APPENDIX.

It is obvious, that as neither St. Louis nor Jillifrey, are exactly deter- 
mined, in respect of Cape Verd, or of each other, it would be idle to 
attempt a critical adjustment of them ; and therefore I have adopted the 
position arising from Mr. Park's route, corrected by 24 miles, or 25 min. of 
longitude, more to the west; so that Fort St. Joseph stands in the map in 
Ion, 9^ 46', lat. 14° 34'. 
In consequence of this correction, all the eastern positions, Joag, Jarra, 
Sego, &c. must of course recede 25 minutes to the westward of the arrange- 
ment heretofore made, on the construction of Mr. Park's geographical 
materials. Hence I place 
Joag, in 9° 37' west, instead of 9° 12' 
Jarra, in 7 13 6 48 
Sego, in 2 26 ■■ 2 1 
Silla, in 1 24 ^ 59 
And Tombuctoo, in 1 33 east, ■■ 1 58* 
I now proceed to state the reports of the distance to Tombuctoo, from 
the NW, N, and NE. 
From Tatta t on the southern frontier of Morocco, q\ journies to the 
SSE of the capital, (equal to 157 G. miles} the distance is 50 journies of 
he caravan, according to Mr. Matra. 
From Mourzouk, the capital of Fezzan, (taken to be in latitude 27° 48' 
and longitude 1 5° 3' east, or directly south of Mesurata), 64 journies, accord- 
ing to the report of Ben Ali. And from Tunis, 77 journies, through 
Kabes and Gadamis, according to Mr. Magrah. 
On the route between Mourzouk and Cairo, as well as between Morocco 
and Jarra, it has been already stated (p. xxxviii), that 16,3 and 16,25 ^^'"^ 
the mean rates : and the former was accordingly adopted between Woolli 
and Sego. At the same rate, the 50 days from Tatta, give 815 G. miles, and 
the 59!^ from Morocco, 970. The 64 from Mourzouk give 1043 > 
die 77 from Tunis, 1255. 
• The latitudes remain as they were.
