The position of New and of Old Cairo is well known, and has been often described. Two writers, who were intimately acquainted with ancient and modern Egypt, have fixed, after a learned inquiry, the city of Memphis at Gizeh, directly opposite the Old Cairo, (Sicard, Nouveaux Memoires des Missions du Levant, tom. vi. p. 5, 6. Shaw's Observations and Travels, p. 296 - 304.) Yet we may not disregard the authority or the arguments of Pocock, (vol. i. p. 25 - 41,) Niebuhr, (Voyage, tom. i. p. 77 - 106,) and above all, of D'Anville, (Description de l'Egypte, p. 111, 112, 130 - 149,) who have removed Memphis towards the village of Mohannah, some miles farther to the south. In their heat, the disputants have forgot that the ample space of a metropolis covers and annihilates the far greater part of the controversy.
