end of the fbne which ir the earth lay towards the north pole, 

 will now in the aire convert it felf in the fame manner towards 

 the fame point; and the other end which lay towards the fouth, 

 turn by confequence to the fbuth. I fpeak of thefe countries 

 which lie between the equator and the north; in which it can- 

 not chufe but that the ftream going from the northto the equa- 

 tor, muft be ftronger then the oppofitc one. 



Now toexplicate.how this is done; fuppofe the ftone hanged 

 eaft and weft freely in the aire; the ftream which is drawn from 

 the north pole of the earth rangeth along by it in its courfe to 

 the equator; and finding in theftone the fouth fteam, (which 

 is grown innate to it) very ftrong, it muft needs incorporate it 

 {elf with it; and moft, by thofe parts of the ftcam in the ftone 

 which are ftrongeft: which are they that come direclly from 

 the North of the ftone; by which I mean that part of the ftonc 

 that lay northward in the earth, and that ftill looketh to the 

 north pole of the earth now it is in the aire. And therefore the 

 great floud of atomes coming from the north pole of the earth 

 will incorporate it felf moft ftrongly, by the north end of the 

 ftonc with the little floud of fouthern atomes it findeth in the 

 ftone : for that end ferveth for the coming out of the fouthern 

 atomes, and fendeth them abroad; as the fouth end doth the 

 northern fleam, fince the fteams do come in at one end., and do 

 go out at the oppofite end. 



From hence we may gather, that this ftonc will j'oyn and 

 cleave to its attractive, whenfoever it happeneth to be within 

 the fphereof its activity. Befides, if by fome accident it fliould 

 happen that the atomes or fteams which are drawn by the funne 

 from the Polewards to the equator, ftiould come ftronger from 

 fome part of the earth, which is on the fide hand of the Pole, 

 then from the very Pole it (elf; in this cafe the ftone will turn 

 from the Pole towards that fide. Laftly, whatfoever this ftonc 

 will do towards the Pole of the earth; the very fame a lefler 

 ftone of the fame kind will do towards a greater. And if there 

 be any kind of other fubftance that hath participation of the na- 

 ture of this ftone, fuch a fubftance will behave it felf towards 

 this ftone, in the fame manner, as fuch a ftone behaveth it felf 

 towards the earth: all the Phcnomens whereof may be the more 

 plainly obferved, if the ftone be cut into the form of the earth.
