described by CAPT. SEYMOUR of Cork. "For nearly an hour we could not see
each other nor anything else, but merely the light, and most
astonishing, every one of our finger-nails turned quite black and
remained so nearly five weeks afterwards. This fact may be classed among
other proofs of the agency of electricity in the production of
hurricanes."

The following facts are entirely inconsistent with usual methods of
explanation of the cause of winds: "The entire atmosphere, to the
altitude of many thousand feet, is constantly traversed by numerous
horizontal currents of air, flowing in different directions and at
different heights."

The course of a balloonist was altered no less than five times in the
space of fourteen hours. "The aeronaut GREEN, at the height of 14,000
feet, encountered a current that bore him along at the rate of five
miles per hour, but upon descending to the altitude of 12,000 feet he
met a contrary wind blowing with a velocity of eighty miles an hour."

The vito-magnetic fluid is capable of becoming amassed, condensed and
rarefied. In the tornado that happened at Natchez, in 1840, the houses
_exploded_ whenever the doors and windows were shut, the roofs shooting
up into the air, and the walls even of the strongest buildings bursting
outward with great force.

On the 18th of June, 1839, a whirlwind fell upon the village of
Chatenay, near Paris. In the room of a house over which it passed,
several articles of needle-work were lying upon a table. The next day
some of them were found in a field at a distance from the house,
together with a pillow-case taken from another room. They must have been
carried up the chimney by the rush of air outwards, as every other means
of exit was closed.

It is a fact well-known to miners that during and before violent
tempests, strong ascending currents are observed.

If a metallic rod terminating in a point be attached to the conductor of
an electrical machine, electricity escapes in large quantities from the
point. A continuous current is thus kept up and the flame of a taper, if
placed in front of the current, is blown in a horizontal direction. Wind
is thus _manufactured_ on a small scale. Pl. IV.

At a recent meeting of a Meteorological Society in England, a paper was
read by the REV. JOSEPH CROMPTON, M.A., F.M.S. "The author, when walking
close to the Cathedral of Norwich, was struck with the unusual
