The number of editions which this book has gone through in the last thirty years tells the story of its usefulness and popularity. This edition, the ninth, is revised by Dr. Clark in place of the late Professor Ranson. The book deals systematically with the anatomy of the central nervous system and does not lend itself to a detailed review. However, as a convenient reference work it seems to us highly adequate. There are many excellent illustrations; the paper and print are good. There is a bibliography and an index.
