And nowI molt humbly beg pardon for giving {b largely learned Doéi'or (3/; flit/1r, and my own Sentiments, relating to :1 Vacuum, which I. have taken all iillC‘ freedom to offer, becaule fome of this late Age, being given to No~ vclties, are beyond reafon fond of this opinion, a mere benne'rtz. Wherefore, I humbly conceive, I have good realon to believe that rare Bodies are not iiiterfpc‘i‘fed with Void Interfiices, becaufe their fiibiiance is highly extended, as having large Dimenfions tomprifed in a {mall portion of Matter, which is {0 far expanded, that it is every way commeniurate to the place in which it is repofed 5 and that very rare Bodies havmg great Expanlions, are bell-t with numerous lnterliices, which are not empty Spaces, but Pores and Cavities fraught with fubtle Bodies, as frothy Blood, contained in the interl‘tices and Cavities of the Pulmonary Veflels, is very much expanded; becaufe its numerous Pores are very much interfperled with the elalticlt particles of Air, and Vital Spirits, when the Lungs are very much extended in inipiration, in which the Cavities and Pores of the Brant/Jot and Veficles grow big, after they have received free draughts of Air. 1. are: m: llllt 0!] the other tide, Bodies are termed deiife, when they are compaft as » m i havingY a iiiorefolidConfifience, and as heavy Bodies have {mall Diinenfions "Hum" lodged in a great quantity of Matter, and thereupon have a more clofe Comfriiiiiiiiiiiii, page, as the bones of a Humane Body, which have minute Pores : And cor- a WW and I‘Ol‘cal Subfiances, are rendred Denfe, when their Pores and Cavities are """m‘?
