Travellers in.  Egypt and Nubia have been numerous since the time of Mr. Burckhardt; but as they chiefly directed their investigations and inquiries to the antiquities of the country, they do not come within our proper notice; we shall therefore merely mention the names of Belzoni, (whose antiquarian discoveries have been so numerous and splendid,) Mr. Salt, Mr. Bankes, &c.  To this latter gentleman, however, geography is also indebted for important additions to its limits; or, rather, for having illustrated ancient geography.  He penetrated, as we have already mentioned, as far as the second cataract:  he visited some of the most celebrated scenes in Arabia, and made an excursion to Waadi Mooza, or the Valley of Moses.  He also visited Carrac; but the most important discovery of this gentleman relates to the site of the ancient Petraea, which was also visited by Burckhardt.  Onr readers will recollect that this city has been particularly noticed in our digression on the early commerce of the Arabians, as the common centre for the caravans in all ages; and that we traced its ancient history as far down as there were any notices of it.  Its ruins Mr. Bankes discovered in those of Waadi Mooza, a village in the valley of the same name.

Since Mr. Burckhardt travelled, geographical discoveries have been made in this part of the world by Messrs. Ritchie and Lyon, Lord Belmore and Dr. Richardson, Messrs. Waddington and Hanbury, Messrs. Caillaud and Drovetti, Sir Archibald Edmonstone, Sir Frederick Henniker, and by an American of the name of English.  The travels of Messrs. Ritchie and Lyon were confined to Fezzan, and are chiefly curious for the notices they give, derived from native merchants, of the course of the Niger, By means of the travels of Lord Belmore and Dr. Richardson, the latitudes and longitudes on the Nile have been corrected from Assouan to the confines of Dongola.  Mr. Waddington and Mr. Hanbury, taking advantage of an expedition sent into Ethiopia by the pacha of Egypt, examined this river four hundred miles beyond the place to which Burckhardt advanced.  The travels of the two French gentlemen extended to the Oasis of Thebes and Dakel, and the deserts situated to the east and west of the Thebaid.  In the Thebaic Oasis some very interesting remains of antiquity were discovered:  the great Oasis was well known to the ancients; but the Thebaic Oasis has seldom been visited in modern times.  Brown and Poncet passed through its longest extent, but did not see the ruins observed by Mr. Caillaud.

This gentleman, who was employed by the pacha to search for gold, silver, and precious stones, after a residence of five months at Sennaar, traversed the province of Fazocle, and followed the Arrek, till it entered the kingdom of Bertot.  At a place called Singue, in the kingdom of Dar-foke, which is the southern boundary of Bertot, situated on the tenth parallel of latitude, and five days’ journey to the westward of the confines of Abyssinia, the conquests of Ishmaei Pacha terminated.  Only short notices of these travels of Mr. Caillaud have as yet been published.
