Note 1 — PREFACE.

If the reader should wish to consult Dr. Perron’s work in the British Museum, he will find the “Voyage au Darfour” under the head “Muhammad Ibn Umar,” in the Old Catalogue, p. 98 b; and the “Voyage au Wadaï” under the same head in the New Catalogue. I believe that, after “Mehemet,” it would be impossible to select a system of spelling more likely to mislead in pronunciation. The Arabic version will be found in the New Catalogue—also under Muhammad, but further on, p. 103 a.
