over by. And therefore we cannot doubt but that this floud of 

 atomes ftreaming from the pole of the earth, muft needs pafle 

 through that (tone with more fpeed and vigour then they can do 

 any other way. 



And as we fee in the running of water;that if it mccteth with 

 any lower cranies then the wide channel it ftreamech in; it will 

 turn out of its ftraight way,to glide along there where it findeth 

 an eafier and moredeelivc bed to tumble in: fo thefe atomes will 

 infallibly deturn themfelvcs from their direct courfe, to pafle 

 through fuch a ftone as far re as their greaterconvenicncy leadeth 

 them. 



And what we have faid ofthcfe atomes,which from the Poles 

 do range through the vaft fca of airc to the equator; is likewise 

 to be applyed unto thofc atomes which iffue out of the ftone: (o 

 that we may conclude, that if they meet with any help which 

 may convey them on with more fpeed and vigour, then whiles 

 they ftream directly forwards; they will likewife deturn them- 

 felvesfrom directly forwards, to take that courfe. And if" the 

 ftone it felf be hanged fo nicely that a lefie force is able to turn 

 it about then is requifitc to turn awry out of its coin 'c the con- 

 tinued ftream of atomes which itfueth from the ftoruerin this cafe, 

 the {tone it felf tnu ft needs turn towards thac.ftrearn which 

 climbing and filtring it (elf along the ftones ftream, drawcrh it 

 out of its courfe; in fuch fort as the nofc of a weathercock but- 

 teth it felf into the wind. Now then; it being known, that the 

 flrongcft ftream cometh directly from the north in the great 

 earth v & that the (buthern ft ream of the Terrclla or load-ftone 

 proportioned duely by nature to incorporate with the north 

 ftrcam of the earth, hTueth out of the north end of the ftone; it fol- 

 lows plainly that whenaloadftoncis fituated at liberty its north 

 end muft necefTarily turn towards the north pole of the world. 



And it will likewife follow, that whenfbcver luch a ftone 

 mecteth with another of the fame nature and kind, they murt 

 comport themfelvcs to one another in like fort: that is, if both of 

 them be free and eqtiall, they muft turn themfelves to, or fio=n 

 one another;nccording as they are fituated in refpccl of one ano- 

 ther. So that if their axes be parallel, and thefouth t;olt of the 

 one, and the north of the other do look the fame way,then they 

 \vill fend proportionate, and agreeing ftreams to one anocher
