Brain And Mind Or The Nervous System of Man. By R. J. A. Berry, M.D., F.R.C.S., F.R.S. Published by  The Macmillan Co., New York. Pp.  558 + References, Appendix and Index.

This book is in the main an excellent presentation of the anatomy of the central nervous system by a skilled anatomist. The structure of this most important of tissues is set forth very fully and very satisfactorily and illustrated by a sufficiency of photographs, drawings and diagrams.

Finally, in the last few chapters the author discusses more particularly the brain as the physical instrument of the mind, certain mental phenomena such as sleep and dreams and the emotions, and then goes on to a discussion of the various forms of mental disorder. This is by all means on the whole the least satisfactory part of the book. In his general thesis he is committed to an explanation of mental phenomena in neurological terms, which means that in very many instances he merely translates one set of terms into the other without adding at all to the clarity of the situation. It is another example of “neurologizing tautology.” However, the reviewer has every sympathy with his efforts to correlate structure and function but believes that while these two concepts will always continue to grow closer and closer together that they will never quite fuse. The author seems to be very much disturbed by the people who deprecate the mixing of ideas and brain cells and is insistent that it is just this attitude of mind which interferes with progress. He has very interestingly reanimated the very important work of Bolton upon the cerebral cortex and has much to say on this subject in relation to mental disease that is interesting. His scheme for the examination and diagnosis of mental states is again an exceedingly interesting scheme for sifting out certain more or less obvious types but the reviewer questions whether it would stand the test of a great number of cases that are more difficult of diagnosis because the patients seem to be at least more normally equipped. And finally the reviewer thinks that it is exceedingly unfortunate that the author should take occasion frequently to speak so
