ingtlie South End of the other, and adhering by their 
magnetick Vertue, 1 placed the two Magnets, as be- 
fore, at their conjund Middle (not letting them re- 
main there a Moment) and then inftantly and fpeedily 
drew one Magnet to one End of the Wires, and the 
other Magnet to the other End of them ; by which 
Method I touched them, as it were, all at once, and 
as if they had been but one entire long Wire. I found 
this Way not only more expeditious, but more advan- 
tageous, giving all of them a ftronger Touch: But the 
Wire at each End was not fo ftrongly touched as the 
reft ; therefore I placed more Wires in the Trench than 
I had Occafion for, and laid afide thofe at each End, 
whofe Vertue was weaker. One of tliefe Wires, when 
it was thus newly touched, would lift a prepared Nail 
4.7 s Inches long, in Weight froy 3vij Gr. vj or vij 
(/. ^.) more than 4^6 Grains. The Weight of the 
Wire can be had in that of the Nail ii.sji times. 
1 placed all the 7 feparately in the magnetical Line for 
about two Days *, in which Time all of them had loft 
fome Vertue, yet one of them would with Difficulty 
lift the Nailaforefaid, which it lifted foinewhateafier 
juft after the Touch 5 and that which had loft moft 
Vertue, would eafily lift a Nail of 4 f Inches long, in 
Weight 306 Grains. 
Having fuch Succefs, I got feven round Bars of Steel - 
to be made, from End to End of one Size, fo that 
they would but juft go through a Hole made on Purpofe 
in a Plate of Iron, and tried their Lengths in a Standard 
as I did the others, and marked one End of each of them 
with the Corner of a File in this Manner, tT ) 
that I might be able to fee the Mark when they were 
bound together, left either of them ffiould be placed
