There is another form of aurora frequently observed in northern
countries, and that is the one that is seen to occur above clouds, and
that has the appearance of a wide piece of drapery with undulating
folds. As it is the form most usually represented, we shall not dwell
upon it. On the contrary, we shall speak of other phenomena of the same
origin, and much less known, that Mr. Lemstrom describes. It concerns
those auroral lights that shine at the edges of clouds, or that form
around the tops of the mountains in Spitzbergen or in the Alpine
districts of Lapland. According to the Finnish observer, it would be
impossible to tell by the naked eye whence this light comes, but, by
means of a spectroscope, we find that it is of the same nature as the
aurora. Sometimes, these strange lights take on the form of flames of
but little brightness, which, at short intervals, rise from the crest
of the mountain and suddenly vanish (Fig. 4).
These phenomena sometimes exhibit themselves at the level of the
earth's surface, or upon the roofs of houses.
Finally, Mr. Lemstrom describes the diffuse light which sometimes fills
the atmosphere of the polar regions, thus proving that the phenomenon
shows itself from time to time in the vicinity of the earth itself.
Meteors of the same nature as the light of the auroræ boreales do not
occur solely in the polar regions, and the author demonstrates, not
without attaching much importance to it from the standpoint of the
theories to which he has been led, that they are observed in other
countries of the earth. In Peru, Bolivia, and Chili the summits of the
mountains are often seen illuminated by a brilliant light. This light,
which occurs especially in summer, has been compared to heat lightning
by scientists.
Similar observations have been made in the Swiss Alps. Dr. De Saussure
has seen electricity escape through all the projecting parts of
objects, and the same phenomena have been observed upon the high
plateaus of Mexico. Again, we may cite the fact that Brewster observed
a light upon a church tower during an aurora borealis. In every country
phenomena similar to polarized light may occur.--_La Nature_.

IN 1886, 17 Gloucester fishing vessels were lost, worth
$115,800, and 115 fishermen never came home. The year was remarkable
for the small inshore catch, almost all the fishing being done on the
high seas.
