touching the larger end of the adjoining egg ; while in the second (ordinary iron or steel), badly packed, the separate eggs lie in all sorts of positions with regard to each other, and at all angles of inclination to the sides of the box."*
Every particle of iron in an unmagnetized bar is supposed to contain equal quantities of two magnetic fluids, called positive and negative, which have a mutual attraction for one another ; but these fluids are intimately united in the particle and neutralize one another. This is one of the two theories of magnetism known to science. The other, known as the theory of Weber, is that the particles of iron are always magnetic ; that is, the extremities of every particle are always magnetic poles, but in the ordinary state of iron these poles are turned in all directions, so that they neutralize each other's effect. Magnetization, on the first hypothesis, is caused by the separation of the two fluids and their being pushed to the two poles; but, according to the second, is the effect of the re-arrangement of all the particles composing the bar, like the systematic arrangement of the eggs in the box, as described above.
Thus, whichever theory be regarded as correct, it is clear that the extraordinary, phenomenal powers of the magnet are the result of a systematic arrangement of the parts composing it, with regard to each other, and the sides of the box.' A similar change takes place in the human mind under the influence of Yoga. In the untrained state the power of the mind is neutralized owing to the bad arrangement of the particles of matter; but under the influence of Yoga, these particles are
