but a little French, you were to converse every day a little among some
Frenchmen in your neighbourhood, and suppose those Frenchmen, you thus
kept company with, were every one of them fools, mere ignorant, empty,

I knew a philosopher that was excellently skilled in the noble science
or study of astronomy, who told me he had some years studied for some
simile, or proper allusion, to explain to his scholars the phenomena of
the sun's motion round its own axis, and could never happen upon one to

was the broad-headed nail in the centre, which was as the body of the
