ocs in the water, without thruflingone another out of it. 



Laftly, this doctrine giveth no account why one part of fait 

 is fcparatcd from another by being put in the water, and why 

 the parts are there kept to fcpirated, which is the whole erfec} of 

 that motion which we call diflblution. 



10. The true reafon therefore of this effect, is (as I conceive) that 



The tmc rcafon one f a j t maketh the water apt to receive another; for the lighter 



of the lonr.cr , . . . . i i i i i t 



tffi.ft. . fait being incorporated with the water, maketh the water more 

 proper to flick unto an heavier, and by dividing the fmall parts 

 of it to bear them up,that otherwife would have funk in it. The 

 truth and reafon of which will appear more plain, if at every 

 joynt we obferve the particular fteps of every fairs folution. As 

 loon as you put the firft fait inco the water,it falleth down pre- 

 fently to the bottome of it; and as the water doth by its humidi- 

 ty pierce by degrees the little joynts of this fak, (b the fmall 

 parts of it are by little and little feparatcd from one another,and 

 united to parts of water. And io infufing more and more fait, 

 this progrefle will continue, untill every part of water is incor- 

 porated wirli fome part of fait :and thcn.thc water can no longer 

 work of it ftlf but in conjunction to the fait with which it is 

 united. After which, if more fait of the fame kind be put into the 

 *vater;that water fb impregnated,' will not be able to divide it ; 

 becaufe it hath not any ib fubtile parts left, as are aWe to enter 

 between the joynts of a faltfo clolcly compacted : but may be 

 compared to that fait, as a thing of equall drineflc with it j and 

 therefore is. unapt to tr.oiilen and to pierce it. 



But if you put into this compound of fait and water, another 

 kind of fait that is of a ftrongerand adder nature then the for- 

 mer, & whofe parts are more groflely united; then the firft fait 

 dilToivcd in the water, will be able ro get in betwixt the joynts 

 of the grofler frlt;& will divide it into little parts; and will in- 

 corporate his already compofed parts of fait and water into a 

 decompound of two fairs and water;nntill all his parts be nncw 

 impregnated with the iccond groflcr falt;as before, the pure 

 ter was with the fir ft fubtiler lair. And fo it xvill proceed on, if 

 proportionate bodies be joyned, untill the "dhToIving competi- 

 tion do grow into a thick body. 



Unto which dilcourfe we ir.ry r.ddctl-at when the water if Co 

 fully impregnated with the fliil fait,, as i: y\ ill receive no more,
