by it felf, where this divifion fhould be made, whether in the 

 parts of the bafin, or in the parts of -the water : and then, the 

 ether circtimflanccs determined ic in that part of the water 

 which was neareft to the joyning of it wich the bafin. 



The fecond eflfeft (which was refiftance to divisibility;) we 

 afTigned unto denfity. And of that fame caufe, rnuft allb depend 

 the like effect in this cafe of the flicking together of thetvvo 

 parts of different Elements, when they are joyncd to oneano- 

 thertfor if the two parts, whereof one is denfe, the other is rare, 

 do not exceed the quantity of fbme other part of one homoc- 

 neall rare Element for the dividing whereof, fuch a determinate 

 force, and no leiTe can fuffice: then/eeing that the whole compo- 

 ledofthefe two parts is not fo divifible as the whole confiftincr 

 of that one part ; the afTigned force will not be able to divide 

 them. Wherefore it is plain, that if the rare part had been join- 

 ed to another rare part indeed of the denfe one it is joyned 

 unto.. it had been moreeafily dividable from that, then now it is 

 from the dcnfe part. And by confequence it flicketh moreclofely 

 to the denfe part, then it would to another of its own nature. 



Out of what we have faid, a flep is made us to underftand 

 why foft and liquid bodies doeafily joyn and incorporate into 

 one continued body;but hard and dry bodies fo difficultly, as by 

 experience we find to be true. Water with water, or wine cither 

 with other wine or with water, fo uniteth, that it is very hard 

 to part them : but fand or (tones cannot be made to ftick toge- 

 ther without very great force and indurtry. The reafbns where- 

 of,rnuft ncccflarily depend of what we have faid above.To wit, 

 that two bodies cannot touch one another, without becoming 

 one : and, that if two bodies of one degree of denfity do touch, 

 they muft flick together according to the force ofthat degree of 

 dcnfuy.Out of which two., is manifcftly inferred,that if two hard 

 things fliould come to touch, they muft needs be more difficultly 

 feparatcd then n v o liquid tilings. And confequcntly, they can- 

 not come to touch, without as much difficulty, as that whereby 

 they are made one. 



But to deduce this more particularly; let us confidcr, that all 

 the little furfaces ,by which one hard body may be conceived to 

 touch another(as for example, when a flonc licch upon a ftoncj 

 inuit of neccftity be cither plain, or concavc ; or convex. Now
