Anatomy of the Human Body by Henry Gray
From Embryology
Introduction
Classic anatomy textbook widely reproduced online, particularly the anatomical illustrations, due to the fact that the 1918 edition is out of copyright. W.H. Lewis edited the 20th edition published in September 1918, the current 40th edition was published in 2008. The majority of images were anatomical drawings with some cartoon simplifications. The text also includes earlier historic drawings, particularly in the embryology section that commences the text.
