The view of the original existence of
p 123
small planetary masses in space is simpler, and at the same time, more
analogous with those entertained concerning the formation of other portions
of the solar system.
It is very probable that a large number of these cosmical bodies traverse
space undestroyed by the vicinity of our atmosphere, and revolve round the
Sun without experiencing any alteration but a slight increase in the
eccentricity of their orbits, occasioned by the attraction of the Earth's
mass. We may, consequently, suppose the possibility of these bodied
remaining invisible to us during many years and frequent revolutions. The
supposed phenomenon of ascending shooting stars and fire-balls, which
Chladni has unsuccessfully endeavored to explain on the hypothesis of the
'reflection' of strongly compressed air, appears at first sight as the
consequence of some unknown tngential force propelling bodies from the
earth; but Bessel has shown by theoretical deductions, confirmed by Feldt's
carefully-conducted calculations, that, owing to the absence of any proofs
of the simultaneous occurrence of the observed disappearances, the
assumptiopn of an ascent of shooting stars was rendered wholly improbable,
and inadmissible as a result of observation.
