memory-formations and the acquired established connection of the elements of soul-life are reduced to the primitive state that obtains in the soul of a child, to whom life is in reality a dream without definite limits. I well remember from the period of my early boyhood, the peculiar sensation of a state flickering between reality and fancy, and I understand the condition of those primitive tribes with whom dreamland and life intermingle in the strangest way; but capacities in this direction have disappeared down to the striking want of a normally developed faculty for colors. * * * * * Summing up then, we may say, that with regard to their _contents_ the phenomena produced by the agency of the magic mirror proceed from the realm of subconsciousness; and that with regard to their _form_ they belong to the category of hallucinations. Their contents, not regarded as a performance of memory, appear to possess no great value—so grotesque and ordinary are the few ideas brought up from this invisible storehouse. But they often supply us with a deep view into the secrets of character, and inculcate with terrible emphasis the truth that nothing is lost in the realms of the soul, any more than in the external world which is ruled by the law of the conservation of energy. Every thought that ever traversed our brain, every emotion that has ever thrilled our heart, every wish that has ever animated for a fleeting moment our breast—has all been entered in ineffaceable characters in the day-book of our earthly existence. Would that this knowledge could strengthen our feeling of moral responsibility! Thus does the expansion of our psychological conceptions not infrequently lead to an enrichment of our notions of morality. But whether we place a higher value upon this aspect last mentioned, or upon the purely scientific object to which we referred at the beginning of our article, or finally upon a factor connected therewith, namely the enlightenment of society—at any rate we must confess that in the much abused "magic mirror" a rich and attractive source of treasures has been opened. MAX DESSOIR. HÖFFDING ON THE RELATION OF THE MIND TO THE BODY. Few topics are of greater speculative or indeed practical interest than that of the relation of the body to the mind. Rarely has the subject been treated with such perspicuity and at the same time with such candor and avoidance of hasty dogmatism as by Professor Harald Höffding, of Copenhagen, in his "Psychology" (translated into German from the Danish and published in Leipsic, Reisland). A leading American professor of philosophy remarked to me recently that this for its size (the volume contains 452 pages) was the best all-around work on Psychology; and an examination of the section entitled _Seele und Körper_ (Mind and Body) certainly gives countenance to the statement.
