For iiippole the former Condenfed Subfiances to be now Rarefied, or the two firlt Barefied to be afterwards Contlcrilbd, then they will obtain greater or ICE " Diiuenlions, and coiifequently greater or leis places, Which are peculiar to each other, as they are encircled with proper furfaces of Air.

But perhaps fon‘ie may be {b curious as to make an inf‘peciion into the Eco. nomy ol‘ Nature, in reference to Condenfation and Rarefaaion of Bodies, and by what condufls they are managed; unto which it may be thus replied, immanthat thefe motions are foinetiines governed by External, fometimes by In- gngliicvi‘rntgl ternal Principles, and fonietimes partly by External, and partly by Internal i Principles; and an Inflance may be had of Natures conduct in Condenfation and Rarefac'tion by External, when Blood the molt generous Liquor (as the fountain of Life) addI‘CHEtli it (elf by greater and leis Arterial Chan- nels from the Center to the Circumference, from the inward to the outward ambRachaaiRegions, wnere its greater fervour receiveth manifeft allays by the ambient rial Principles y ' . - - , Oil ‘XKCY‘ cold, and groweth more grofs and heavy, the plain effects of Condenfation; Bififimzmg and the Vital Liquor is alto afl'eétcd with this quality, when by too great a quantity, it lodgeth it felf into the fubfiance of the Body, as in Inflaminations, and ZCdematous Tumours, wherein the Blood is extraval‘ated in the interfiices of the Vellels, which defiroyeth its tone and Spirits by undue Stagnation; whereupon it gi'oweth grofs and condeiifed : And thefe Tumours 2,32,‘,',‘f,$§j :gfl'fifijficbis t «y iiiami-nciiiéi Sniffing! are Cured often by Blood-letting, and hot Fomentations, and the making good the motion of the Blood, giveth it tone and thinnefs of parts, whence arifeth Rarefaaion, rendring it fit for local motion. lint theVital Liquor is governed by.Inward Principles, when by a clue $555293"; FCI‘H'IL‘DIREL‘D, confifling of Volatil, Saline, and Sulphureous Particles, ex- §;if1‘:;‘;‘cdina alth and' rarefied, as it is infpired with thin fpirituous fubfiances, giving Life ducfu'menration of and Motion.
