The recent scientific exploration of
the Lake Of Liberals by Mons Lortet
has resulted in the discovery of several
new forms of fish and new species OF
mollusks in this celebrated lake
Old wine, says Macagno. owes its
mellowness more to the increase OF gly-
cerine than to Q decrease Of tannin In
the liquid. The keeping of the wine,
he maintains, depends upon the proper
ton the alcohol bears TO the tannin.
DIR. Julius Schmidt has lately pub
lished that he finds from the obserya-
tons of the red spot on Jupiter. during
q period extending from 1879 to 1880.
that an interval of 9 hours. IS minutes,
34.4 seconds represents the rotation Of
that planet upon its own axis. But he
is not quite sure about the matter after
all. and like q wise and prudent man
wants c~onfirmatory evidence.
Herr f. Schone, in the Berichfe. does
not attach any scientific value whatever
TO the ordinary potassium iodine paper
tests as ozone measures. A small
amount OF ozone in most air produces,
he says, a greater degree of color on
potassium iodide papers than a larger
amount of ozone in dry air. The hu-

He even goes so far as to assert that the
actual presence Of ZION in the atmos-
phere Is at present an open question
The minute lines and burrows on per-

more useful attention than the observa-

There is reason to believe that the spiral
whorls on the thumb and finger points
are peculiar to individuals and races.

1t should be widely known, because
Of evident importance, that at the inter
national geological congress to be held
at Bologna, in 1881, q prize will be
awarded Of 5000 francs for the best in
ternational scale Of colors and conven-
tional signs for graphic representation
Of formation on geological maps and
sections. Many Of our geologists might
go in for the prize. not for its money
value, but for the sake of making a GER
tain department Of geology Ineligible
when presented to the eye. The Babel
of coloring In geology at present here
and In other countries is enough to
cause o dispersion Of those that come
to learn, and depart in disgust when
they find that q very important means
Of conveying knowledge Is in itself con-
flictatory.
All the work in recent chemical re-
search, says Mr.. Pattison Muir, in O
paper just published, points unmistaka-
bly, toward the conclusion that chemis-
try is rapidly passing out Of the natural
history stage Of progress into that stage
where her facts will be accurately
grouped under general laws, which
laws will admit Of cumulative state
ment and of quantitative deductions
being made from them. The recent
work in chemistry also illustrates the
need Of . wide training in the methods
Of various sciences for the investigation
Of this branch Of natural phenomena
One man begins with a purely chemical
investigation, another with what APP
pears wholly physical; before long they
lind their paths meet, and that the prob
lem which each had attacked without
thought Of tho other cam. 1t Is seen, br
solved, and ever then solved but par
Tally. only by the efforts Of both.
