atchieve, appears on the Map to be feven hundred andfeventy 
miles; being equal to fourteen and half for each day: and is on 
the whole, feventy more than I fhould have expeQ:ed that num- 
ber of days to produce. To what degree of accuracy the dif- 
ference of longitude between Mefurata and Cairo, is afcertained, 
I am ignorant: as alfo whether the bearing of Mourzouk from 
Mefurata, be right. Fourteen miles and half of horizontal dif- 
tance for each day, on fo long a line of diilance, and on fo rugged 
a way as the Itinerary defcribes, is too great a proportion ; and 
we may fulped an error fomewhere, ; . , • c ; ; \ 
A circumftance occurs in the Itinerar}", which would deter- 
mine how near this route approaches to the Coaft of the Medi- 
terranean Sea ; if we might depend on the accuracy of the Itine- 
rift. The dates produced in the Plain of Gegah lb ^ ^ixc gathered 
by the people of Duna, who inhabit the fea coaft, eight days 
journey off ; or about one hundred and thirty miles. No fuch 
place as Duna appears in the modern maps ; but Derna (anti- 
ently Darnis) does: and it is fituated within the confines of 
Tripoli, as Duna is faid to be. But the diftance muft be faulty ; 
becaufe Augela is the neareft point in this route, to Derna, 
though ten days from it : and Gegahib, is feven days from Au- 
gela, in a diredion that ftill increafes the diftance. --^
