sea, because it runs obliquely between them. The distance appears to be 
no greater than 72 miles on an ENE course, from Ghinna to the nearest 
part of the coast. 
Cairo, by the mean of several accounts, is about 59 G. miles to the 
west of Suez, equal to i° 8' of longitude. t So that Cairo should stand in 
the Nile, at five hours above Ghinna. The camel's rate is z\ British miles by the road : 
consequently less than two G. miles in direct distance. 
M. Savary had much the same idea of the distance; for he reckons it 33 French 
leagues. (Vol. ii. letter 2.) But his Map has 70 G. miles only: Pocock's 90. 
Mr. Irwin reckons the bearing WNW from Kosire to Ghinna ; doubtless by compass. 
The variation might be 13 to 14 degrees; whence Ghinna would bear W 9 0 N from 
Kosire : Banute, which is stated to be about five hours to the south of Ghinna, will there- 
fore by this account bear N of W from Kosire. Mr. Irwin was certainly very near 
the mark ; though a little too much northerly. It appears that Banute is in lat. 
2 S° 47' 3°" m D'Anville, and is 8 min. N of Negada; at which place, Mr. Bruce observed 
the latitude to be 25 0 53' 30". Consequently D'Anville is 14 min. too far south in this 
part. Apply this to Banute, and we have 26 0 1' 30". Kosire lies in 26 0 8', and Banute is 
then to the south of it, in reality, by several minutes. At Syene, Mr. Bruce's latitude is 
1 1 min. north of D' Anville's. Not to go into extremes, I have taken Banute at 5 min. S 
of Kosire, Ghinna 3 min. N of it ; or 26 0 11'. D'Anville places Ghinna in 26 0 1'. It 
was of importance that these parallels of the places should be adjusted. 
f The principal authorities are the following : 
M. Niebuhr reckoned between Suez and the Lake of the Pilgrims, situated at 6,9 G. 
miles E 38 N from Cairo, - 28 h 40™ 
M. Volney, - - - - 29 — 
Dr. Pocock, - - - - - 29 15 
mean 28 58 
Add from the Lake to Cairo, as it is usually reckoned, - 3 — 
or say 32 hours 31 58 
But as there are (besides the just mentioned 3 hours, in a direction of about 40 0 from the 
general line of direction) 3! hours more between Suez and Ajerud, at much the same 
angle, a considerable reduction of the direct distance must take place, probably about \\ 
hour : whence there remains y>\. And as Dr. Shaw states the general report of the 
distance to be 30 hours, it may be conceived that this is the actual distance, by the 
shortest route, which leaves the Lake and Ajerud to the north. And for these, 59 G. 
miles direct may be allowed. M. D'Anville allowed 60.
