into this I put a piece of Loadllone, which was half as long again 

 as thick, but before inclofing it I carefully examined, by the help 

 of a fea-compafs, in what part its North pole was fituated ; and 

 finding it to be, not at the extremity but rather towards the middle, 

 I placed the Loadllone upright on its end in the glafs. The top of 

 this glafs, when it was put into the water with the Loadllone in it, 

 fcarcely appeared above the furface, and, after moying it in feveral 

 directions, I found that it would not remain at reft until the North 

 pole of the Loadftone in it pointed to the North. 



When this glafs with the Magnet in it floated in a ftate of reft on 

 the water, I took a piece of iron, almoft eighteen inches long, one 

 extremity of which I approached firft to the furface of the water, 

 and then to the outfide of the wooden vellel near theljottom, about 

 the part where the Magnet lay, in order to fee whether by this the 

 glafs containing the Magnet woidd be put into any new motion, but 

 I did not at that time perceive any. 



After this I applied the fame iron, not by its end but the vi^iole 

 length of it, as clofcly as poffible to the wooden veftel, and immedi- 

 ately I perceived that the glafs inclined feme what towards it, where- 

 vipon I llowly moved the iron roimd the box, and faw that the Load- 

 ftone in the glafs, and which was fourteen inches imder water, fol- 

 lowed the motion of the iron, fo that in nearly a minute's time it 

 performed a complete revolution. By this experiment the tendency 

 of the Magnet was proved to be greater towards the iron than to- 

 wards the North part of the heavens, as appeared by its following 

 the motion of the iron. Tlien, after fome interval, I placed the iron 

 length wife, clofe to the wooden box or veflel, in order to fee whether 

 the Loadftone would be attracted by the iron, towards the fide next to 

 it, which however did not happen, for it kept its pofition unmoved, 

 excepting only that its North pole altered its pofition a little from 

 the North. 



Afterwards I made another glafs, wherein I put a fragment of 

 Loadllone, which glafs was of the fame ftiape as that reprefented at
