Mr. Horneman’s Journal of his Travels from Cairo to Fezzan commences five days after the date of this letter. It was by him written in German, and in that language transmitted to the Committee of the African Society. Under their direction, a translation of it was made by a native of Germany, sufficiently versed in the English language, to render the sense of the original with truth and perspicuity; and, on collating his version, it appears to have been executed with fidelity and care. Some correction of foreign idioms and style was yet required: the Secretary, in performing this duty of Editor, has been attentive to the preserving not only the genuine descriptions, remarks, and precise meaning of the traveller, but likewise the spirit, and (at the same time) simplicity of narrative which characterizes his Journal; and, it is presumed, that on reference to the original, the translation offered in its present form will _yet_ appear to be as nearly literal, as the different idioms and context of the English and German languages will admit of. To the Journal now printed is added an Appendix, containing, 1st. A Note, on Mr. Horneman’s Description of the Country and Antiquities of Siwah; with Reference to ancient Accounts of the Oasis and Temple of Ammon; by the Secretary, Sir William Young, Bart. F. R. S. 2d. A Memoir, containing various informations respecting the interior of Africa, transmitted from Mourzouk, in 1799, by F. Horneman. 3d. Geographical Elucidations of the Travels and of the Informations of F. Horneman, with Maps, by Major James Rennell, F. R. S. 4th. Remarks on the Language of Siwah, in a Letter to the Right Hon. Sir Joseph Banks, P. R. S. by William Marsden, Esq. F. R. S. [Illustration: _The ROUTE of_ MR.
