water has been expressed into the in
tercelIular spaces.
If now the temperature be raised
the ice melts first in the intercellular
spaces and gives the familiar wilted
appearance of frozen plant when
suddenly warmed. If, however, the
temperature is very gradually raised
the cell will reabsorb the water as
fast as formed and no injury will re
suit. If the cell contents be complete
ly solidified permanent injury results.
Earth Messages.
Messages may come through the
very center of the globe as well as
around it. The earth is never still.
Tremors, pulsations, rises and falls of
level are always in progress, After
prolonged investigation of these phe-
nomena in Japan, Prof John Milne
has established an observatory at
Newport, in the Isle of Wight. The
days of violent movements are over
,, for the present in that charming re
gion, but the recording instruments
there show constant tremblings.
Four times on an average every min

of vibration run through the world and
round it's surface, and at a large num-
Der of stations where these sensitive
instruments are installed the move

rapidity of vibrations depends on the

feet per second; in solid granite, 1865.
Professor Milne finds that tremors
which have come through the very cen
ter of the earth reach him with such
velocity as to prove that the earth's
interior must be more rigid than a
globe of solid iron. So distinct and
trustworthy are the indications that

What sort of matter fills the interior
Of this planet has long been a subject
of speculation. Lord Kelvin arrived
at the conclusion that the eartn's mass

would raise a tide on it's surface.

Music From the Electric Arc.
A London electrician, Mr.. w Dud-
dell, recently exhibited novel must
cal instrument, composed of a series
of electric arc lights, which played
popular air When the current is
passing through the solid carbons,
they give off musical sound, and by
placing a shunt across the carbons
connected with a keyboard, Mr.. Dud-
dell was able to vary the sounds
through the scale of two octaves. The
keyboard served to vary the self-induc-
ton and capacity in the shunt circuit
and by employing four arcs in series
! the intensity of the sounds was made
sufficiently great.
