A New System Explanatory Of Terrestrial Phaenomena, &C.
in consequence of the fact having been proved by means of the Triangular and straight Lines , existing in relief , on the surface of the first delineated Magnetic Stone , that the POWER works upwards from the Centre of the Ore , and does not confine the course of progressing through the Universe merely to the surface of the stratified Body . The Experiment is this . —Let N S ( Fig . 3 ) represent a Bar Magnet having a Magnetised Needlepoised in the vertical laneplaced above the
, p , Centre of the Bar marked +. So long as the Magnet remains undisturbed in the situation delineated , the Needle will continue with inverted Poles in the horizontal position s—n . But if the opposite Pole of a second Magnetic Bar be approximated to one of the Poles of the former , say at Pole S , an alteration induced by an apparent shift in the Polar point N , will instantl y be effected'in the horizontal Line of the Needle , which will Dip in the manner here represented . This fact then plainly
evinces , that the Centre , on the approach of the second Bar , has shifted from + to a point nearer S ; and that either a New Pole has been formed , or that the N 3 ' ole has , in corresponding manner , retrograded from N towards -f , or Centre of the first Magnet . The Reader , however , always preserving in mind , that the Centre beyond matter is unaltered , and is in no way affected by the Phenomena , which have been described ; a fact rendered still more strikingly evident from the circumstance of the
POWER of the Pole in N continuing as strong as it was found previously to the approach of the second Bar . The Needle , upon removing the second Bar , instanter regains its former position , and remains , as at first , poised horizontally , being equally balanced between N and S . Similar , yet opposite effects are observed when the Magnets become reversed
( Fig . 5 ) , and the Poles in a contrary position are presented to each other ; or S N is made the relative situation of the two Bars . From the inferences , warranted by the foregoing experiment , and the variation , under certain circumstances , of the Changing Point , from a Central to a Polar , in the Mineral Magnet , we then arrive at the conclusion of the Magnetic Centre with reference to matter , so far as evidence derived from the corporeal senses , in this case , can be admissible , being moveableThis motion is testified in the above Experiment
. , as , advancing in a Circle from the Pole , or Cosine point of the Arc of aO towards the Centre , this latter being the point which coincides with the Needle Raphidean , or material point , posited in the extremity of the Axis , or Diameter , in the Circumference , and again passing from the Centre to the opposite Cosine point , in the bisection of the Second Radius ; these points regaining , when the inducing circumstauces are absent , their original situation in the Circle ( Fig . G ) .
The third fact , whose establishment is necessary in order to render these demonstrations convincing to the Reader ' s mind , is the testimony adducible from the Phenomena of the Magnetic Rocks , that the two visible Segments of the Magnetic Line , —the one Segment being the Line of no Variation on the Earth ' s surface , which terminates in the Terrestrial Magnetic Pole ; and the other , the Line of Mutation , or Magnetic Equator , running at Right Angles to the former ( as though
