2. The _Mons Ater_ of Pliny, recognised in the _Black Harutsch_. 3. The site of Memphis, before involved in doubt and obscurity. 4. The singular conformation of the Mound of _Bubastis_, in Lower Egypt, proved by the French _Sçavans_.[81] Although a part, only, of these discoveries, have been made by persons employed by the Association, yet it is probable that the gentleman to whom we owe some of the most brilliant of them, was in part determined to the pursuit, by the discussions set on foot by the Association; which had been established some years before Mr. Browne’s travels commenced. POSTSCRIPT. When the above Memoir was printed, I was ignorant that the following passage occurred, in Mr. Horneman’s Letter of the 6th April, from Mourzouk. “I spoke to a man who had seen Mr. Browne in Darfoor: he gave me some information respecting the countries he travelled through, and told me, that the communication of the Niger with the Nile, was not to be doubted, but that this communication before the rainy season, was very little; in those parts, the Niger being at the dry period _reposing_, or _non fluens_.” If the authority is to be depended on, it proves two facts: first, that the _Niger_ and _Nile_, (that is the _western_ branch, or _White_ River), are by no means one and the same river; but, on the contrary, that their fountains are perfectly distinct: for, it is agreed on all hands, that the White River is a very large stream, at all seasons; whereas, we are here told that the Niger discharges into the Nile, during the dry season, only a very small portion of its waters: consequently, the waters of the Nile must come from some other quarter than the Niger. The other fact is, that during the dry season, the waters of the Niger are generally evaporated in the inland country: a fact disbelieved by many, from their not being well informed respecting the powers of evaporation. The communication above alluded to, may probably turn out to be that, between the lakes of Wangara and Fittré; which is described by Edrisi as a part of the track of the salt trade along the Niger. It may be proper to repeat, that the _Misselâd_ of the map, answers to the upper part of Edrisi’s _Niger_. ERRATA IN THE GEOGRAPHICAL MEMOIR.
