magnetical Line, I placed the Pole of the upper Ar* 
mour about 4 or 5 " Inches from the Top of the un- 
armed Bar, and fo foon as ever it touched the Bar, I 
began, with the greateft Speed I could make, to draw it 
downward until I was pafl the Middle, and from 
thence to the Bottom gradually flower. When it was 
at the Bottom I permitted it to reft there about i or x 
Seconds. After the fame Manner applying the Pole of 
the lower Armour to the unarmed Bar about 4 or ^ 
Inches from its Bottom, 1 drew it upward, fpeedily 
at firft, flower when above the Middle, letting it reft 
a little at the Top. Having upwards and downwards 
alternately repeated the Touch on the fame Side 
of the Bar, I touched the oppofite Side thereof^ 
which was next my Hand, in the fame Manner, and 
afterwards the two other Sides. Then holding the 
unarmed Bar ered, I ufed to fee if it had gained any 
fixed Polarity by holding my fmall Needle at the Top 
and at the Bottom of the Bar ; for if it had gained 
any Vertue by the Touch, it would attradthe Needle 
ftronger, at the fame Diftance, when the marked End 
of the Bar was held downward, than when it was held 
upward. If I found it had gained any fenflble Ver- 
tue, 1 took off the Armour from the firft Bar, and 
bound it to the fecond which I had touched, and after 
the fame Manner touched the firft Bar with the fe- 
cond, as I had touched the fecond with the firft. 
And when by Trial with the Compafs Needle I found 
the armed Bar had communicated to the other more 
Vertue than was in itfelf, I took off the iVnnour and 
bound it to that which was newly touched, and 
therewith retouched that which I had difarmed. In 
a few Repetitions of changing the Armour from Bar 
to.
