According to Mr.. Beaudemoulin, if q
quantity of dry sand be placed in box OF
tia sicct-iron, or even In canvas bag, and
subject ted to q slight compression, it forms
a mass capable of resisting a pressure of
fully sixty tons, without breaking or even
straining the envelope. The sand, how
ever, remains perfectly divisible, so that if
"A small hole be made in the box or bag it
will flow slowly, and with so little force
that even a small piece of paper pasted
over the opening will check the flow even
with the sixty tons. weight upon it. NJ
BcaudemoulIn thinks this discovery may be
ut lizcd for building purposes, since the
fiil5d boxes need merely be held IN place by
II framework while being very thick, they
would form protection for dwellings
against variations of temperature. Such
walls, moreover, would be ire-proof. 1t
is also suggested that for lowering heavy
buildings, or even entire buildings, which,
by a change of street levels have been left
too high above the roadway, the sandbags
could be placed beneath, and their contents
allowed gradually to escape, thus letting
the load slowly settle down.
The French have recently devised
method of treating ordinary wood in such
a manner as to produce an almost undstin-
guishable imitation of mahogany. This
method consists in first planning the surface,
so as to render it perfectly smooth, and then
rubbing it with diluted nitrous acid; which
prepares it for the materials subsequently
to be applied. Afterward, one ounce and
half of the gum called dragons blood,
dissolved in pint of alcohol and one-third
of that quantity of carbonate of soda are
| miXed together and filtered. and the liquid
IN TINS state is then rubbed, or rather laid
upon the wood in careful manner with a
soft brush. This process is repeated with
but little alteration, and in very short in
terval atterward the wood assumes the ex
ternal appearance of mahogany to such a
degree that 1t has been extensively intro
duced as substitute for that now costly
material. SO perfect, indeed, has this art
become. that the surface thus prepared re-
fleets objects like mirror, and, in case the
polish becomes less brilliant on account of
exposure, little cold-drawn linseed oil,
rubbed upon the wood, will restore its lus.

advantages. People of delicate constitu-
tions are so liable to cold that to take a
bath Is to get cold. Children are unmer-
cifully and cruelty treated, often killed, by
forcing them into tub of water when they
were crying and struggling to resist it, by
doing which the perspiration became

Tue French photographers are not will
lug 10 abandon the idea of producing pho
torral BIS in natural colors. AT present
much attention is directed to the process
orr iLally proposed by Ducos de Hauron.
Three negatives are taken in the camera
the first through the red, the second through
orarge red, the third through violet glass.
From these three carbon prints are made
under the first negative he exposes film
nt hlchromatized gelatine having red tint,
under the second similar film of a blue
color. aud under the third a yellow film.
The three impressions terminated, he sup
. ises these three monochromes and obtains
nm image in which all the different tints of
the original are found. Unfortunately this
method involves numerous delicate trans
fels and a good deal of difficult manipula-
ton.
In memoiron cyclones and waterspouts,
Muuchoz publishes some observations made
by him while upon the ocean, and which,
if correct, are quite important. According
to him, at or near the surface of the ground
the movement of air in the cyclone is al
ways from below upward, while in whirl-
winds the movement is, on the contrary;
from above downward. In the former
case the winds are winds of aspiration in
the latter the wind descends from the cloud
in the form of bag or tube, which ter
inmates in point. He believes that wa
ierspouts have no relation whatever to
cyclones, having an opposite appearance
and cause. In this opinion Renou also
concurs.
A medical authority asserts that the Sc
verest catarrh cold can be removed in
about ten hours by mixture of carbolc
acid. ten drops, tincture of iodine and
chloroform, each rs drops. A few drops
of the mixture should be heated over a
spirit lamp in test tube, the mouth of
which should be applied to the nostrils as
| yolatlization is effected. The operation
should be repeated in about two minutes,
when, after the patient sneezes number
of times the troublesome symptoms rapid
| ly disappear.
Never paper wall over old paper and
paste. Always scrape down thoroughly.
Old paper can be got off by damping with
saleratus and water Then go over all the
cracks of the wall with plaster of Paris,
and finally put on wash of weak solu-
ton of carbolc acid. The best paste Is
made out of rye flour, with two ounces of
