In the new nebular hypothesis of
Prof. T.. j. j. See, it is assumed that
spiral nebula was formed by two or
more streams of cosmic dust, which
met in such way as to produce
whirling motion about II central
vortex. This nebula was much larger
than the present solar system, and as
it coiled up under It's own gravitation,
the spirals were gradually drawn
nearer together, and the nuclei formed
in the coils gathered more cosmic
dust, beginning the planets, which at
first moved In elliptic paths of great
eccentricity. The resistance of the
nebula reduced the orbits in size,
giving their present remarkable
roundness. The limits of the Solar
System may be still unknown, for the
orbit of Neptune is almost circular.

great distance from the center, the
nebula offered much resistance OF
moving bodies, and must have had
sufficient density to form several large
planets beyond those now known.
The new process announced by
Consul Olivares, of Managua, is de-
signed to make soft wood proof
against the ravages of the termites, or
white ants,-which in the tropics
often destroy the finest buildings in
six months, and Is specially recon-
mended to makers of furniture and
woodenware intended for use in tropi-
cal countries. or untreated woods
only eucalyptus and teak resist the
termites. The treatment consists in
boiling the newly cut timber in a
sacohariue solution which extracts
the air and coaRulates the albnmen
In the sap. and then rapidly drying
at fairly high temperature. The hard,
homogeneous product-which does
not shrink, warp or spllt-reslsts the
dry rot of temperate lands as we'll as
the tropic termites.
| Titanium is said to be the only
metal suitable for the bearings and
axles of certain modern gasoline
motors, which run at speeds as high
as 1000 revolutions per minute. The
metal is obtained from FUTILE, or
titanium dioXIde, mineral OF little
commercial Importance hitherto.
The fogphone of r. Ii. Marriott, of
Brooklyn, is designed to prevent
collisions at sea by a combination of
wireless telephony and the ordinary
fog bell or the submarine bell, and
it's action depends upon the fact that
the sound of the bell travels in air
about l 1000 feet per second, or slight
ly faster in water, while the trans
mission of the same sound by the
wireless telephone is practically in
stantaneous, or at the rate of light
about 1876, 900 miles a second. AS the
man in the pilot house catches the
sound of the bell in the telephone
receiver, he presses the button that
starts an instrument resembling a
stop watch. When the sound Of the
bell arrives by air or water waves he
stops the instrument and the dial
instead of indicating seconds like the
watch shows the miles and feet the
sound has travelled. at the distance
of two miles the air sound would be
heard about ten seconds after that of
the telephone. When the hell is next
heard, the indicator shows whether
the distance has increased or dimin-
ished, and thus the navigator is mott
fed if there is danger OF collision.
It was decreed by the convention
of 1878 aud the treaty of Washingt on
of 1876 that the boundary between the
United States and Canada from the
Lake of the Woods to the Pacific =
distance of 1870 miles-should
follow the forty ninth parallel. L he
surveyors who have lately completed
the location of the boundary have
found that the astronomical parallel
varies from a direct circle around the
earth. and Prof. Otto Klotz explains
the curious fact that the line, instead
of being straight, is at one point 500
feet south of the direct circle and at
another place 600 feet north. 1t was
decided that the astronomical parallel
or line through places where the
Pole is Al deg. from the zenith
should be the accepted boundary.
