Peru

He wrote a textbook on Peru called ''Peruvian antiquities'' in which he recorded various aspects of Peruvian life and history. In his book he explained the various skull angles of Peruvians in the context of the Angle of Camper. Tschudi claimed that Camper's facial angles were an "important angle in anthropology", whose "greater or less opening indicates the intellectual superiority of a race, and, up to a certain point, of individuals". He went on to explain that he had obtained for his personal collection the mummified foetus of a woman at seven months found in the cave of " Huichay" ("two leagues from
