SCIENTIFIC GLEANINGs.

Professor Ramsay thinks that color
blindness is defect of the brain instead
of the eye.
According to naturalists wasps remem-
Der the locality of their nests just nine
ty- six hours.
A mercury plumbbob has just been
made. It consists of small steel rod,
bored out and filled with mercury to give
weight.
A very useful polishing powder for
metals and glass is made OF finely ground
glass mixed with small proportion o.
dried soda ash.
1t has been discovered that wool satu-
rated with 10 per cent. of solution Of
glycerine can bear prolonged heat of
275 degrees without injury.
A French remedy for burns is 30 allow
the contents of syphon OF settler water
to flow slowly over the effected parts. It
quiets the pain speedily and expedites the

Anative OF Japan has Invented pro-
cess by which seaweed can be converted
into an almost untearable paper, which is
transparent enough to admit OF its being
used as window panes. In color it re-
sembles old window glass.
Sheet-steel is Row copper plated on
both sides by electro deposition and used
as sheet copper. The sheet is decarbon-
lied steel, and one of the copper sides is
timed. The new material is manufactur-
ed at Pittsburg, Pa.
Glass blowing is an art nearly 1000
years old, perhaps older; yet there has
never been any device discovered to take
the place of the human lungs in the blow
ing. Bottles, however, are blown with a
mold and mechanical bellows.
Sometimes the pressure Of an artesian
flow of water results from gas pressure
instead of from high head Of water.
Dakota, for instance, has several artesian
wells, 1000 feet deep, with $50 to 28O
pounds pressure, but there are no high
places near by to give this head of wat er.
Analysis of natural gas shows the pro-
portion of each constituent in 100 parts
of the gas TO be as follows: Cerbolic
acid and carbonic oxide, 6-1O each; oxy-
gen, $40; defiant gas, i; ethalic bydride,
5; marsh gas, 81; hydrogen, %; nitro
gen, 3.
Bulk-windows that are cased up from
the main store, may be kept free from
steam and frost by small door or pane
Oh grass bHdE Will swing open near bQ0 10 u
Of the window, so as to let hot air near
the top escape, and the cold air from
oat doors will go in and keep the glass
clean.
4 can of naphtha or benzine, arranged
with q closely fitted cover, is conven-

Electric light people are indignant over
| the assertion of Professor Weisner of
Vienna that the light discolors papers,
and is, therefore, damaging to books.
They claim that Sunlight does the same

| An English chemist has shown that
/ the brittieress of the bone of the aged is
not due, as is generally supposed, to an
increase of the proportion of mineral
salts with advancing years. From q
section OF the femur of fifty subjects of
different ages no difference in the pro-
por ton of ash be determined.
