1911 Encyclopædia Britannica/Ibo

IBO, a district of British West Africa, on the lower Niger immediately above the delta, and mainly on the eastern bank of the river. The chief town, frequently called by the same name (more correctly Abo or Áboh), lies on a creek which falls into the main stream about 150 m. from its mouth and contains from 6000 to 8000 inhabitants. The Ibo are a strong well-built Negro race. Their women are distinguished by their embonpoint. The language of the Ibo is one of the most widely spoken on the lower Niger. The Rev. J. F. Schön began its reduction in 1841, and in 1861 he published a grammar (Oku Ibo Grammatical Elements, London, Church Miss. Soc.). (See Nigeria.)
