Excerpt from Elements of Physiological Psychology: A Treatise of the Activities and Nature of the Mind From the Physical and Experimental Points of View (Thoroughly Revised and Re-Written) I am under particular obligations to Dr. James K. Thacher, Professor of Physiology in the Yale Medical School, for valuable assistance in that description of the Nervous Mechanism, its struct ure and functions, which the First Part of the book contains. If I have escaped the mistake of assuming to teach more than is really known upon this subject, it has been in large measure due to his friendly and skilful guidance. Valuable assistance has also been received from Russell H. Chittenden, Professor of Physiological Chemistry, and Charles S. Hastings, Professor Of Physics - both of the Sheffield Scientific School. The method and arrangement of the book have been chosen so as to fit it for use, both as a text-book by special students Of the subjects Of which it treats, and also by the general reader who is interested in knowing what results have been reached by the more modern - and even the latest - psycho-physical researches.
