Considering the phosphorescence OF
marine animals, Prof. Mcintosh
states that the light is produced by
four distinct methods, viz: a. By
special cells secreting phospherescent
mucus; ~ by special cells that are
phospsorescent without any visible
secretion; (3) by ordinary tissue
under nervous action; and a. by
bacteria. The entire absence of heat
is the most striking feature. Though
the light of the FREELY is cold, to pro-
duce it by the usual rocesses-except
the Geissler tube-would require a
temperature approaching 1000 degrees
and 1t is this remarkable economy of
energy in nature that leads to the
hope of greater efficiency in artificial
lighting.
Data respecting 48 wells or borings
more than 1000 feet deep are collected
by an American hydrologist. Of
these the TransvaaI has "a; United
States 10; Germany, 6; Queensland, g.;
New South Wales, l; South Australia,
l. The deepest are /: Paruschowitz,
Upper Silesia, Germany, 6,572.6 feet;
Schladebaoh, Germany, 5, 735; Springs
near johannesburg, Transvaal, 5,582;
West Elizabeth, Pa, 5,575; Doornk-
loof, Transvaal, $3.50; Aleppo Pa,
5, 800 feet.
The daily work of grown man has
been found by French psychologist
to be about 0.47 horse power hour.
He calculates that 25O workmen at 8
francs per day, or a total of 750
francs, would yield 100 horse power,
which would be supplied by horses at
a cost of 80 francs and by gas motor
for 3. 80 francs.
A close relation between rainfall
and tree-growth has been shown by
Prof. E. E. Bogue, of Lansing Mich.
A fall of 30 to 35 inches gave width
of ring of oil to 0.15 inches, and an
abnormally large or small rainfall
affected the tree growth of the follow
ing year.
Life is not only what we make it,
but its length depends very largely
upon ourselves. French psychoIo-
gist, Jean Flnot, urges that a most
important means of prolonging it is
auto-suggestion, or will power. He
states that the possible life span can
be shown theoretically to reach $50
or even 200 years, and that practically
it is much greater than is usually i'm
agined. Old age comes prematurely
through abuse of o-suggestion by
loss OF confidence in our strength
and powers. 1t Is pre- eminently es-
sential that we keep cheerful and
hopeful, banishing depressing thoughts
of the shortness of time and of human
frailties, that we remain active, and
that we make rational use of the
functional organs. Statistics show
that the critical period of old age is
actually between 80 and S5 after which
probabilities favor reaching OF exceed
ing the century mark.
New evidence in evolution making
necessary, certain changes IN zoologi-
cal class1fication-has been found in
the eyes of animals by DIR. Lindsay
johnson, the British ophthalmog1st.
A most remarkable result is con
firmation of Darwin's theory by the
fact that the eyes of man and of all
apes are practically Identical, each
having the highly complex system of
veins and arteries and the direct or
parallel vision. In going down the
animal scale, the eye gets further and
further from parallel vision. The
dog is found to have two ancestors in
the round-eyed hyena and the oval
eyed bear, though the racooon, the
hare and other animals exposed to
pursuit can see all around and all the
rodentia squint. The ophthalmoscope
proves the horse to be related to the
camel and other tropical animals, its
puzzling eye-pigment being the same,
with the evident function of protect
ing from sunlight.
In the 33 years ending with 1900
England lost from the wearing away
of its coasts Al, 378 acres, estimated
in the report of the surveys to have a
value of So, ,OOO, 900. AS the gain from
new land deposited has been deduct
ed, the total denudation was con-
s1derably greater.
What may be called powder of
hydrogen peroxide, or oxygenated
water, is an interesting discovery
claimed by M. Joubert, a French
medical man. The substance is per-
borate of soda, and when placed IN
water it yields solution having all
of the properties of free and chem
ically pure oXygenated water and all
of those of borate of soda. 1t can be
preserved indefinitely in the form OF
powder. The solution is affirmed to
fill the place of the non-poisonous
and oderless oxygenated water as an
antiseptic, and to be free from the
occasional irritating acidity of that
much used antiseptic, 1t also serves
