ning the Experiment 6 Inches nearer the Stone than the 
other : And from two Feet diftance from the fame, it 
became nearly agreeable to the Angles made by the 
long Needle to all the farther Diftances} as you will 
find by the following Tables, which were made with the 
feveral Needles in the fame direction of the Stone. I 
meafured the Angles by a Silk thread drained dire&ly 
over the Needle to that part of the Quadrant to which 
it was directed ^ which was the bed way I could con* 
trive to come neared the truth. 
ft may be obferv’d from the following Tables, that 
the long Needle at 9 Inches from the Stone, made fome. 
What a larger Angle than the Ihort Needle at 3 Inches 
diftance from the fame 3 that the (liort Needle at the di- 
dance of 9 Inches, made an Angle of 9 Degrees lefs 
than the long one at the fame place. But this odds will 
eafily be accounted for, if we confider the difproporti- 
ons of the Needles lengths 5 for the Point of the long 
Needle at 9 Inches, was brought within an Inch as near 
the Stone, as the Point of the Ihort Needle was, when 
but 3 Inches didant from the fame*. The Point of the 
fhott Needle at 9 Inches from the Stone, was 5 Inches 
farther from if, than the long one at the fame Station. 
Thefe djfpfoportiofis being confider’d, it is no wonder 
iuch difference of Angles fhould enfue upon the life of 
the feveral Needles near the Stone •-> for at two Feet, and 
the farther didances, they become nearly agreeable, as 
1 faid before; When I fpeak of Didances from the 
Needle, I always mean from the Center of it# 
Farther it is obfervable, that the Stone at 5 Feet d> 
dance from the Needle made an Angle of 2 Degrees 
with one, and with the other of two and a half $ yet up* 
on the abfenee of the Stone they would return to no 
Degrees,, as at fir ft : Which plainly (hews, that the Influ- 
ence of the Stone extended farther $ &tho’' Qbferv&ioiw, 
to remoter Stations, could not eafily be determined.
