Cbap.ip. <A Treat ije of BODIES. 207 



The end of this operation is, when any water is mingled with 

 grofle and muddy parts (not diflolved in the water) to feparate 

 the pine and light ones from the impure.By which we are taught 

 that the lighter parts ofthe water.arethofe which moft ea-fily do 

 catch. And if we will examine in particular,how it is likely this 

 bufinefle paifeth ; we may conceive that the body or linguet by 

 \vhicb the water afcendeth, being a dry one, fome lightet parts 

 of the water, \vhofe chance it is to be near the climbing body of 

 flixe, do bfgin to fiick faft unto it: and then, they require no- 

 thing near ib great force, nor fo much preffing, to make them 

 climbe i;p slorg the flaxe, as they would do to make them 

 mount in the pine aire. As you may fee, if you hold a flick in 

 running water, fhelving againft the flream : the water will rua 

 up along ehe (tick, much higher then it could be forced up in 

 the open aite without any fupport,though the agent were much 

 flronger then the current ofthe ftream. And a bail will upon a, 

 rebound,run much higher upon a fhelving board, then it would 

 if nothing touched it. And I have been told that if an egslheil 

 filled with dew be fct at the foot ofa hollow flick, the fun wiK 

 draw it to the top of the fhelving ftick,whcreas without a prop, 

 it; will notflirrc it. 



With much more reafon then, we may conceive that water 

 finding as it werelittle fleps in the cotton to facilitate its jour- > 



ney upwards, muft aicend more eafily then thofe other things 

 do;/b as it once receive any impu lie to drive it up wards: for the 

 gravity both of that water which is upon the cotton, as alfo, of 

 fo many ofthe confining parts of water as can reach the cotton; 

 is exceedingly allayed, either by flicking unto the cotron,and fo 

 weighing in one bulk with that dry body ; or die, by not tend- 

 ing clown flraight to the center, but reiring as it u ere upon a 

 ftccp plain ('according to what we L\id ofthe arme o~a fyphon 

 thaehangeth very Hoping out of the water.and therefore draw- 

 eth not after it a Idfc proportion of water in the other arme that 

 is more in a direft line to the center :) by which means the wa-
