Introduced the theory of localization of cerebral function, although in a somewhat fantastic form. This pioneer attempt to map out the cerebral cortex according to function gave rise to the pseudo-science of phrenology. The work also contains some important additions to the knowledge of cerebral anatomy. Gall and Spurzheim ended their collaboration after the first 146pp. of Vol. 2. The remainder was written by Gall alone. The first edition was issued in two formats: (1) text and atlas all in folio and (2) text in quarto and atlas in folio. The second edition was revised by Gall, and published without the plates, but with a collection of replies to his critics as Sur les fonctions du cerveau et sur celles de chacune de ses parties. 6 vols., 8vo, Paris, l’Auteur, 1822-25. English translation of second edition, 6 vols., Boston, 1835.

Choris was the artist aboard the Rurik, 1815-18, commanded by Otto von Kotzebue. After visiting islands in the South Seas, Kotzebue explored the North American coast and landed twice in the Hawaiian Islands. Choris's work, illustrated with 104 plates, is of particular interest for the outstanding images, and includes scientific information by Cuvier, Chamisso, and Gall. The book was issued in 22 parts. Buyers had the option of ordering the plates in black & white, the plates partially colored and partially uncolored, or with the plates entirely colored.
