DURING the past season two natural.
lists, G. W. and E. g. Peckham. have
found that wasps remember the locality
OF their nests for ninety-six hours.
PROF. w. RAMSAY suggests that color
blindness is probably defect in the
brain instead of the eye. It is anal
ogous to the dullness which prevents .
person from distinguishing an octave's
difference between two musical notes,
though both netes are heard, there being
no deafness.
DURING the past two seasons e. B.
Poulton has made observations which
prove that the silk of at least three
species of English moths is greatly af-
fected in color by environment at the
time of spinning. The cocoons were
dark brown when the larvm had been
placed in bag of green leaves, and
white when they had been freely ex-
posed to light in the neighborhood of
white surfaces.
The average watch is composed Of
It's different pieces, comprising up
wards of 2,4OO separate and distinct
operations in its manufacture. The
balance has $4,000 beats or vibrations
per hour, 12,96O,OSO in thirty days,
Isl, $4,000 in one year; it travels
LAB inches with each vibration,
which is equal to 81 miles in twenty
foul hours, 1921 miles in thirty days.
or 3,55Sf miles in one year.
DIR. G. A. WHITE thinks he has solved
the mystery of what becomes of all the
antlers that deer shed every year. Al
though the antIers when the deer is
killed before they are removed will
withstand all weathers for years, it is
very rarely that pair that have been
shed are found. Dr.. White asserts that
he has discovered small insect that
attacks the antlers, and within short
time after they are shed destroys them
by burrowing through and through
them.
DIR. BRowN-SEoUARD, who has been
preaching that bad ventilation and poor
and monotonous food are great causes
of phthisis, has exhibited to the Paris
Academy of Sciences ventilating ap-
paratus of his invention. A reversed
funnel, the shape of lamp-shade, is
placed at the end of a tube, SO arranged
in its curves and angles that when
placed beside bed the reversed funnel
will be above the sleeper and draw up
the air he breathes. The other end
runs into the chimney of the room. If
there be none it is taken through
heating apparatus to an air-hole. The
heat is great enough to burn the disease
germs.
SOME curious experiments have led
DR.. Urbanschitsch, of Vienna, to the
conclusion that the exciting of one
sense organ increases the acuteness of
The others, the different sensations
to REINFORCE one another.
Hearing sound will bring out the just
ndistinguishable color of distant
disk. The ticking of a watch is heard
more plainly with open than closed
eyes, the fact that we listen to music
Dr. speaking with the eyes closed being
lue to other reasons The sight of red
and green increases perceptions of
sound; that of green and red weakens
hem. These colors affect sensations
IF smell, taste, and touch in like man.
Ter. Touch and temperature act re-
,iprocally. When the skin is tickled
md plunged into warm water, the tick
ing ceases; when into cold, the tick
ing brings out the feeling OF cold.
These observations offer an explana-
ion of the singular associations be-
ween colors and sounds that some in
lividuals retain.
