"A French geologist has made n
careful calculation of the amount of
solid matter carried from the surface of
the land into the oceans of the earth,
and has reached the conclusion that at
the rate it is going it will take only
$4,000 years for all the land to slide
off into the water
by new process a superior guam
tity of illuminating gas is made from
wood (maple preferred) and crude oil
1t is called the Ramsdcll process, and
the inventor is said to have expended
$40, 900 in perfecting it. Charcoal is the
residue from the wood after extracting
the gas.

I'm relation to the influence of in
sects in producing color in flowers, a
writer in the Botanical Gazette contends
that there could not be distinct things
In nature without color-that color is
just as important in producing variety
in nature as form; and therefore there
would of necessity be as much color in
flowers as now, though never an insect
had appeared on the scene.

Nice, method of detecting the admiX-
ture of other oils with the genuine olive
oil from Nice has been discovered. The
process consists in the mixture of nj
trate of silver and alcohol with the oil,
which is subsequently boiled and
changes color, becoming reddish or
brown, instead of retaining the green
ish-gold of the pure olive-oil. The in
ventor of this process has also applied
it with success to the detection of mar
garine in butter, and much attention is
being directed to it in the Nice district.
Why trees or other plants grow
erect, has never yet been definitely de-
termined. 1t has been supposed to have
some relation to the action of light
Certainly plant usually growing erect
turns toward any opening for light in q
dark cellar; but when there is no light
they grow erect. DR. Maxwell S. Mas
ters has recently called attention tc
some cases in an English coal mine
1000 feet deep. Some props made from
green posts pushed out into growth
and, though in absolute darkness, they
were perfectly erect, and perfectly
blanched.-N. Y. Independent.
DR.. l.. Webster Fox is of opinion
that savage races possess the percep
ton of color to greater degree than dc
civilized races. In lecture lately de
livered before the Franklin institute
Philadelphia, he stated that he had jus
concluded an examination of $50 In
dian children, of whom 100 were boys
Had he selected 100 white boys from
various parts of the United States, h
, would have found at least five of then
color blind; among the Indian boys h
/ did not discover a single case of color
blindness. Some years ago he exam
I ined $50 Indian boys and found tw
@ color-blind, very low percentage whe
. compared with the whites Among tn
I Indian girls he did not find any.
