378 Scientific Intelligence. 



The questions sent to the contributors invited opinion on the 

 coming of the new ' ' psyche, ' ' ; its influence, material or spir- 

 itual ; its trial by experts ; and its utilization. The papers are 

 grouped in two parts, the first treating of religion, philosophical 

 and theoretical; then practical. The second part deals with 

 science. Dr. Grenf ell, in his brief note on ' ' the moral sanction, ' ' 

 well says that the subject should be handled ''with open mind, 

 with great caution, and rock bottom common sense." 



3. Types of Mental Deficiency; by Martin W. Bare, M.D., 

 and E. F. Maloney, A.B. Pp. 179. Philadelphia, 1921 (P. 

 Blakiston's Son and Company). — The leading author of this 

 book some years ago wrote a standard treatise on Mental Defec- 

 tives. He has had such extensive experience in the subject as 

 chief physician of the Pennsylvania Training School for Fee- 

 bleminded Children at Elwyn, Penna., that any work of his 

 merits careful consideration. 



The present volume is in the nature of a clinical album, con- 

 taining as it does 188 half-tone illustrations of all types of defec- 

 tives ranging from the lowest grade idiots to dementia praecox 

 patients. These half tones are moderately clear. The accom- 

 panying descriptions are very informal, often containing facts 

 which have no particular clinical significance. The very infor- 

 mality and unpretentiousness of the treatment, however, impart 

 to the book a readable quality. We know of no more convenient 

 way in which the general reader could 'visit' an institution and 

 see all of the most interest and significant cases with running 

 comments b}^ the superintendent. Dr. Barr follows his old edu- 

 cational classification of mental defectives. He refuses to adopt 

 the term Moron but employs instead the term "backward" and 

 nowhere does he mention the name of Alfred Binet. No mental 

 measurements of the cases are reported. The references to their 

 vocational capacity, however, are interesting and suggestive.

4. Practical Bank Operation; prepared by L. H. Langston. 

 In two volumes : vol. I, pp. xxv, 370 ; vol. II, pp. 373-713. New 

 York, 1921 (The Donald Press Company; price $8). — Practical 

 Bank Operation has been admirably prepared by Mr. Langston 

 under the direction of the Educational Committee of the National 

 City Bank and is unique in this respect, that, while all ordinary 

 functions of banks in general are stated and then in detail, 

 described, there is nothing theoretical about it. Every operation 

 described is taken, so to speak, from real life. It is the way 

 that particular operation is handled today by one particular 

 bank, a bank in many ways representative of the best in banking 

 practice, for magnitude of business done, variety of services 

 rendered, and efficiency in performance. The purpose of the 

 book in fact is to show how a particular institution performs the 

 functions enumerated. This institution being the largest of its 

 kind, of necessity, has a highly organized department for prac- 

 tically every banking function, so that the small provincial bank
