rnaining in the temper it is in ; yet if it be heated, ic will then z- 

 frcfh diflolve more of the fame kind. Which fhewet!i, that the 

 reafon of its giving over todiflblve, is for want of having the 

 water divided into parts little enough to ftick unto more lilt : 

 which, as in this cafe the fire doth; fopcrad venture in the oc!icr., 

 the acrimonioufneflcofthe fait doth it. 



And this is fufficicnt to give curious wits occafion by making j i. 

 farther cxperiments.to fearch out the truth of this mnttcr. Onely ^ c rcafon why 

 we may note what hapneth in moft of the experiencies we have fa^/nauire'do 

 mentioned; to wit, that things of the fame nature do joyn better J ;>'" n orc -

and more eafily then others that are more eitranged from one thcnothe r5 . 

 another. Which is very agreeable to reafbn; feeing that if nature 

 do intend to have things confift long together^Oie muft fit them 

 for fuch confiftence. 



Which fcemeth to proceed out oftheir agreement in fbure 

 qualities ; firft, in weight for bodies ofdivers decrees in weight, 

 if :hey be at libcrty.do feek divers places; and confequently fub- 

 ftanccs oflike weight, muft of neceffity find one another out, 

 and croud together ; as we hare Chewed, it is the nature of he*at 

 to make them do : now it is apparent that things of one nature, 

 muft in equall parts have the fame or a near proportion of 

 Weight, feeing that in their compofition, they muft have the 

 fame proportion of Elements. 



Thcfecond reafon of the confiftence of bodies together, that 

 are of the fame nature is, the agreement of their liquid parts, in 

 the fame degree of rarity and denfity : for as it is the nature of 

 quantity in common to make all parts be one quantity; fo it is 

 the nature of the degrees of quantity, when two parts do meet 

 that are of the fame degree, to make them one in that degree of 

 quantity;which is, to make them ftick together in that degree of 

 flicking, which the degree of denfity that is common to them 

 both, maketh of its own nature.Whereasjparts of different dcn- 

 fitks,cannot have this reafon of flicking: though, peradventure 

 they may upon feme other ground, have foinc more efficacious 

 one. And in this manner, the like humid parts of two bodies,be- 

 coming one, the holes or receptacles in which thofe humide 

 parts are contained mull alfb needs be united. 



The third rcafon is the agreeable proportion, which their le- 

 vcrall figures have in refpcft of one another: for if any humidi-
