by the Poles of the Magnet 5 whereas I faid they iifed- 
only to be attracted. Tiie next morning I trytd again: 
And then the Magnerifrn of the Wires was totally i^eftroy- 
edj as I related to the Society. This Experiment I repeat- 
ed divers times, and on divers Wires this Winter, and 
commonly find, that, all the day, coyling will evacuate the 
Magnerifrn: But that it will not abfolutely do it in the 
Evenihgs. But whether it will do fo in Summer, or all 
Weathers, or whether it fucceedeth thus only in different 
times of the Day, I muft leave to farther Tryals. I well 
know that the Orb of the Aftivity of Magnets, is larger, 
or lefs, at different times. That noble Magnet in the So- 
ciety's Fvepofitory found in Devout/hire by Dl: Cotfo^^ is 
known in fome Weathers (or at feme times) to keep a Key, 
or other piece of Iron^ fufpended to another Iron at 8, 9 
or 10 foot diftance. But at other times, the Iron will 
drop down at the diftance of 5 or 4 foot from the Mag« 
net, if ! lived nearer, 1 would obferve the ^h^rsomenoK 
more nicely : Particularly whether there be any difference 
therein in the Evening, and the reft of the Day* No\r 
whether at allj or how far this may reach the forementi- 
oned cafe, I cannot fay, not having as yet fufEciently ex- 
perimented the matter. 
Finding the cafe thus with Coyled^ or Bent Wire^ I waf 
minded to try the event of Tivlfiing of Iron Wire from end 
to end, after it had been well Touched, The Succefs 
was, The Vertkity was always weakened, and fometimes 
inverted* And when it was fo, the Load-ftone did ac- 
cordingly commonly Repel or Attract, all one as if the 
Twifting the Wire had given a new Touch the contrary 
way. 
^ But in fome Wires fo twifted, the Vcrticity was wholly 
d'eftroyed, or rather much confufcd. For 1 found by draw- 
ing one of the Poles of the Loadftone along near the fides 
of the Wire, that in fome peaces it would Attraft, in orhers 
Repel, and fo attra^ and repel all along the Wire. Nay,
