invisible seeds are scattered by the
wind, and In favorable weather the
growth attacks and destroys vast
swarms of the insects Since its dlscov-

mould has been regularly distributed
by the department Of agriculture. The
disease thus artlfloially spread has been
very effective but dryness has caused
some failures
Mosquitoes are known TO live through
the winter. awakening with the first
warmth. A late investigation by Mr..
John b. Smith proves that certain
species hibernate In the adult state,
others In the larval state also, others
only in the laryal state, and some In the
egg. Many larvae survive repeated
freezing and thawlng.

quite astonishing is the rapldlty Of
working Of brain and nerves IN modern
pianO-playlng Al the conference of
musicians IN Dublin, II was shown that
the ordinary player must cultivate the
eye TO see about 800 signs per minute,
the fingers TO make about 1000 move
ments, and the brain to perceive the
800 signs while issuing 1000 orders,
In a part OF Choplns "Etude in T.
Minor" the rate of reading must reach
$3.50 signs in 2ls minutes. This Is
equivalent TO about % notes per second,
and, as the eye can receive only about
10 consecutive impressions per second,
The notes must be read In groups III
stead OF sIngy.
In his experiments in electric anaes-
thesia, NJ Leduo has used maximum
current Of 50 volts, and This was passed
through electrodes Of cotton moistened
with saline solution, one of which was
applied over the kidneys and the other
upon the forehead. The current was
increased TO the maximum In five min
utes. A numhness of the limbs was
followed by loss Of speech. and then by
a suspension Of the other faculties, The
only disagreeable sensation was night
mare. The breathing was somewhat
INSTRUCTED, but the heart was not az
fected, and consciousness, with sense
of inVlgOration. came instantly on
breaking the current. There seems TO
be risk in stoppage of breathing by
too long application.
Ordinary thermometers are known 10
be very inaccurate, varying many de-
grees, and this fact throws doubt on
many reports Of extreme summer or
winter temperatures. Even the scien-

grades prove to be unreliable, although
their indications have been placed on
record as results OF great precision
Medical men especially have need OF
tested instruments, and the late start
