SCIENTIFIC TOPICS.

From what is now known of radium,
DR.. S. G. Trhcy reaches these conclu-
sions: The discovery may make it neces-
sary to change our theories about matter
and the conservation of energy Radium
may possibly open up the way for
cheaper and moro wholesome lighting of
houses by phoSphorescence. 1t is prac-
tical agent to differentiate genuine gems
from artificial. 1t is a useful agent to
kill bacteria. 1t may be considered a val
liable agent for the treatment of lupus.
cancer tuberculosis. and a possible agent
to improve the eyesight and overcome
blindness Later discoveries will doubt
less show service in other diseased condi

The existence of oscillatory electric cur
rents and discharges is shown in a beau
tiful way by A. Winklemann. The appa-
ratus consists of two vertical VACUUM
tubes, connected by cross tube. the tons

glass support In the center OF one hub
and one OF scheelite in the other Cathode
rays cause the frst-named mineral to
shine with red light and the other to
take blue color. When current is
passed the cathode is shown by the shin
ing Of the mineral under it, and both
minerals shine out when the current is
oscillating. For showing the Transition

pulled so far apart that no oscillations
take place, but both crystals shine out
when the rods are near enough to let
sparks pass.
