X. An Account of fome Magnetical Experi- 
ments made before the Royal Society, on 
Thurfday the 24th *Day of June 1736. 
by the Rev d - J. T. Deiaguliers, LL. 2 ). 
F. R, S. 
I Took a Bar of Iron, of one fourth of an Inch Dia- 
meter (which having been if Years in an ered 
Pofition, had acquir'd a fix'd Pole at Top, fo that the 
End which had flood uppermoft attracted the North 
End of a Compafs-Needle, and the other End the 
South End of the Needle) j and having fufpended it 
by a String for the Space of half a Year, it acquir'd 
a fix'd South Pole at that End, as well as it had done 
at the other in the Time of if Years, without dimi- 
nifhing the Virtue of the other End : So that both 
Ends of the Rod in any Situation attraded the North 
End of the Needle of the Compafs. 
That Rods of Iron untouch'd, or which have not 
acquir'd a Magnetic Virtue by their Situation, will 
with their upper End (whatever End of the Bar be 
held upwards) attrad the North End of the Needle, 
and the lower End of the Bar the South End of the 
Needle, is a Truth known many Years ago, and men- 
tion d in Dr. Browns Book of vulgar Errors.
