locution. At the same time there is no affected juvenility of expression. The writer has drawn freely upon the best authorities, but he has written very little which has not been through the crucible of his own mind. Among the authors made use of, Dr. Hopkins is the most prominent, and his views have been largely, but not wholly, adopted. Dr. Porter, Dr. Hickok, Sir William Hamilton, Reid, Stewart, Fleming, McCosh, and many minor writers have been freely consulted. In the arrangement of topics the logical method has not been wholly followed, but rather the order in which the different phenomena present themselves to the mind. There are some faculties and powers of the soul upon which others are conditioned, and which, for that reason, might seem to demand prior consideration, but which are more subtle and abstruse, and less easily understood, than the others, and therefore were better deferred for later explanation and elucidation. Concrete illustrations. have been used so far as the limits of the work would permit, as the writer has learned by experience that abstract science without such instances is, to young students at least, of little value. The work is intended for a one-term study, with daily recitations. This will afford ample opportunity for special instruction, and for amplification on particular points. A knowledge of one's self is of the first importance from the beginning to the end of education; and a knowledge of one's self is essentially a knowledge of the powers and operations of the soul. That even a high school or academic education should conclude without a certain degree of such knowledge, would be a misfortune. At present our schools are seriously lacking in facilities for this study. Whether this attempt to increase these facilities will be successful, is yet to be determined. The author desires to acknowledge his indebtedness to Miss Louise M. Hodgkins, professor of English literature in Wellesley College, for the examination of manuscript, and to Professor Benjamin Gill, of Wesleyan Academy, for reading the proof-sheets, and to both for valuable suggestions.
