Humboldt, Alexander von, 1769-1859

"COSMOS: A Sketch of the Physical Description of the Universe, Vol. 1"

(Brandes,
'Unterhalt. f??r Freunde der Physik', 1825, heft i., s. 65, and 'Comptes
Rendus', t. v., p. 211.) Capocci, in the interval between 1809 and 1839, a
space of thirty years, has discovered twelve authenticated cases of
a?‘rolites occurring between the 27th and 29th of November, besides others
on the 13th of November, the 10th of August, and the 17th of July.
('Comptes Rendus', t. xi., p. 357.) It is singular that in the portion of
the Earth's path corresponding with the months of January and February, and
probably also with March, no 'periodic' streams of falling stars of
a?‘rolites have as yet been noticed; although when in the South Sea in the
year 1803, I observed on the 15th of March a remarkably large number of
falling stars, and they were seen to fall as in a swarm in the city of
Quito, shortly before the terrible earthquake of Riobamba on the 4th of
February, 1797. From the phenomena hitherto observed, the following epochs
seem especially worthy of remark:
22d to the 25th of April.
17th of July (17th to the 26th of July?). (Quet., 'Corr.', 1837, p. 435.)
10th of August.
12th to the 14th of November.
27th to the 29th of November.
6th to the 12th of December.
When we consider that the regions of space must be occupied by myriads of
comets, we are led by analogy, notwithstanding the differences existing
between isolated comets and rings filled with asteroids, to regard the
frequency of these meteoric streams with less astonishment than the first
consideration of the phenomenon would be likely to excite.
