Finding my artificial Magnets, rightly ufed, would 
communicate more Vertue to other Steel than they 
themfelves had, and obferving that ereft Bars had fomc 
Vertue from the Earth’s Magnet, and having alfo ex- 
perienced that Iron, which had only tranfien tVertue, 
would, when in an ered Pofiure, or in the magnetical 
Line, give a fmall Degree of fixed Polarity. (J^ide 
fupra, Pag:^\7,) 
I ordered nine Steel Bars 0.75 of an Inch fquare, and 
1 6 Inches long, to be made. Some of them, through the 
Smith’s Fault, were a little lefs *, the Weight of the 
heavieft was, after it was finiflied, 3 ft Avoirdupois, 
1 made them moderately bright by grinding, and filed 
their Ends fo plain as I could, and tranfverfe to their 
Lengths, by help of a Carpenter’s Square ; then marked 
one End of them, and, when hardened, I fcowred them 
bright, and polifhed their Ends very well. I fitted a 
Piece of Armour for each End of one Bar, and mark- 
ed the Piece which was for the marked End of the 
Bar, and bound fall both Pieces of Armour to the fame 
Bar, one at each End : Then Handing with my Face, 
toward the Weft, and holding the Palm of my Left 
Hand upward, I placed therein one of the Bars without 
Armour with its marked End Northward, and grafped 
it fall: at its Middle, with my Fingers on the Weft 
Side, and the Bail of my Thumb on the Eaft Side, 
where I alfo laid along my whole Thumb to keep it 
fteady : So the upper Part of the Bar was open from 
End to End. Thus holding it, I elevated the South 
End thereof until I guelTed it was in the magnetical 
Line ^ and holding with my Right Hand the armed 
Bar, with the Poles of the Armour downward, and 
the marked End toward the North depreffed to the 
magnetical
