that as tongas itboylcth, ic is in a perpetual! confufed mo- 

 tion up and down. Now having formerly concluded that/rr 

 light, find tight is fire ic cannot be doubted but that the 

 funne doth ferve in ftead of fire to our globe of earth and wa- 

 ter, (which may be fitly compared to the boylingpoc ) and 

 all the day Jongdraweth vapours from thofe bodies that his 

 beams ft rikt upon. For he ftiooting his little darts of fire in 

 multitudes, and in continued ftrcams from his own center a- 

 gainrtthe Python the earth we live on; they do there overtake 

 one another, and caufe fome degree of heat as far re as they 

 fink in. But not being able f by reafon of their great expanfi- 

 on in rhtir long journey) to convert it into their oA-n nature 

 and fee it on fire > (which requircth* high degree of condenfati- 

 on of the bearns)they do but pierce & divide it very fbtilly 3 and 

 cot fome of the outward parts of it into extreme little atomes. 

 Unto which they flicking very clofe, ^nd being in a manner 

 incorporated with them ( by realbn of tire ntoyftare that is in 

 them ) they do in their rebound back from the earfh carry 

 them along vfhh them; like a ball that /truck againft. a moift 

 wall, doth in its return from it , bring back fome of the mor- 

 tar iticking upon it. For the difhnce of tire earth from the 

 fun is nbt theutmoft period ofthtfc nimble bodies -flight; fo that 

 when by this folid body they are flopped in their courfe forwards 

 on,they leap bade from it, and carry fomc little parts of it with 

 them: fome of them 'a farther, fbmc of them a '(hotter journey; 

 according as their littlcncfle and rarity make them fitto aiccnd. 

 As is manifeft by the conrfcnt of all Authours that write 'of the 

 regions of the aire ; who determine the lower region to reach 

 fane 'as the reflexion -of the fimne; -and concladethis re- 

 gion to be very hot. 



For if we mark how the "heat -of fire is-grcareft, when it is 

 incorporated rn ibme denfe body ; '(as in iron or in fea-coal ) 

 \ve fhall ealily ccnrceivc that the heat of this regron proceedcth 

 mainly out of the incorporation of ligiit with tbofc Irttlc bo- 

 dies which ftrcTc ro it in its reiRexion. And experience tefrifieth 

 the htne, both in our foultrychyes,' which wefware of a groife
