growth is yet to be discovered.
A hitherto unknown treatise on cleo
tricity, by Galvsni, has been discovered.
1t has been suggested to make sugar
bowls out of refuse bagaSse from the
Louisiana sugar factories.
Lunar rainbows are not common, but
have been known. In these cases the
moon takes the place of the sun.
The largest window glass tank in the
world was last week put in operation at
Jeanette, near Pittsburg 1t has ca
pacity of GO tons of melted glass.
The water power of the Rhine is about
to be utilized TO work electric dynamos,
which will distribute electric power and
light over radius of fifteen miles.
The gills of mackerel undergo fer
mentation, and no part Of the head or
near the head should be eaten after forty
eight hours of the fish being caught.
Tin and glass have found rival in
paper as a material for making kerosene
oil cans. The latter, it IS claimed, will
not rust and leak like tin, or crack like
glass.
"Linotypes" are Photographic prints
mounted on linen. Washes of color ara
applied to the back of the prints, so that
they can be used as colored transparcncics
with excellent effect
Paper pulp is now made from forest
leaves. If it prove equal to wood fibre
1t will be great saving of timber, for
the pulpers have been running a close race
with the lumbermen in decreasing the
honest face of this good earth.
There is not single article of clothing
on the human body where alcohol is not
used. Shoes, trousers, stockings, hats,

The ''fur' on the inside of the tea
kettle comes from the salts of lime in the
water. They are held in solution by the
carbOnic acid gas present, but when this
is driven off by boiling, they are precipi-
tated on the sides of kettle Scale in
steam boilers is due to the same cause.
Observations upon the sway of tall
chimneys during high winds show that
one Us in height, and four feet in total
diameter at the top waved twenty inches
during heavy gale, and another 164
feet high, but with a six and half feet
diameter of flue, moved through an arc
Of only six and half inches.
The efficacy of filters has been ques-
toned and denied in many professional
quarters. A New York doctor has re-
Gently called attention to the fact that,
so far from lessening the number Of BAG
terra, tiltering substance may allow a
more rapid multiplication Of micro organ
isms than untitered water would ordina-
rily undergo, and that even in the best of
filters the germs of disease may be bred.
1t seems that the highest point at which
regular meteorological observations arc
made is on the Andes, in Peru, at
height of IA, 300 feet. Harvard College
has a weather observatory in Colorado
only few feet less than the former. The
station on Pixies Peak is at an altitude Of
IA, 100 feet. In Europe there are but two
stations at any considerable height, these
being about 10, 900 and II 900 feet re-
Spectively.
Experiments again made in London
with carbO-dynamitc, one Of the latest
explosives, would seem to show that it
possesses some important advantages over
ordinary dynamite, among others that Of
considerably greater power, and the gen
Grafton of much less noxious vapor when
exploded in confined places. 1t is com
posed of nitro-glycerine absorbed by ter
parts of a variety Of carbon, and is
claimed to be entirely unaffected by
water.
Several cases Of cancer have been sue
cessfully treated by DR.. J. Inglis Parsons,
by passing a powerful interrupted voltaic
current through the tumors. The growth
as whole does not entirely disappear,
but remains as an inert mass, probably
composed Of fibrous tissue. This, the
doctor thinks, could not be absorbed,
but the remains Of the growth could al
ways be removed by the knife, suisse
quently if desired.
