The first industrial application Of
the principle of electrical osmose is
said to be the Nodon- Britoneau pro-
cess of seasoning timber, in which the
electric current is made to drive out
the sap and replace it by unchange-
able solid matter. The solution kept
by a steam pipe at 1907 Fair, is
made to nearly cover the wood, a
lead grating supporting thelog being
connected to the positive pole of a
dynamo, and lead plate, on q porous
cover of felt and canvas, to the mega
tive pole. The separation of the
electrodes by q porous, partition
causes the solution to increase about
the negative pole. In public trial
of the process the solution used con-
tanned 10 per cent. of borax, 5 per
cent. of resin and rs per cent. of car
Donate of soda, and the time neces-
sary to draw this up into a ten-lnch
log was seven or eight hours. After
treatment the wood is dried in open
air for several weeks or even months.

An attempt to keep the animals
brought in by the natives from the
bush is being made at Carnot, in the
Congo. Though some die and others
escape, an interesting collection has
been made, including monkeys, small
rodents, villa hogs, jackal, young
tiger cat, with dogs, horses, asses and
horned cattle. The last named are
rapidly multiplying. The animals
are allowed much liberty, some Of
them having become very tame, and
a large monkey has learned to take
care of the sheep.

A report by M. Perisse states that
four processes for disposing of the
waste of Paris have been suggested
direct employment for agriculture,
incarceration, steam treatment and

The discovery that mosquitoes are
for the spread of malaria
s giving rise to hopes of Danish
ng one of the most dreaded scourges
If the tropics. Major Ronald Ross
researches in India show that this
8 probably the only source of infec-
ion, and gives grounds for believing
hat not all kinds of mosquitoes are
dangerous. Thus far the "spotted
winged" mosquitoes seem to be the
,nly offenders, the malaria parasite
having been found .intwo species of
hese creatures in India and one in
tally. Their breeding places are
are in India, being only shallow
ouddles OF rain water that do not dry
lp under a week or more; while the
COMMON species find breeding places
lear every dwelling-tha ''brirdled
mosquitoes" in cisterns, bitches and
lraihs. The problem of dealing with
Malaria, therefore. is greatly simpli-
led if the present conclusions prove
o be correct. It is simply necessary
o drain or treat with chemicals the
comparatively few pools yielding
potted winged mosquitoes. and the
disease will disappear through the
Of it's carriers.

Lighting by a new low pressure
Icetylene system is expected by a
Paris street railway company to
prove more satisfactory than electric
ty. The material used is the "acety-
