I fancied in fome places, that one fide of the Wire would 
be attracted, the other repelled by one and the fame Pole 
of the toadftone^ 
To thefe odd changes, I could add divers others, which 
the Tvptfi'wg produced. But thefe do fufficiently (hew that 
the Magnenck Virtue is put into great confufion h\ the 
Violence exerted nipon the Vv'ire by Twifting : Whi^h not 
only feparateth the fibres of the Iron fas may be feen with 
the Eye, efpecially^ aflifted with a Microfcope ) but alfo 
changeth their Situation from Longways to Skrew-ways. 
This being the Succefs of Twljiing^ I was next minded 
to try what^ would be the iffue of Splitting or Clcavirrg 
touched Wires : Particularly whether they would exert the 
fame elFeds that Magnets are faid to do, when fawn in 
two Meridionally. Concerning which Dr Ridlej faith, 
> " Cut a piece from a Magnet ftone Mendionally, and that 
^ " end which was placed S. when it waa whole, being fe- 
' " vered, will turn North, although naturally at firft it was 
" the S. point. But Mr Barlow ( who feems to have been 
a more judicious and faithful Author, is of a contrary mind, 
and faith, That the Poles of fuch a piece of Magnet, when 
fevered, will abhor the fame Poles, to which it grew in 
the whole Magnet, But he fubjoyns, But here you muft 
" beware of an error, which fome unhappily have entan- 
" gled themfelves withal, who beholding the aforementi- 
" oned difcord, wrongfully fuppofed, that if both thefe 
Magnets the greater and the lefs [i. e. the piece cut 
off 3 were conveniently placed to fwim in Water, the 
" little one woiild not with his end point unto the South of 
" the Earth as it did in the Magnet being entire, when it 
" was a part of the true North- end, but would point contra- 
*^ rily. There is (faith he) no manner of any fuch altera- 
tion,but that both the great one, the little one, ( and all 
" the like, that are cut Meridionally one from another) v/ill 
"abfolutely point the very fame way which the entire one 
" did. Only the Meridian will be fomewhat removed, &c.
