Rarefaction

Illumination, Rarefaction, and Condensation, and all those other things, by which they influence these inferior Bodies, whereby they are dispos'd for the Reception of Spiritual Forms from the _necessarily self-existent

That they found no sensible Alteration as to the Rarefaction of the Air, and that the Cold was rather less intense.

Rarefaction succeeds condensation at an interval of one-half what we call “wave-lengths.

Rarefaction of air facilitates discharge, why, 1375.

_Rarefaction of the air_ wonderfully favours the glow phenomena.

Rarefaction of common air about a negative ball or blunt point facilitated the development of the negative brush, the effect being, I think, greater than on a positive brush, though great on both.

And from this Notion of it, we may easily give a more Intelligible reason how the Air becomes so capable of _Rarefaction_ and _Condensation_.

As in those of _Heat_, and _Light_ consequently of _Rarefaction_ and

This, had I time, I should enlarge much more upon; for it seems to me to be the very first footstep of _Sensation_, and Animate motion, the most plain, simple, and obvious contrivance that Nature has made use of to produce a motion; next to that of Rarefaction and Condensation by heat and cold.

And another, for the finding what pressure was requisite to make it pass from such a degree of Rarefaction to a determinate Density: Which Experiments, because they may be useful to illustrate the present Inquiry, I shall briefly describe.
