This older book was put together in 1940 by William Howell and it is the 14th edition thoroughly revised. There is some underlining on pages with no dust jacket. It is over 1100 pages weighing around 5 ½ pounds. The previous 2 owner s names are on first front page. I actually like the look of this book just for the patina and character of book. This type of book looks great on bookshelves for display. But it also has some very interesting information about the human physiology.
