S., and might consequently be
identical with the stream of St. Lawrence's day, taking into account that it
has advanced since the epochs* indicated.

If the fall of shooting stars of the 21st of October, 1366, O.S. (a notice
of which was found by the younger Von Boguslawski, in Benessius de Horowic's
'Chronicon Ecclesi?? Pragensis'), be identical with our November phenomenon,
although the occurrence in the fourteenth century was seen in broad
daylight, we find by the precession in 477 years that this system of
meteors, or, rather, its common center of gravity, must describe
p 129
a retrograde orbit round the Sun. It also follows, from the views thus
developed, that the non-appearance, during certain years, in any portion of
the Earth, of the two streams hitherto observed in November and about the
time of St. Lawrence's day, must be ascribed either to an interruption in
the meteoric ring, that is to say, to intervals occurring between the
asteroid groups, or, according to Poisson to the action of the larger
planets* on the form and position of this annulus.
