The author Ferdinand Karsch (who died on December 20, 1936, in Berlin) was a German entomologist and sexologist. In this volume, he describes the same-sex lives of indigenous peoples. In addition to discussing fundamental concepts such as love, homosexuality, and sexual life, he presents pederasty among Australians, Melanesians, Africans, Malays, Polynesians, Micronesians, Mongolians, Eskimos, and American indigenous peoples. In the second part, he addresses the position of women and describes Amazonism, the Hottentot apron, and more. Illustrated with seven images in the text and seven full-page illustrations.
