Receiver, did plainly prevent its own
Deſigne, by ſo impelling the Value, as

And this minds me to take notice of
another deficiency, pointed at by our Ex

thoſe Pleniſts we reaſon with; for many
of thoſe unuſual motions in Bodies, that
are ſayd to be made to eſcape a Vacuum,
ſeem rather made to fill it. For why,
