Baillière, 1843. 2 vols. in-8, green half-chagrin, spines with decorated faux-nerves, spotted tr. (period binding). Illustrations in black in the text, and 39 lithographed plates outside the text numbered I-XL (XXXIX and XL placed on the same sheet), including 5 in black and 34 colored and gummed. Freckles, stain on the first leaves of volume 1. A good copy. First French translation of Natural history of man (1843). Its iconography is richer than the original, which only includes 26 colored plates. A physician who specialized early in the field of psychiatry, James Cowles Prichard (1786-1848) was also very interested in the young discipline of anthropology which was then in its infancy. He supported from the beginning the fundamental unity of the human race, which was still under discussion at the time.
