Loadftones, each above a Pound weight, I hung one 
of them in a Ballance to fee if it would dip or bend to 
an Iron : but though I approach'd the Iron to theBallance, 
I could not find that any fuch dipping happened. 
Some curious Gentlemen having found fomewhat of 
this Dipping of the Loadftone to the Iron, and having 
informed me by Letter concerning it : I took one of my 
Loadftones to J what weight of Iron it would take up. 
Then taking the Key of my Door, which I carry ed a- 
bout me, I found that the Load-ftone could not fuftain 
it : but filing that part of the Key that touched the 
Srooe, thereby taking off the foulnefs or ud(9:uous Mat- 
ter left on it by handling, I found that it would be hC* 
tained by the Loadftone. This made me wonder the 
lefs that the Loadftone did not dip to the Iron in the 
former Experiment, And I faw that it was from the 
little Power of the Stone, when but a little feparated 
from the Iron, and not from the Defeds of the Scales, 
as I had then fufpeded. 
I have had one of m.y Loadftones broken by me fe- 
deral Years, in order to make fbrne Obfervations, 
but they have be^n hitherto ine{Ie<9:ua! : As when I 
took a Piece about the bigoefs of the Kernel of a Ha- 
zleNut, and (eai'd it up in a Glafs, I found it would 
work on the Compafs-Needle as well as out of the 
Glafs, Then I broke this Glafs, and put the fame 
Piece into .a Piece of a Glafs Tube; then blew the 
Glafs to inclofe Piece, and left Air enough in the 
Glafs to make it fwim, to try if it would^urn toward 
the North.

Piece of Loadflone. I put this to fWim on the Water 
in an Earthen Difb, and found that it did turn to the 
North, but the contrary Way : And though I took out
