PSYCHOLOGY: From the Standpoint of a Behaviorist

By Dr. JOHN B. WATSON,

Professor of Psychology, Johns Hopkins University, Baltimore.

429 Pages. Illustrated. $3.00.

HIGH AND ADVANCED SCHOOLS.

A TEXT FROM THE MODERN VIEWPOINT:-Every teacher of Psychology, whether or not he may favor the study of the subject from the objective standpoint, will read it with profound interest. From beginning to end a constructive attitude is maintained and, where possible, the material employed has been gathered by objective methods. No field, however, at present belonging to psychology, is neglected.

The text takes the position that psychology is a scientific study of human behavior, of the acts that man does through his original nature and hence apart from training, the acts which he can later do by reason of the putting on and retaining suitable habits. The importance of studying the individual in the light of his instructive equipment, the environment in which he has had to grow up, the system of habit which he has had to put on, and the stability of his emotional life are all emphasized.

The illustrations in the anatomical section have been prepared with great care and a number of the drawings were made under the direct supervision of Max Broedel.

BRIGHTNESS AND DULNESS IN CHILDREN

By HERBERT WOODROW, Ph.D.

Assistant Professor of Psychology in the University of Minnesota.

13 Illustrations. 322 Pages. $1.40 net.

The psychology of intelligence, the subject of which must form a large part of any thorough course in psychology, is not adequately treated in general texts. This volume covers the subject in a broad and systematic way and is a suitable textbook for courses in child psycholgy, mental diagnosis, mental development and education of children. It is of special value to teachers and school administrators, as it gives a thorough discussion of many of their fundamental problems. It gives the student an understanding of just how the most modern applications are made, in some very important instances, and a definite idea of the results achieved. The volume makes an excellent text for supplementing a course in general psychology or in any special branch where the scientific treatment of intelligence is regarded as important.

By MARY SCHENCK WOOLMAN, B.S.

Illustrated. 289 pages, including appendix, bibliography, glossary and index.

12mo. $2.00.

Clothing, next to food, is a most vital problem. Heretofore it has been a neglected subject either for study or reading.

It gives complete information on clothing materials, their properties, values, and prices. How to ascertain by sight as well as by feeling the difference between fibres; between poor and good cloths; how to identify them; how to test their value for buying; and a general knowledge of the growth, manufacture, dyeing, and finishing of textiles in general. There are also chapters on the care, repair, and renovation of clothing; dyeing, laundering, and spot removal. This book will help solve the great problem of securing clothing to please the eye, to stand the wear of daily use, and at a cost within reason.

JOURNAL OF OPTICAL SOCIETY OF AMERICA: "This book is sufficiently popular to interest anyone who reads simple English, and yet contains most of the essential scientific principles and technical data which are of importance to highly trained workers and students in this field.... It closes with chapters on the future developments in apparatus and methods, applications to technical and pictorial work and to exploration and mapping, all of which discloses the sound judgment and practical imagination of the author."

Invention Anticipates Necessity

The research laboratory of the General Electric Company at Schenectady is dedicated to the electrical industry.

Its facilities for scientific research, almost coextensive with the scope of electrical industry itself, surpass in variey and extent the equipment of university laboratories.

Scientific experimentation proceeds hand in hand with the development of new devices and new methods of manufacture. The result of this industrial research-the cooperation of science and industry-is first, the increase of scientific knowledge, and second, the embodiment of this increment in better materials and new devices which ultimately make happier and more livable the life of all mankind.

ABBE REFRACTOMETER, Bausch & Lomb, with heating prism, for the determination of refractive indices between no 1.3 and no 1.7 in fluid and plastic bodies, such as oils, fats, waxes, foodstuffs and colloids. The refractive index is read directly from the graduated circle, with an accuracy of from one to two units in the fourth decimal place. When used with white light, the dispersion is neutralized by the Abbe compensator, the mount of which is graduated, permitting measurements of mean dispersion. For this purpose a table of dispersion and conversion value is furnished with each instrument. We supply a hot-water heater and water pressure tank for use with this instrument when it is necessary to maintain a given temperature, but these are not included in the price below. 45778. Refractometer Abbe, as above described, with thermometer, test plate, 1⁄2 oz. monobromnaphthalene, and instructions for use, in case, with lock and key..$425.00 Price subject to change without notice.
