Since the period that
streams of meteoric shooting stars were first considered with reference to
the direction of their orbit as a closed ring, the epochs of these
mysterious celestial phenomena have been observed to present a remarkable
connection with the regular recurrence of swarms of shooting stars Adolph
Erman has evinced great acuteness of mind in his accurate investigation of
the facts hitherto observed on this subject, and his researches have enabled
him to discover the connection of the sun's conjunction with the August
asteroids on the 7th of February, and with the November asteroids on the
12th of May, the latter period corresponding with the days of
St. Mamert (May 11th), St. Pancras (May 12th), and St. Servatius (May 13th),
which according to popular belief, were accounted "cold days."*

November stream reappearing in the beginning of May ('Comptes Rendus', 1836,
t. ii., p. 670). M??dler has examined the mean depression of temperature on
the three ill-named days of May by Berlin observations for eighty-six years
('Verhandl. des Vereins zur Bedf??rd, des Gartenbaues', 1834, s.
