PREFACE.

THE motive which has drawn forth this small work is, it is believed, a very ordinary one, that of offering back again for the service of Truth, knowledge which has been pleasurably and gratefully gathered. In the present negative and transitional state of the Scientific World general approval is little hoped for; it is therefore only to the enlightened believing few, whose thoughtful experience has enabled them to appreciate the great magnetical revelation of the true Light of Nature, that the Author looks for encouragement to cheer his spirit, hesitating to pass on from this Introduction to a fuller and more open exposition of truths, bearing, as he conceives, on the highest and best interests of the Human Race.
