The exact function Of potash in plant
growth is yet to be discovered.
A hitherto unknown treatise on cleo
tricity, by Galvani, has been discovered.
II 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. II has a 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 u radius of fifteen miles.
The gills of mackerel undergo fer
mentatipn, 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 are
applied to the back of the prints, so that
they can be used as colored transparencies
with excellent effect.
Paper pulp is now made from forest
leaves. If it prove equal to wood fibre
it will be great saving of timber, for
the pulpers have been running a close race
with the lumbermen in deforesting the

There is not a single article of clothing

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

one 115 in height, and four feet In total
| diameter at the top waved twenty inches
during a heavy gale, and another 164
feet high, but with 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,
80 far from lessening the number of bac-
teria, a tiltering substance may allow a
more rapid multiplication of micro organ
sms than unfiltered 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 are
made is on the Andes, in Peru, at a
height of IA, 800 feet. Harvard College
has a weather observatory in Colorado
only a few feet less than the former. The
station on Pixies Peak is at an altitude OF
Ii, 100 feet. In Europe there are but two
stations at any considerable height these
being about 10, 900 and 1900 feet re
'pectively.
r Experiments again made in London
with carbo-dynamite, one of the latest
explosives, would seem 20 show that il
possesses some important advantages owe
ordinary dynamite, among Others that o.
considerably greater power, and the gen
'ration of much less noXious vapor wher
exploded in confined places. 1t is com
posed of nitro-glycerine absorbed by ter
parts of variety of carbon, and i
claimed to be entirely unaffected b!
water.
Several cases of cancer have been sue
.essfully treated by DR.. J. Inglis Parsons
by passing a powerful interrupted voltai
current through the tumors. The growtl
as a whole does not entirely disappear
but remains as an inert mass, probabl,
composed of fibrous tissue. This, tn
doctor thinks, could not be absorbed
but the remains of the growth could al
ways be removed by the knife, subse
quently if desired.
