 * A Treatise of the Activities and Nature of the Mind from the Physical and Experimental Point of View. By GEORGE TRUMBULL LADD, Professor of Philosophy in Yale University. 8vo, $4.50.

This is the first treatise that has attempted to present to English readers a discussion of the whole subject brought down to the most recent times. It includes the latest discoveries, and by numerous and excellent illustrations and tables and by gathering material from scores and even hundreds of separate treatises inaccessible to most persons it brings before the reader in a compact and yet lucid form the entire subject.

The work has three principal divisions of which the first consists of a description of the structure and functions of the Nervous System considered simply under the conception of mechanism without reference to the phenomena of consciousness. The second part describes the various classes of correlations which exist between the phenomena of the nervous mechanism and mental phenomena, with an attempt to state what is known of the laws which maintain themselves over these various classes. The third part introduces, at the close of these researches, the presentation of such conclusions as may be legitimately gathered or more speculatively inferred concerning the nature of the human mind.
