NJ. Andres contends that hail is pro-
dueed during ascending whirlwinds.
Experiments in England have shown
that gas and oil are about equally sood for
lighthouses, and that the electric light is
superior TO either in fine weather, but
probably not so good in fogs.
The combined attraction of the sun and
moon SO modifes the intensity of gravita-
ton on the earth, NJ Poincare finds, that
the clock is retarded half a second yearly
at the equator and advanced second at
the poles.
The dioscope does for the eye what the
telephone does for the ear. An objective
lens is fitted in some hall of entertainment.
and by an electric wire communication is
established with a small white glass plate
in a room at any distance. Excluding the
light from this room a complete reflection
is obtained of what is passing in the hall
After much experimenting, DR.. Richard
son has found a satisfactory means of caus-
ing painless death, and has introduced it
into the Home for Lost Dogs, in London
The animals to be killed are placed in L
chamber charged with mixture of car
bonic oxide and chloroform vapor, when
they TRANQUILITY fall asleep and wake no
more.
DR.. Mills method of determining the
total solid matter in different waters is
based on the fact that Il small glass bead,
with weight attached, will rise in saline
solution OF known strength, the more
slowly the greater the amount of solvent
pressure The rate of ascent is also de-
pendent on the nature of the soluble
matter.
Sir John Fayer considers it most re-
markable that Il poisonous snake cannot
poison one of its species, and only slightly
any venomous snake, although it kills
harmless snakes. \ vigorous cobra can
kill several dogs or from dozen to twenty
fowls before It's bite becomes impotent :;
and then the rapid resacretion of virus
soon makes it as dangerous as ever.
\ scientific Journal reports that COM
position of sand, cork and lime nodded
into blocks in now on trial in Germany
for building light partitions 1t is said to
have the advantage of excluding sounds
better than ordinary brick-work, while
being light and good non-conductor
But composition of hardwood sawdust
applied on lath like common plaster is
cheaper than the German method of COR
structing partitions, is much lighter ard
has other desirable qualities.
A report submitted by Milne Home to
the Royal Society, Edinburgh, states that
at a period geologically recent in TIE
earth's history an arctic climate prevailed
in part of northern Europe, and as an effect
of this there occurred local glaciers in
Scotland, leaving some Of their traces still
visible. Subsequently Scotland was en-
tirely submerged beneath the sea, and most
of the valleys were filled with sand, gravel
and mud. A northwesterly current pre-
vailed, carrying masses of floating ice with
powders, which were deposited on the
hills
At the London Health Exhibition the
electric light was successfully used to light
Il bakers oven. This is the first time it
has ever been applied to such purpose
\ great difficulty has always existed among
bakers to get light into their dark ovens
so that the progress of baking might be
observed. This application, under the di-
rection of ". d. Gooch, of placing two in
candescent lamps driven by a Victoria
Brush machine inside an oven, where the
temperature ranges from 1909 to 600 Fab
renheit, is therefore notable advance.
The oven in which this invention can be
seen is that of Perkins & Sons, and worked
by Harris q Co., of Angels Cake" fame.
The oven door contains a sheet of plate
glass, through which the whole of the oven
is distinctly visible The baker now never
need burn his bread or pastry.
