Illusions:
A Psychological Study. By James Sully, author of "Sensation and Intuition," etc. 12mo. Cloth, $1.50.
"An interesting contribution by Mr. James Sully to the study of mental pathology. The author's field of inquiry covers all the phenomena of illusion observed in sense-perception, in the introspection of the mind's own feelings, in the reading of others' feelings, in memory, and in belief. The author's conclusions are often illustrated by concrete example or anecdote, and his general treatment of the subject, while essentially scientific, is sufficiently clear and animated to attract the general reader."—New York Sun.
The Brain and its Functions.
By J. Luys, Physician to the Hospice de la Salpêtrière. With Illustrations. 12mo. Cloth, $1.50.
"No living physiologist is better entitled to speak with authority upon the structure and functions of the brain than Dr. Luys. His studies on the anatomy of the nervous system are acknowledged to be the fullest and most systematic ever undertaken. Dr. Luys supports his conclusions not only by his own anatomical researches, but also by many functional observations of various other physiologists, including of course Professor Ferrier's now classical experiments."—St. James's Gazette.
The Concepts and Theories of Modern Physics.
By J. B. Stallo. 12mo. Cloth, $1.75.
"Judge Stallo's work is an inquiry into the validity of those mechanical conceptions of the universe which are now held as fundamental in physical science. He takes up the leading modern doctrines which are based upon this mechanical conception, such as the atomic constitution of matter, the kinetic theory of gases, the conservation of energy, the nebular hypothesis, and other views, to find how much stands upon solid empirical around, and how much rests upon metaphysical speculation. Since the appearance of Dr. Draper's 'Religion and Science,' no book has been published in the country calculated to make so deep an impression on thoughtful and educated readers as this volume.... The range and minuteness of the author's learning, the acuteness of his reasoning, and the singular precision and clearness of his style, are qualities which very seldom have been jointly exhibited in a scientific treatise."—New York Sun.
