A naturalist and explorer, Francis de Castelnau undertook, between 1843 and 1847, a major expedition across South America, notably visiting Peru and Brazil.

In 1848, he was appointed French consul in Bahia. Upon his arrival, he observed that several African-born slaves could read and write Arabic and Libyco-Berber. Through interviews, some of them spoke to him about the Niams-Niams, or tailed men, said to live in a region referred to here as "Sudan", corresponding to present-day Nigeria. In this work, Castelnau presents the information he gathered on the subject. He describes several tribes from the Sudan region represented among the Bahia slaves: Nagos, Gèges or Dahomeys, Gallinhas, Minas, Borgos or Bargous, Tapas, Angols or Congos, Hausas, Fulanis or Foullatahs. He then recounts the interrogations of Bahia slaves who claimed to have seen or heard of the Niams-Niams, thereby collecting a wealth of ethnographic and geographic information on that part of Africa. The volume ends with a vocabulary section in several Sudanese languages (Hausa, Fulani, Courami, Java).

A handsome and scarce copy.
