Afwer to form Magnetical Inquiries , propojed Numb. 23, 
oftfe/e. Tranfaftions, Pag. 423, 424; 
The Queries were thefe. 
1. Whether a Needle may be fo toucht upon any Magnet, as 
sot to point to the true North and South ? &c. 
2. Whether different Load-Stones , will give different dire- 
Cf ions ? or, whether fainter or ftronger touches, upon one and 
the fameMagnet,will caufe any Variation in the directions? 
To thefe the Induftrious Mr. Sellers returns this Anfwer : 
To the Firfly That he had often made tryal with many 
Needles touching them in each Hemifphere of the Stone, with all 
variety of way es he could imagine,to find, if it were poffible by 
that means to caufe any of thefe Needles to vary in its direction 
but) that he alwayes found the contrary 5 all of them conform- 
ing to the Magnetic&l Meridian, , and handing North and South , 
as other Needles , that were toucht upon the very Vole of the 
Stone. He adds , that fome of thefe Experiments he tryed in 
London, when there was no Variation known. 
To the Second , i. That, upon frequent tryals of touching 
Needles upon different Load-Stones , of feveral bignefles, as alfo 
of different vertue , the feveral Needles , touched upon thefe 
different Stones, gave all of them the fame dire&ions. This he 
thinks is confirm’d by all the Needles and Sea- Compares , made in 
feveral parts of the World, and confequently touched upon fe- 
veral Stones of feveral Countries, yet all agreeing in this Mag - 
mtieal Harmony. that they all give the fame directions. 2. That 
having fometimes drawn a Needle 0 on\y over the Pole of the Stone, 
within the Sphere of its vertue , without at all touching the 
Stone, it hath received the fame directive quality from the 
Stone, as if it had been really toucht upon the Stone it felf, 
though not altogether fo ftrong, as if it had toucht the Stone, 
Again, that having toucht Needles upon the Stone, with faint 
ftrokes, and other Needles with ftronger $ all thefe Needles re- 
ceived the fame effeCt from the Stone, both forftrength and di- 
rection 5 he conceiving, that Vis not the fainter or ftronger touch- 
es upon the Stone, nor the multiplicity of Strokes, that varies 
the Needles ftrength or direction , but that the Nature of the 
Steel whereof the Needle is made, and the temper that is given 
thereunto.
