i. c, that kind produced by the friction of resinous substances,
while the positive electricity is merely the absence or negation
of electricity. It thus reverses all our common notions of elec-
trical science.
Dr. Faraday observed, that while admitting to the very fullest
extent the value of the observations and investigations of MM.
Pelletier and Quetelet, which he had brought before his audi-
ence, he nevertheless could not receive the hypothesis they had
framed thereon. These researches on the electricity of the air,
are not only interesting in a meteorological respect, but intensely
so in a physiological and pathological point of view. While
they account for storms in cloudless skies, and for the occur-
rence of severe storms during the winter, or in very cold lati-
tudes, as at Cape Horn, for instance, (the Cape of Storms,) they
tend to thrun- light upon the exacerbations of disease at different
hours of the day, as well as on the increase and decrease of
epidemic and other diseases in different months of the year.
Such remarkable changes in the electricity of the atmosphere
cannot go on without affecting the static electricity of the human
frame. According to the researches of Casper, of Berlin, the
greater number of deaths from disease take place at the early
hours in the morning, when the quantity of electricity in the
air is reaching its minimum. Is this merely a coincidence, or is
there some yet undiscovered connection between the cessation
of life and the electrical state of the medium in which the
human body is placed ?
Weather Observations.
The British Board of Trade has seen fit to publish, for the use
of seafaring men, general maxims of weather, because the color
of the sky at particular times affords, with the barometer, good
collateral weather prognosis. Not only does the " rosy sunset"
presage fair weather, and " a ruddy sunrise " bad weather, but
there are other tints which bespeak with equal clearness and
accuracy. A &/-ii>7</-yellow sky in the evening- indicates wind ;
a j9a/e-yellow, wet; a neutral gray color constitutes a favorable
