SCIENTIFIC MISCELLANY.

The THEORY OF VAocINATIoN. PROF.
Tyndall suggests, that, just as the soil may
be so efectually robbed Of some essential
ingredient by one abundant crop as to be
incapable of producing another, so in the
human system parasitic disease may so
completely exhaust the blood Of some In
gredient necessary 10 the growth and prop.
agation OF the parasite that the production
Of second crop in fatal or considerable
quantities may be impossible. 1t would
thus appear that protective vaccination or
incubation is simply the introduction into
the blood OF weakened and comparatively
harmless disease germs TO consume the
m aterial which might become food ter
similar germs in more vigorous and dan
gerous condition.
WIND WoRK.-A gale at East St. Louis
in 1871, according 10 Mr.. G. Shaler Smith,
overturned locomotive, exerting force
of no less than 90 pounds per square foot.
AT ST.. Charles jail was destroyed in 1877,
the pressure required being 81 pounds per
square foot. At Marshfield, in 1880, a
brick mansion was leveled, the force neces-
sary being SO pounds per square foot.
Below these extraordinary pressures, Mr..
Smith has instanced numerous cases Of
trains being blown off rails, and bridges,
etc, blown down, by gales OF "a to 81
pounds per square foot.
Successful experiments in distributing
the electric light 10 great distances have
been made In connection with the Turin
Electric Exhibition. A Siemens machine
Of thirty horsepower generated current
which was simultaneously used by several
electric light systems spread over circuit

Amotor driven by small charges Of gun
cotton is an English novelty. II is said 10
be applicable wherever small powers are
required.
AGerman botanist has given instances Of
the modification Of plants by insects so as
to produce new varieties.
GRKAT WoRMs.-According TO Mr.. +. Z.
Beddard, London zoologist earth worms
two feet In length have been found in the
British Isles, and various species as large
or larger are known to exist In South
, America, Western Africa, Australia and
!. New Zealand The largest species known
however inhabits South Africa. Forty
years ago specimen'was described which
, measured six feet two inches in length
: but II seems to have been nearly forgotten
until the other day, when gigantic Great
ure Of the same species was sent to III,
. London Geological Gardens from Cap,
J. Colony. The longest measurement o
this worm yet taken reaches six feet five
inches, the diameter being nearly half al
inch.
