and England are every year be-
coming more powerful rivals in this
field. The demand, too, for Swiss
watches is falling off considerably in
certain countries, notably in this coun-
try and in France.
Prof. Dana concludes that during
the glacial period Long Island sound,
instead of being, as it now is. an arm of
the ocean twenty miles wide, was for
the greater part of its length narrow
channel, serving as common trunk for
many Connecticut streams and a few
from Long Island In these circum-
stances the supply of fresh water FOR
the Sound river would have been so
great that salt water would have barely
passed the entrance of the sound.
Mrs. Carrie Williams, silk cultur-

of japanese. direct from Toxic, has
purchased tract of land in San Diego
county, California, and will engage in
the industry. San Francisco has a
Woman's Silk-Culture society, the only
one in the United States.
Not long ago Prof. Tillmans, of
Leipzig, performed the unique surgical
feat of removing lung which had be-
! come hopelessly diseased. The patient
recovered, not only the operation, but
from the disease, and in a few months
had lost the appearance of an invalid to
such an extent that DR.. Tillmanns
failed to recognize him when he called.
Sir Morril Mackenzie says that this case
seems to open up great possibilities for
the combination of Koch's treatment
with surgery.-Rochester Herald.
The new industry of camphor pro-
duction gives promise of being per-
manently established in Florida. 1t is
believed that in ten years time there
will be more camphor trees than orange

that of sugar. 1t is stated that the
camphor obtained from the Florida trees
approaches more nearly to that of Japan
than to Chinese camphor, since the odor
of safro is distinctly recognizable

DR.. Uspensly, of st. Petersburg,
has just laid before the Hygienic So
ciety there, as well as the Russian min
lister of the interior, an account of his
method and success in treating con-
sumption. He claims he is able to cure
it. He uses the Brown-Sequard elixir

resist the disease, and then completes
the cure by means of prescribed diet
and mode of life. Heincludes in his ac-
count large number of testimonials,
written by men who say they were
cured by him and bearing the endorse

David Livingstone, that keen and ac-
