Note 26 — Chapter I
Reading edition
“No one who compares the maps of De Lisle and D’Anville with the materials then published, can doubt the excellent means of information with which they must have been supplied both by government, and by private individuals.” Murray.
We find a remarkable instance of De Lisle’s accuracy in Major Rennell’s construction of the geography of Mr. Horneman’s expedition. “Mr. Horneman was informed that there are 101 inhabited places in Fezzan.” It is remarkable that this is precisely the number stated in M. Delisle’s map of Africa, drawn in 1707; and, according to Mr. Beaufoy’s informant, there are nearly 100.
I have since found an older authority for the name Gambaroo, and which also shews that the name Quolla and its connection with the Gambaroo, have not been wholly unknown hitherto. It is in the L’Afrique de Marmol, livre viii. chap. 3. “C’est une chose estrange que ce fleuve venant de si loin, car Ptolomée le fait venir du lac Quélonide, et de celui de Nuba, il n’entraine pas tant d’eaux par ce costé-là, et la marée ne monte pas si avant, que par l’autre bras que l’on appelle Gamber.” One may almost fancy Quolla and Quellonide to have been derived from the Chalonides of Ptolemy.
