THE SUN. By C. A. Young, Ph. D., LL. D., Professor of Astronomy in the College of New Jersey. With numerous Illustrations. 12mo. Cloth, $2.00.
“Professor Young is an authority on ‘The Sun,’ and writes from intimate knowledge. He has studied that great luminary all his life, invented and improved instruments for observing it, gone to all quarters of the world in search of the best places and opportunities to watch it, and has contributed important discoveries that have extended our knowledge of it.
“It would take a cyclopædia to represent all that has been done toward clearing up the solar mysteries. Professor Young has summarized the information, and presented it in a form completely available for general readers. There is no rhetoric in his book; he trusts the grandeur of his theme to kindle interest and impress the feelings. His statements are plain, direct, clear, and condensed, though ample enough for his purpose, and the substance of what is generally wanted will be found accurately given in his pages.”—Popular Science Monthly.
[ILLUSIONS: A Psychological Study.] By James Sully, author of “Sensation and Intuition,” etc. 12mo. Cloth. $1.50.
This volume takes a wide survey of the field of error, embracing in its view not only the illusions commonly regarded as of the nature of mental aberrations or hallucinations, but also other illusions arising from that capacity for error which belongs essentially to rational human nature. The author has endeavored to keep to a strictly scientific treatment—that is to say, the description and classification of acknowledged errors, and the exposition of them by a reference to their psychical and physical conditions.
“This is not a technical work, but one of wide popular interest, in the principles and results of which every one is concerned. The illusions of perception of the senses and of dreams are first considered, and then the author passes to the illusions of introspection, errors of insight, illusions of memory, and illusions of belief. The work is a noteworthy contribution to the original progress of thought, and may be relied upon as representing the present state of knowledge on the important subject to which it is devoted.”—Popular Science Monthly.
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.
“Dr. Luys, at the head of the great French Insane Asylum, is one of the most eminent and successful investigators of cerebral science now living; and he has given unquestionably the clearest and most interesting brief account yet made of the structure and operations of the brain. We have been fascinated by this volume more than by any other treatise we have yet seen on the machinery of sensibility and thought; and we have been instructed not only by much that is new, but by many sagacious practical hints such as it is well for everybody to understand.”—The Popular Science Monthly.
