draw fomewliat more Weight than before ; or if in 
an ered Poflure in North Latitude with the South 
Pole downward more, and upwards lefs than in an ho* 
rizontal Pofture : But thefe Differences are fo fmall 
as no Experiment I can think on will render fenfible 
in the leaff Degree, becaufe of the vaft Diftance be- 
tween the Surface of the Earth and the attradive 
Point of the internal Magnet : For fince Attradion and 
Repulfion are at the fame Diftance equal, I fay the one 
Pole of a Bar of Steel lo or 20 Feet long, di- 
reded toward the attradive Point of the Magnet, 
fuppofed at the Diftance of but one or two Miles, 
is not fenfibly nearer to it than the other (I mean in re- 
fped to Attradion) how much more infenfible then 
muft the far greater Diftance of looo Miles render it, 
which is notfo remote as Mr. Wktfion (Longitude and 
Latitude found by the Dipping-Needle, Pagm 48. 
Line fuppofes it to be. 1 cannot think fit to call 
the Point to which the Needle tends a refpedive Pointy 
as Mv, Norfnan does, fince his Experiments, Chaf,Y\. 
do not convince me (by reafon of the Diftance there- 
of from the Surface of the Earth) that it is not an at- 
tradive one. If therefore Steel after the Touch is ever 
found to weigh (with a Beam of Matter not magne- 
tical, and in a Place at too great Diftance from any 
Iron or Magnet to be fenfibly affeded thereby) either 
more or lefs than before, it muft be occafioned by the 
Augmentation or Diminution of its Quantity of Mat- 
ter by the Touch. The former feems impoflible, be- 
caufe a Magnet lofes no fenfible Weight by having 
10000 Pieces of Steel fucceffively touched on its Ar- 
mour j nor is the latter probable, unlefs the Weight 
of the Magnet is encreafed, or Part of the Subftance
