THE PSYCHOLOGY OF INSANITY 
By BERNARD HART, M.D. (Lond.), Lecturer in Psychiatry, University 
College Hospital Medical School; Medical Superintendent, North¬ 
umberland House Asylum. 
Cambridge Manuals Series. Cloth, Is. net ; leather 2s. 6d. net. 
“In this little work ...the author has briefly presented In lucid readable form the more important recent 
developments in abnormal psychology which have yielded results of fundamental importance or which have acquired 
a satisfactory claim to recognition. In this book the author, after briefly reviewing the history of insanity, goes on 
to explain what is meant by the psychological conception, and then arranges the subject-matter of the book in such 
a way that the three successive steps of the method of science appear in logical order.An earnest attempt has 
been made to lay the essential features of this interesting section of science concisely before the reader, and an 
excellent groundwork has been prepared upon which to build a more extensive knowledge of the subject.”—
