that it was not pdfiible to find the Point where the Nee-' 
die would ftand indifFerently in any pofition, which 
Point wQuld have exadly mewed me the Pole of the 
Stone ybut that the Needle however placed,always direft' 
ed it felfCome one way. I determined by this means, as 
well as I could, the Point called the South Pole; but I 
was much furprifed to find it 18 Degrees diftant from a' 
Crofs deep engra.ven on the Stone, which according to 
all appearance had heretofore been the Pole of this Stone, 
as it had been Obferved by him that Gut it. This change 
of the Poles of this Stone having revived my former 
thoughts concerning the Variation of the Needle, I believ- 
ed that if it were true that the Poles of the MagneticaH 
Vertue changed in the Loadftone, as we fee they change 
in the Earth, one might derive great advantages there- 
from as to the Variations of the MagneticaH Needle. For 
if this change of thefe Poles ' in the Load-flohe were cer- 
tain, and that it was Analogous to the change of the Poles 
of the Magnetique Vertue in the Earth, it is not to be 
doubted but a A, being fufpended at Hberty, would 
remain immoveable, and that one point thereof would re- 
gard the Pole of the World,which might be called the true 
Pole oFthe ftbne,^ whilefl: the Poles of its Vertue would

been determined^; I cohcluded that this former Pole was 
diflant from the point I call the true Pole, thirteen De- 
grees towards the Eaff, in the place where it had been 
marked fand which is unknown to me J fince that at this 
timein this Country the Needle Varies about five De- -
