Firstly, Mr Wakefield, like Doctors Livingstone and Kirk, all being practical linguists, invariably uses the system of Zangian orthography, adopted by the ‘Mombas Mission,’ and by myself since 1859. He speaks, for instance, of Kilima-njaro and Unyamwezi, not the Monomoezi of Mr Cooley or ‘the authentic word Mueni Muezi,’ translated landlord, or petty chief country (p. 11, The Memoir on the Lake Regions of East Africa reviewed, &c. &c., by W. D. Cooley. London: Stanford, 1864). We find in Mr Wakefield’s Notes (p. 316) ‘_Líma_, a term denoting extraordinary size—Mlíma being the general term for mountain,’ whilst (p. 321) Ki-Mrima is justly applied to the dialect spoken on the Mrima or mainland facing Zanzibar Island. We read also (323) ‘Mtanganyíko,[126] Kisawáhílí, meaning the place of _mingling_ or _mixture_ (rendezvous).’ This is precisely the meaning attached by me to the Lake’s name, yet I was assured in the Memoir above alluded to (p. 7) that nothing can be ‘more ridiculous’ than my explanation of Tanganyika. Even in philological details of the Kisawahili dialect Mr Wakefield agrees with me. He writes, for instance, Udogo (Notes, p. 313), Ugala (Footprints, p. 67, 68), and Ulangulo (Ibid. p. 63). I was assured in the Memoir (p. 9) that U is prefixed to the names of countries only by Dr Krapf and Captain Burton—this, too, after I had for years been talking of Europe as Uzungu, literally, Land of white men. Mr Wakefield speaks of Wasămbá, of Wasawahili (or Wa-Sawahili), and of Wanyamwezi, thus sanctioning the use of Wamrima, continental men, and Wakilima, hill-men. He adopts Kisawahili, Kikwavi, Kimasai, and so forth, prefixing an adjectival particle ‘Ki’ to the root, and denoting chiefly dialect, yet I was assured by Mr Cooley (Memoir, p. 9) that ‘Ki’ has never an adjectival form. I may now invite the author of Inner Africa Laid Open to revise the verdict (Memoir, p. 7) which pronounces me ‘totally ignorant’ of the language of which I affect to be master. It may be deemed trivial to dwell upon these philological minutiæ, but, firstly, nothing is unimportant when it affects the accuracy of a traveller, especially of an explorer, in the smallest matters of detail. Secondly, without an exact nomenclature all topographical literature must be imperfect and of scant value. And, finally, as Mr Cooley and I have been differing upon these points for the last ten years, it is well that the portion of the public which takes an interest in the subject should see who is right and who is not. I have no personal feeling in the matter; and if the ‘Geographer of N’yassi’ will bring, as I have done, independent testimony to bear upon the points in question, and not evolve his learning out of the depths of his self-consciousness, I am at all times ready and willing to own myself wrong.
