It is however presumed, that the Reader will not have found in perusal of this Journal, that there is much which may require his favour or excuse: yet some details appear to need explanation, and which (if a reference to the traveller himself were possible) might be given in a manner the most clear and satisfactory. In default of such advantage, the Editor offers an annotation or comment on two subjects of peculiar interest, treated of in this Journal, and in a manner apparently incorrect, or contradictory to accounts given by other writers. Page 15; the extent of the Oasis of Siwah, (as represented by Mr. Horneman) differs widely from that stated by every other writer ancient or modern. Page 23; the admeasurements of the sacred Egyptian building appear to vary in every proportion from those given by a late traveller of allowed accuracy, Mr. Brown. In the first instance, it is the purpose of the Annotator to ascertain the error, and to shew whence it has arisen. In the second case, he will have to place the subject in a point of view, by which an apparent variation in the two accounts may not only be reconciled, but even matter of new and just inference, as to the ancient construction and purpose of the building in question, be shewn to arise, from the very elucidation which corrects and compares these differences. Page 15; Mr. Horneman states “_the principal and fertile territory of Siwah to be fifty miles in circuit_:” in this he disagrees with every account given by the writers cited by Mr. Rennell, and with that latterly given by Mr. Brown, who, in conformity with the descriptions by other authors, states the extent of the Oasis, or fertile spot, to be six miles in length, and four miles and a half in breadth; not exceeding eighteen miles in circumference at the utmost. It will further appear that, in this respect, Horneman is not only at variance with the writings of others, but with his own, and that his own journal furnishes the strongest internal evidence in refutation of the fact he asserts.
