forthatthe Inrpulfion being the fame inboth; where there isagreater 
quantity of Water, and likewife {pace enough, there the Water roulech, | 
and moveth, both more flowly, arid with a floper rife and fall: But where 
there is lefs Water, and lefs fpace, and the Water datheth more againftthe 
bottom; there it moveth more fwiftly, and more jn Precipice: For in the | 
breaking of the Waves, there isever a Precipice. iat De 
[tf hath been obferved by thee Ancients, that Salt-warer boiled, ot boiled | 
and cooled again, is more potable, than of itfelf raw ; and eyeethe tafte | 
of Salt, im Diftillations by Fire, rifethnot : For the Diftilled Water will be | 
freth. The caufe may be, forthat the Salt part of the Water, doth partly } 
rife intoakinde of Scum onthe top, and partly gocth into a Sediment in | 
the bottom; and fo israthera feparation, thanan evaporation. Butitis too | 
grofsto rife into a vapor; and fo isa bitter tafte likewife: For fimple diftil |

T hathbeen fetdown before, that Pits upon the Sea-shores turn into frefly | 
Water, by Percolation of the Salt through the Sand: Bur it is further | 
noted, by fome of the Ancients, that infomeplaces of Uzfrick, afteratime, | 
the Water in fuch Pits will become brakifh again. Fhe caufe is, for that} 
after atime, the very:Sands, thorow which the Salt-Water paffeth, become | 
Salt j and fo the Strainer itfelf istin¢ted with Salt. Theremedytherefore is | 
to dig ftill new Pits, when the old wax brackifh; as if you would change |

| 
be, forthat the Salt inthe precedent Water;doth by fimilitude of Subftanees|
