ever, perhaps all this may be reconcilable
to reason; far be it from me to presume
attacking so glorious a system as that of
attraction. The law that the heavenly
bodies are said to observe, in describing
equal areas in equal times, is supposed to
be demonstrated, and by this it would ap-
pear, that the centripetal and centrifugal
forces alternately get the mastery of one
another.
However, I cannot help thinking it
somewhat hard to conceive, that gravity
should always get the better of the centri-
fugal force, at the very time that its action
is the smallest, when the comet is at its
greatest distance from the sun j and that
the centrifugal force should get the better
of gravity, at the very time that its action
is the greatest, when the comet is at its
nearest point to the sun.
To a common observer it would rather
appear, that the sun, like an electric
body*
