There is no essential power, whereby the air springs or moves [[underline]] itself, [[/underline]] and termed Elasticity of the Air; and to give it this property is denying that [[underline]] powerful Agent [[/underline]] which GOD created to perform the same office, and amounts to nothing less than denying the Works of GOD the Creator. Not one single instance was, or ever will be produced in favour of this absurd [[underline]] Newtonian compelling Force [[/underline]] in each particle of Air, which they say produces this elasticity; but what is meant by a [[underline]] repelling force [[/underline]] is entirely unknown to them as much as to the most illiterate, and their explanation of it is, That it is a Force whereby bodies may be said to be repelled; a fine explanation upon my word; but the misfortune is, it happens to be only in its own Terms, yet I think we ought to remain contented that it is not explained by terms more obscure than itself, if possible, as they often do. -- but to return -- The Air is expanded by [[underline]] heat [[/underline]] and condensed by [[underline]] cold [[/underline]], i.e. a less degree of [[underline]] heat [[/underline]]; thus by heating the Air [[underline]] plus [[/underline]] and [[underline]] minus [[/underline]] beyond its natural state it may be reduced to any degree of rarifaction or condensation it is capable of; therefore the medium of these, its natural state, must undoubtedly depend upon the degree of heat it then is impregnated with; so the elasticity is occasioned by the Agent of [[underline]] Heat [[/underline]] and not to move itself. W.J.
There seems to be something wonderful in the relation of an electric [[underline]] per se [[/underline]] and [[underline]] non electric [[/underline]] substances. The former are all artificial, except amber, and the latter Natural substances. Likewise those fluids which will not stop electricity will only dissolve [[strikethrough]] bodies [[/strikethrough]] non electric bodies; as, mercury only will dissolve Gold, Silver, &c. water, earthy substances, &c. Moreover, those fluids which stop electricity, as Oil, will not mix with those that carry it off, as water, &c. whence the different degrees or a different disposition of the Electric matter in bodies, which is elementary heat, seems to perform what the [[underline]] Newtonians [[/underline]] call Attraction of Cohesion. W.J.
W.J. cut a bit of spunge in a globular form and tied it to a wire, let thro' a collar of leather into a receiver, where stood a vessel of water; then he exhausted the receiver and let down the Spunge into the water placed in vacuo to drink in as much as it would, then carefully taking it out, the Spunge thread & water suck'd in, together, weighed 168 gr. These dipped in the same water in open air weighed 188 gr. and thence was carefully tied to the end of the wire, put into the receiver, and the receiver being exhausted, there drop'd water from the bottom until it became exactly of the same weight as before, when dipped in vacuo. The weight of the thread was 2 gr. & of the Spunge 18 gr. when throughly dry. - Hence what becomes of attraction of Cohesion, and what is it that keeps the particles of bodies together, this experi[men]]t shews [[strikethrough]] [[?]] [[strikethrough]] that, part is the pressure of the [[strikethrough]] Air [[/strikethrough]]  circumambient Air and the other is that of Light or Heat.
