I know not whether I need annex that,
though either of the above-mention'd
Hypotheſes, and perhaps ſome others,
may afford us an account plauſible enough
of the Air-ſpring; yet I doubt, whether
any of them gives us a ſufficient account
of its Nature. And of this doubt, I
might here mention ſome Reaſons, but
that, peradventure, I may (God permit
ting) have a fitter occaſion to ſay ſome
thing of it elſewhere. And therefore I
ſhould now proceed to the next Experi

to ſuggeſt to your Lordſhip what comes
into my thoughts, by way of Anſwer to
a plauſible Objection, which I foreſee you
may make againſt our propoſ'd Doctrine,
touching the Spring of the Air. For it
may be alleadged, that though the Air
were granted to conſiſt of Springy Par
ticles (if I may ſo ſpeak) yet thereby
we could onely give an account of the
Dilatation of the Air in Wine-Guns and
