A pit at FeruschowitZ. Sllesia, has
reached a depth Of $500 feet. The tenn
perature Is twelve degrees Cent at the
top and siNty-three degrees at the bot
tom, an increase OF one degree for
every li3 feet Of descent.
The existence Of luminous eNamlna-
lions from the living body has been
demonstrated by DR.. Luys to the Paris
Biological society in the following
manner: In the dark room the
fingers were placed on an ordinary
Photographic plate for about twenty
minutes. the plate being in bath OF
the usual hydroquinone solution, and
the negative was then fixed in the
usual way. Not only are fingers, with
their lines and pours reproduced, but

surrounds each. No result was OBJ

on patients whose hands We're para

The nantes for the Welsbach gas

encountered was the lifting Of toe
