In the 33 years since the first edition was published, this book has gained a secure place among textbooks on anatomy. After the senior author's death, a partial revision for the eighth edition was carried out by Dr. Clark in 1947. He has now made further and more extensive changes, adding material on the significant advances of recent years, new illustrations, and rewriting completely many portions of the text. The present edition is, therefore, practically a new publication. Few authors have taken so much care in the revision of a standard work as Dr. Clark has; his efforts have paid rich dividends. Arrangement, style, format, and illustrations are excellent. Previous editions become obsolete when such full and pains-taking revision is accomplished.
