**■ Handle $ and the Piece of Four Inches long, that 
“ was broke off, remained on the Shop-board. 
“ The next Day after the Accident, the Clock- 
* { maker, obferving that the remaining Part of this 
“ File might Bill be of Service to him, took it up, 
“ and worked with it. But he was much furprifed 
“ to lee, that Iron followed the End of his broken 
u File. He applied this End to a Punch (or Drill), 
“ and the Punch was immediately attracted to the 
“ File. He called to me, and 1 made feveral Trials 
<c of this attra&ive Quality. I took the Piece of the 
<c File that had been broken off, and applied it to an 
“ iron Ring for hanging Keys ; which it lifted up 
“ perfectly well, and held fufpended as long as I 
thought proper. I doubted not but it was the 
“ Lightning that had communicated a magnetic Qua* 
“ lity to this File; and I found, upon Trial, that this 
“ Quality was given only to the Infide of the File, 
u and the broken Piece ; for I. applied Bits of Iron to 
u every Side of it, without any Effeft, the Virtue 
“ refiding no-where but in the Place that was broken.-- 
u I broke in two the fame Piece of Four Inches and 
u one of the Two Pieces attracted Iron at both Ends, 
ct the other only at its broken End. I rubbed the 
“ Point of my Knife on one of thefe two Bits of 
“ the File, and it communicated to my Knife a De- 
<e gree of Magnetifm fufficient to raife Needles, and 
cc hold them fufpended.” 
I wifh, Sir, this Obfervation may prove agreeable 
to you: It will ferve at lead to multiply the odd 
EfFefts of Lightning, and the Wonders of Mag»- 
netifm.
