Decas collectionis suae craniorum diversarum gentium illustrata. 6 parts plus supplement.

Blumenbach was the founder of craniology, and his craniological collection served as the principal foundation for his investigations into the natural history of mankind. He used the norma verticalis, the shape of the skull as seen from above, as the means of distinguishing three types: Mongols, Negroes, and Caucasians. The above work includes a description of the uncinate (“Blumenbach’s”) process. See No. 156.
