1* A Trutifecf BODIES, Chap. 4, 



On the other fide, if -a den 'c thing be applyed to a com- 

 pound, it will ( becaufe ic is we ; ghty ) prefle ic together : and 

 ifthat application be continued on all fides, fothat no part of 

 the body that is prcfTed be free from the fiege of the denfe body 

 that prefleth it, ic will form it into a narrower room, and keep 

 in the parts of it, not permitting any of them to flip out. So 

 that what things foever it findeth within its power to mafter, 

 be they light or heavy, or of what contrary natures focvcr, it 

 compieffeth them as rm:ch as it can, and draweth them into a 

 lefle compaflTe, and holdeth them ftrongly together, making 

 them flick faft to one another. Which eflreft, Ariftotlc took 

 for the proper notion ofcold; & therefore gave for definition of 

 the nature of it, that it gathereth things of divers natures: 

 and experience flicweth us in frecfing, and all great coolings, 

 that this effect proceedeth from cold. 



5. But if we examine which of the two forts of denfe bodies 



of the two A. nc fluidc or the confiftant ) is mofr efficacious in this opera-

the icflc dcnfe tion ; we (hall hnd that the lelie denfe one is more capable of 

 but of^hemo being a ppty c d round about the body it fhall befiege; and there- 

 fore will ftop clofer every little hole of ic, and will more eafily 

 fendfubtile parts into every little vein of it ; andbyconie- 

 quence, fhrink it up together and coagulate, and confrrmge it 

 more ftrongly, then a body can that is extremely denfe 5 which 

 by reafon of its great dcnfity , and the ftubborncfTe of its parts, 

 cannot fo eafily bend and plie them to work this erTeft. And 

 therefore, a body that is moderately denfe is colder then ano- 

 ther that is fo in excefle; feeing that cold is an a6tive or work- 

 ing power, and that which is lefle dcnfe doth excell in work- 

 ing- 



On the contrary fide, rare bodies being hot, becaufe their 

 fubtile parts environing a compounded body will fink into the 

 pores of it, and to their power feparatc its parts ; it followeth 

 that thofe wherein the gravity ovcrcomcth the rariry, are lefle 

 hot then fuch others as are in the extremity, and higheft cxccfTc 

 of rarity : both, bceaufe the former are not able to pierce fb 

 little parts of the refitting denfe body , as extreme rare 

 ones arc; and likewife, becaufe they more eafily take ply by 

 the obftacle of the iolide ones they meet vmh, then thefe 

 do.
