The new method of producing gen
eral anesthesia proposed by Schneider
lin of Berlin, consists in giving three
hypodermic injections-two hours. one
hour and half an hour before opera
tion-of scopolamine with some NOR
phine. Inconsistencies continues
some hours after the opsiation.
The British birth rate has been
steadily declining in recent years. and
the latest report shows the lowest rate
on record-twenty-sev per one thou
sand for London and 292 per one
thousand for seventy-five large towns.
This scarcely exceeds the death rate,
which must become the greater within
a Few years. Sanitation has reduced
the death rate, particularly among in
fants; this alone has postponed the be-
ginning Of race decline beyond the
present time. The falling off in the
birth rate-due partly to selhshness,
and love of pleasure and partly to our
strenuous modern living-is most seri-
GUS among the middle and upper
| classes.

The storage of heat from the sun,
first pointed out by Kalescinsky in
1901 In some small salt lakes of Hun
gary, has now been observed in salt
lakes of various parts Of Europe and
in Siberia. In the Szovata lakes. a
warm layer several yards thick. was
found between two cooler layers. and
condition of the heating is the exist
ence of a layer of fresh or diluted salt
water over the notwithstanding layer
Even fresh water will be heated I'M
der a covering of oil. The stored heat
sometimes rises to 100 degrees F., and
may be retained for a considerable
time, and in a lake of Norway It
proved destructive to oysters until the
cold water was let in from the open
sea. Artificial solutions of various
salts may be made to serve like the
salt lakes as heat accumulators.
Now that the Isthmus of Panama is
about to be pierced with a canal,
which will form a waterway for ma
rine life as well as for ships between
the two oceans, the need OF biological
survey Of the fresh waters Of this 18TH
mus is suggested as a proper subject
for the attention of Congress. One
problem for which a solution is sought
is that Of the connection between the
fresh-water fauna Of the Atlantic and
the Pacific slopes of the isthmus.
There are indications that the fishes
Of the Pacific slope streams crossed
the divide from the Atlantic slope in
times much more recent than that of
the interoceanic connection which, it
is believed, once existed at Panama.
The completion of the canal before the
making of the proposed biological sur
vey would obscure the problem by
producing an artificial mingling of the
faunas of the two slopes.
