Note 133 — Chapter II

Heeren (Trade of the African Nations, vol. i. p. 182) supposes that in Africa, dates are comparatively little known south of 26° north lat. But this learned writer is certainly mistaken; and a reference to the following passages will show that they are common as far down as the parallel of Lake Tchad, which is nearly the southern limit of our knowledge of Central Africa; Denham's Central Africa, p. 295; Clapperton's Journal, in Appendix to Denham, pp. 34, 59; Clapperton's Second Expedition, p. 159. Further east they are somewhat scarcer, but are found much more to the south than is supposed by Heeren: see Pallme's Kordofan, p. 220.
