for one another before conjunction;
wherefore also they are turned round to the corresponding ends, if they can
[not][181] reach them through the hindrances.

If a loadstone be divided through a meridian into two equal parts, the
separate parts mutually repel one another, the poles being * placed
directly opposite one another at a convenient and equal distance. They
repel one another also with a greater velocity than when pole is put
opposite pole incongruously. Just as the part B of the loadstone, placed
almost opposite the part A, repels it floating in its skiff, because D
turns away from F, and E from C; but if B is exactly joined with A again,
they agree and become one body {101} magnetical; but in proximity they
raise enmities. But if one part of the stone is turned round, so that C
faces D and F faces E, then A pursues B within its orbe until they are
united.

The Southern parts of the stone avoid the Southern parts, and the Northern
parts the Northern. Nevertheless, if by force you move up the Southern cusp
of a piece of iron too near the Southern part of the stone, the cusp is
seized and both are linked together in friendly embraces: because it
immediately reverses the implanted verticity of the iron, and it is changed
by the presence of the more powerful stone, which is more constant in its
forces than the iron. For they come together according to their nature, if
by reversal and mutation true conformity is produced, and just coition, as
also regular direction. Loadstones of the same shape, size, and vigour,
attract one another mutually with like efficacy, and in the opposite
position repel one another mutually with a like vigour.

Iron rods not touched, though alike and equal, do yet often act * upon one
another with different forces; because as the reasons of their acquired
verticity, also of their stability and vigour, are different, so the more
strongly they are excited, the more vigorously do they incite.

Pieces of iron excited by one and the same pole mutually repel * one
another by those ends at which they were excited; then also the opposite
ends to those in these iron pieces raise enmities one to another.

In versoria whose cusps have been rubbed, but not their cross-ends, * the
crosses mutually repel one another, but weakly and in proportion to their
length.

In like versoria the cusps, having been touched by the same * pole of the
loadstone, attract the cross-ends with equal s
