I apy>liec 1 to the marked Ends of the Wires) in a rea- 
dinefsj I fpeedily did thruft them together into a Bun- 
dle, and calling the Thread x or 3 times round them, 
with my Fingers I formed the Bundle into a. regular 
Hexagon as foon as I could, and then bound them fad 
from End to End, and bound fall the Armour. I rook 
the Number 37, becaufe that would form a regular 
Hexagon at each End, and fowill alfo 19 or 7. Find- 
ing this arriticial Magnet exceed my natural one, I 
held the Artificial in one Hand, and the Natural in 
the other, the North Pole of the oneagainfl: the South 
Pole of the other, and placing their Armour on the 
Middle of one of my Wires, drew the Magnets afun-

Inflant. in that manner I touched one by one a fe-

and bound on the Armour of the firfl Set to the fecond. 
The South Pole lifted a Key, Weight sij 3 ij 3!]’ 
Gr. V. Both Poles united would, with Difficulty, 
lift the faid Key with Weights faftened to it, the 
whole tbj I next tried with 19 Wires, for 
which 1 made Armour of a proportionable Size; but 
that did not anfwer fo well, I thought, as 3 7, though 
I repeated the Touch. Afterward 1 took 7, which I 
thought performed according to its Quantity as well 
as the 37. Therefore 1 ever after ufed the Num-

In the next Place I thought of mending this Way of 
Touching, by placing all the 7, or more of them, 
with their marked Ends toward the North in a long 
fmall Trench, whofe Depth was jufl: fit for one of 
them, to keep it from rolling away while I was touch- 
ing it and its Fellows. The North End of one touch-
