ates. The same chemists have now
studied meteorltes, finding gallium in
varying proportions In meteorlc irons,
but not In all meteorltes. a little
rubidium also exists In the irons. The
chief points OF difference between the
meteoric and terrestrial irons are found
to be that the former contain much
nickel and cobalt with only minute
traces of manganese. while the ordln.
airy iron ores contain manganese with
only traces of nickel and cobalt. Sodi-
UNI and potassium occur in meteoric
irons in small proportions. Meteoric
irons, like iron ores and manufactured
irons, contain copper, lead and silver.
meteoric stones, unlike meteorlc irons
contain chromium and manganese.
The West indies are threatened with

A similar reproduction of a modern

Three kinds of electric telegraphy
across space are recognized by Prof.
| Silvanus =. Thompson-those depend
/ ing respectively on conduction, Undue
ton and wave methods. The last kind
| has been employed by Prof Slaby of
| Charlottenburg in sending Ineligible
Morse signals 1917 miles. balloons be-
| ing used to raise the end conductors
| 1000 feet in the air The signals were
thus transmitted about 20 times the
| base line, but Marconi. in experiments
| at SpeZia, has sent them 800 times the
length of the base line. Prof Oliver j,
Lodge has taken the first steps toward
synchronizing the transmitting and
receiving Instruments, causing them
| to respond only to waves of the period
| to which they are turned. Prof.
/ Thompson believes we may develop
the condition or induction methods so
as to communicate between England
and India or Cape Colony much more
| cheaply than by submarine cable, but
doubts whether-on account OF the
| earths curvature-it would be prac-
ticable to cover such distances by any
| wave method.
