Middle of its length, and for that Reafon r fet it an End' 
in the Glafs, and, upon Tryal, I found that the Glafs 
would not ceafs turning in the Water till the North Side 
of the Bit pointed North- 
Whilft this Glafs ftood flill in the Water, I tryed with 
an Iron about li Foot long, by holding it above the 
Surface of the Water, as alfo on the outfide of the 
little Box, clofe by its Bo'.tom to fee whether it would 
move the Glafs ; but it had no tffz6t to draw it Side- 
wards : But doing the fame to fee if it would turn, I 
found that it did turn to the Iron ftronger than to the 
North, though it hanged Fourteen Inches under 
the Water. I try'd alfo by holding the Iron endways 
to the litile Bex to fee if it would draw- the Glaft 
to it, but it did not but only the North of the 
bit of Magnet did change its Pofition as to the 
North. 
Farther, I placed another little Glafs (including a 
bit of Magnet in it ) as Fig. 6, R. S. in a beer- 
Glafs, which I had till'd with Water above its Brims, 
and when the North of the Bit was fetled North, I ap» 
plyed a round Iron, about an Inch Diameter, as before, 
j clofe by the Side of the Beer-Glafs, and it turned the 
I little Glafs from the North as before, but it did not yet 
j make its approach toward the Iron. Th;s Turning of 
I the Glafs was in about half a Minutes Time. 
Fardier I placed the little Glafs near the fide of the 
Beer-glafs, to fee if it would then approach the Iron^ 
but it did not. Then I blew another little Glafs, as 
Fig. 6. incloling a bit of Magnet of about the weight 
of an ^j;, buc 1 found the efPefl of it miuch as the 
former (with the bigger bit of Magnet) only with this - 
difference : That the bigger bits did operate at the 
greater diflance*
