lists, consists OF some such mixture as
fifteen grains OF anhydrous sulphate OF
sodu, nine grains OF caustic soda and
twenty grains OF anhydrous hypo.
which are ground and used with nine
grains OF kachin. The whole is made
INTO strong solution with sugar or
dcxtrine. and the, sensitive plate is coat.

paper or soluble geIatine being then at
tached to protect the chemical coating.
On placing the plate in water, z the
chemicals quickly dissolve, when tho
covering can be removed and thrown
away. development aud fixing being ef-
fected by the solution. Photographic
printing paper is similarly prepared, a
coating Of waterproof yarnish being
applied to the back before the develop!

as the ideal home. both of malaria and
of the species OF mosquitoes supposed 10

periments and among the few fever
stricken people inhabitlng the district.
Just before sunset they seal themselves
up in their hut until sunrise, and hope'
thus to avoid mosquito bites and pass
the season in health.

feet in size was built OF the bricks, lad
in hydraulic mortar, the exposed side
being coated With n thin layer of nv.

an hour. The temperature rose to 1850
degrees Fahrenheit. yet the material
was unaffected. and the surface Of ths
partition opposite the fire remained SC
cool that matches held against Itwould
not ignite. even when the Temperature
was highest.

The aurora australIs, as seen by Arc
towskt on the recent trip, of the Bel
gica. was striNlngly similar to the
aurora boraalls as witnessed by, Nord-
cnskjold about twenty years ago. The
phenomenon was observed sfxty-two
times. generally between : p. m. and |
A. m. with q maximum Intensity be-
tween Q and 10 p. m. Its. greatest lre-
quency was not during the months OF
polar night, and the most brilliant dis
plays were near the equInoxcs.

An electric railway, with

being raised nine md onr-halt feet
above the towing-path, is being tested

boats can be made heavier than those
drawn by horses.
