Tenthly, I likewise indeavour'd to make it Shine, by holding it a pretty
while in a very Dark place, over a thick piece of Iron, that was well
Heated, but not to that Degree as to be Visibly so. And though at length I
found, that by this way also, the Stone acquired some Glimmering, yet it
was less than by either of the other ways above mention'd.
Eleventhly, I also brought it to some kind of Glimmering Light, by taking
it into Bed with me, and holding it a good while upon a warm part of my
Naked Body.
Twelfthly, To satisfie my self, whether the Motion introduc'd into the
Stone did generate the Light upon the account of its producing Heat there,
I held it near the Flame of a Candle, till it was qualify'd to shine pretty
well in the Dark, and then immediately I apply'd a slender Hair to try
whether it would attract it, but found not that it did so; though if it
were made to shine by Rubbing, it was as I formerly noted Electrical. And
for further Confirmation, though I once purposedly kept it so near the hot
Iron I just now mention'd, as to make it sensibly Warm, yet it shin'd more
Dimly than it had done by Affriction or the Flame of a Candle, though by
both those ways it had not acquir'd any warmth that was sensible.
