The fact correctly predicted by Molyneux, that those born blind but afterward surgically treated can not, by means of the eye alone, distinguish the form of a sphere from that of a cube, must accordingly be supplemented to this extent, viz., that such persons are capable, just as are normal children who can see, of learning this difference of form by means of the eye alone without the direct intervention of the sense of touch; for the co-ordination of the retinal excitations in space and time by means of the intellect, quite independently of all impressions from other departments of sense, is possible, and is in countless cases actual, just as is the learning of differences of form solely by means of the sense of touch in children who are born blind and never learn to see.

"This work is not intended for scholars or specialists, but for that large body of teachers throughout the country who are trying to do their duty, but are suffering from that want of enthusiasm which necessarily comes from being unable clearly to see the end and purpose of their labors, or to invest any end with sublime import. I have sought to show them that the end of their work is the redemption of humanity, an essential part of that process by which it is being gradually elevated to moral freedom, and to suggest to them the direction in which they ought to turn their chief efforts. If I can make even a few of them feel the consecration that comes from single-minded devotion to a great end, I shall hold that this book has accomplished its purpose."--_Author's Preface_. _THE EVOLUTION OF THE MASSACHUSETTS PUBLIC-SCHOOL SYSTEM. A Historical Sketch in Six Lectures_. By GEORGE H. MARTIN, A. M., Supervisor of Public Schools, Boston, Massachusetts. 12mo. Cloth, $1.50.
