The amount Of water passing over Mag.

A French manufacturing firm has

that Is said TO combine the qualities OF
linen and silk, with double the strength
Of linen.

The lightness of snowfakes is the re-

times as many volumes of air, entangled,
so to speak, among their crystals, as they
contain water. Very fine and lightly

four times as much space as water, and is
from ten to twelve times lighter than an
equal bulk of that fluid.
1t is now claimed that in the copstruc-
ton OF boiler furnaces an advantage is
gained by forming the CRATE out of a
perforated plate, instead of the series of
bars. The perforations are placed in
lines, and in vertical section are broader
at their lower end than at the upper sur.
face OF the plate; the latter may be made
OF cast or wrought iron, steel, ETC., all
In one piece, or of number of sections
placed side by side, and the tapered
holes may either be circular, square, or
Of any other convenient form.
The slow tapping of butterfy's wing
produces no sound, but when the move
ments are rapid noise is produced,
which increases in shrillness with the
number of vibrations. Thus the housetly,
which produces the sound F, vibrates its
wings 20, 100 times a minute, or 3S5
times second; and the bees, which
makes sound of A, as many as 26, 400
times, or 400 times in second. On the
contrary, tired bee huns on f, and
therefore, according to theory, vibrates
its wings only $50 times in a second.

During the Stone age bodies were al

body was usually laid a weapon, tool Or
'eme ornaments. We often find In graves

slowed upon the last resting place of the
departed certainly betokens belief in
The future life; but the things placed by

hat life was believed to be merely con-
mutation of the life on earth, with the
'ame needs and the same pleasures.
