Another argument to demonftratc the Exiftence of In- 
corporeal Beings he deduceth from the Succcflive Durati- 
on of the World. And then pafleth on to prove the fame 
(which doubtlefs the Reader will be furprifed at) from di- 
vers phenomena of Nature, by him conceived not expli. 
cable by meer Mechanical caules ; as from tho(e of Gravi«

Boyliarja^ as that of the Suckers afcent with a great weight

concerning the Gravitation of water upon water j and 
concerning ponderous Bodies not finking at a com- 
petent depth 5 and the Body of a Diver not fenfible of

of the Sea i fromMagnetifmes, from the Bignefs and Fi- 
gure of the Sun and Stars 5 from the immenfe Celerity of 
the Globuls in the upper part of the Vortex, and the Mo-

together with its Explication^ where he undertaketh both 
to make it out. Why an extended spirit \% more capable of 
Perception, than extended Matter ? jipd^ to fliew. How a 
Spirit, lb (ubtile and penetrative, that it feems not capable 
of adhering to Matter, may yet be conceived able to move 
and impell Matter ? And that the cohasfion of a Spirit with 
Matter is as intclligiblejas the Union of one part of Matter 
withanother>
