The fact is, that neither one nor other is the port, both, being considerably farther to the northward. Nay, more, the present town of Cosseir was no ancient port at all; old Cosseir was five or six miles to the northward. There can be no sort of doubt, that it was the Portus Albus, or the White Harbour; for we find the steep descent from Terfowey, and the marble mountains, called, to this day, the Accaba, which, in Arabic, signifies a steep ascent or descent, is placed here by Ptolemy with the same name, though in Greek that name has no signification. Again, Ptolemy places *[1] Aias Mons, or the mountain Aias, just over Cosseir, and this mountain, by the same name, is found there at this day. And, upon this mountain, and the one next it, (both over the port) are two very remarkable chalky cliffs; which, being conspicuous and seen far at sea, have given the name of the White Port, which Cosseir bore in all antiquity.
I found, by many meridian altitudes of the sun, taken at the castle, that Cosseir is in lat. 26° 7' 51" north; and, by three observations of Jupiter's satellites, I found its longitude to be 34° 4' 15" east of the meridian of Greenwich.
The caravan from Syene arrived at this time, escorted by four hundred Ababdé, all upon camels, each armed with two short javelins. The manner of their riding was very whimsical; they had two small saddles on each camel, and sat back to back, which might be, in their practice, convenient enough; but I am sure, that, if they had been to fight with us, every ball would have killed two of them, what their advantage would have been, I know not.
