Originally published in 1907, this early work on the human race is both expensive and hard to find in its first edition. It contains details on human growth, heredity and health using the analogy of plants. This is a fascinating work and thoroughly recommended for anyone interested in the way the human race used to be perceived. Many of the earliest books, particularly those dating back to the 1900s and before, are now extremely scarce. We are republishing these classic works in affordable, high quality, modern editions, using the original text and artwork.
