The 31 Experiment, concerning the Phæ
nomena of two flat Marbles exactly plain'd
and wrought together, and the true reaſon
thereof, 229. The Authors intention for the
further proſecution thereof, & what hindred
him; the reaſon why the under Marble did
not fal from the upper (being onely conjoynd
with Spirit of Wine) when the Receiver was
evacuated. And a notable relation concern
ing the coheſion of flat Bodies. 231 &c.
