ABNORMAL PSYCHOLOGY. 



We take this opportunity to announce to our readers the appear- 

 ance of two noteworthy contributions to the Hterature of Abnormal 

 Psychology, namely, Jastrow's ^ discussion of the subconscious 

 and Prince's^ book on the dissociation of personality, as well as 

 of a new journal devoted to the materials of one division of Com- 

 parative Psychology, The Journal of Abnormal Psychology.^

 sembled a large number of observations concerning normal and 

 abnormal subconscious states. The author's discussion of the 

 facts of subconsciousness makes clear their importance in life and 

 suggests many problems concerning the genesis of subconscious- 

 ness and its relations to consciousness. Aside from its value as 

 a source of materials, this book is important because it shows that 

 the subconscious is always with us, as much a part of our mental 

 life as is consciousness proper and scarcely more likely to be ab- 

 normal or morbid. There is no reason for regarding it as mys- 

 terious; there is every reason for the recognition of its fundamental 

 importance for life. 



Dr. Prince's book is the result of prolonged observation and 

 experimental study of a case of multiple personality, which, as 

 the author remarks, has proved to- be a mine of psychological 

 material. Miss Beauchamp, the individual in question, exhib-

 personalities, certain phenomena of amnesia, aboulia, impulsion, 

 automatism and subconscious activity which are of great inter- 

 est to both neurologists and psychologists. The patient, natur-
