An essay for the recording of illustrious providences

in his Book of the Usefulness of Experimental, ⟨p. 107⟩Natural Philosophy, Page 15. hath these words; Taking an Oblong Load-stone, and beating it red hot, I found the attractive faculty in not many minutes, either altogether abolished, or at least so impaired and weakened, that I was scarce if at all able to discern it. But this hath been observed, though not so faithfully related, by more than one; wherefore I shall add, That by Refrigerating this red hot Load-stone either North or South, I found that I could give its extremes a Polarity (if I may so speak) which they would readily display upon an excited Needle freely placed in equilibrium: And not only so, but I could by refrigerating the same end, sometimes North, and sometimes South, in a very short time change the Poles of the Load-stone at pleasure, making that which was a quarter of an hour before the North Pole, become the South; and on the contrary, the formerly southern Pole become the northern. And this change was wrought on the Load-stone, not only by cooling it directly North and South, but by cooling it perpendicularly: that end of it which was contiguous to the Ground growing the Northern Pole, and so (according to the Laws Magnetical) drawing to it the South end; and that which was remotest from the contrary one: As if indeed the Terrestrial Globe were as some Magnetic Philosophers have supposed it, but a great Magnes, ⟨p. 108⟩since its effluvium's are able in some cases to impart a magnetic faculty to the Load-stone it self, Thus far Mr. Boyle;
