Mo ft of the known Properties of all Sorts of Mag^ 
nets which have been difcovered by the Obferva-> 
tions and Experiment s of fever al Perfofis^ inclu* 
ding one or two of my own, are the following, 
• 
I; That the Loadftone, by an invifible Force 
which differs froin that of Gravitation, and alfo 
of Eledricity, draws unto itfelf Loadifone, Iron, and 
’ Steel ; and with the fame Kind of Force, or Power, 
does not (atleafl very fenfibly) attrad any other Body 
whatfoever* 
II. That the Loadflone attrads Loadftone, Iron and 
'Steel with a polar Attradion, and that whatfoever At- 
tradion is not polar, is not magnetical. 
III. That the two oppofite Parts of a Loadflone 
attrad mofl vigoroufly, and are called theP oles thereof. 
The Middle between its two Poles doth not attrad at 
all, and may be called its /Tquinodial ; and from either 
Pole to the Middle, the attrading Force does gradually 
abate. 
IV. That in the fame, and every Loadflone, the 
one of its Poles is in Vertue (or rather in Diredion) 
contrary to the other, and therefore they need to be 
diftinguifhed from each other ; which is done by ad- 
ding North or South. The North-Pole of one Load- 
flone will not attrad, but repel the North Pole of ano- 
ther, though they are poffelfed of fimilar diredive 
Vertue^ neither will the South Poles of any two 
Loadflones attrad, but mutually repel one another: 
But the North Pole of one Loadflone, and the South 
Pole of any other, do mutually attrad each other 5 
and though their diredive Vertue is contrary, yet the 
unknown Caufe of their Attradion and Repulfion feems 
to be the fame.
