According to the author Auguste Forel, the book "Ants and Some Other Insects" presents an inquiry into the psychic powers of these living creatures and contains an appendix on the peculiarities of their olfactory sense.

This book looks at the family, marriage, sex, and gender. It was first published in the early 1920s when many people, especially young girls, were not at liberty to discuss matters of a sexual nature. This book seeks to educate, explain and discuss morality concerned with sexual matters.
