Note 10 — XXXIII
Reading edition
The Esere or Calabar bean is a strong poison, and was formerly much used by the natives. These beans are ground up in a stone mortar, and are then swallowed by the accused person. If the man dies he is considered guilty, but if he lives, he is supposed to have proved his innocence of whatever the charge may have been which was brought against him. Death generally ensues about two hours after the poison is administered. If the accused takes a sufficient amount of the ground-up beans to make him vomit it will probably save his life, otherwise he will die in great pain.
