Note 5 — Chapter XIV

"The large river Tumbiri, mentioned by Dr. Krapf as flowing towards Egypt from the northern counterslope of Mount Kenia, rests upon the sole authority of a single wandering native. As, moreover, the word T'humbiri or Thumbili means a monkey, and the people are peculiarly fond of satire in a small way, it is not improbable that the very name had no foundation of fact. This is mentioned, as some geographers—for instance, Mr. Macqueen ('Observations on the Geography of Central Africa,' Proceedings of the R.G.S. of London, May 9, 1859)—have been struck by the circumstance that the Austrian missionaries and Mr. Werne ('Expedition to discover the Source of the White Nile, in 1840-41') gave Tubirih as the Bari name of the White Nile at the southern limit of their exploration."
