I ?'7 ) 
I remember, that in my younger Days I once diverted 
myfeif with making an horizontal Needle, ’and a Dial- 
Box for it, one of my School-fellows having a Load- 
ftone. Before I could have the Ufe of the Stone, I 
often held my Needle within its Box, fometimes with 
its intended South End towards the Bottom of a Window 
Bar (having lately feen one of my Companions try it 
with his Pocket Needle, which was touched) and at. 
other Times I would hold the Needle’s North End at 
the Top of jhe Bar. 1 obferved the Needle, which 
was hung very tender, to make Vibrations at either 
End of the Bar. 1 happened to fet it down in the 
Window at a good Diftance therefrom, and found the 
South End more inclined to vibrate to the Bar’s Bot- 
tom than the North End, and feeing it to have fome 
Vertue, 1 thought of encrealing it by takingtheNeedle 
out of the Box, and applying it to touch the Bar with 
its proper Ends, By this Method alone it gained fuch 
a Degree of Polarity as would conftantly turn its pro- 
per End to the North, if it was kept trembling; but 
if I placed its contrary End to the Bar, the Polarity 
would be changed prefently. By this Way of Ma- 
nagement r could give it but a faint Verticity, which 
was loon more vigorous when I got the Ufe of the 
Stone, though it was fmall, and not of the bell, and 
the Needle foft Iron. And this was all, at that Time,. 
I knew of Magnetifm, having never read the particular 
Properties of the Stone, nor feen one before, nor heard 
of the untouched Needle’s Verticity,. or its vibrating to 
a Bar. 
Having within the Space 'of a- few Years pafl 
had a frelh Inclination to make fome magnetical Experi- 
ments,,
