[60] It is the same with that from Djenné to Timbuctoo.
[61] M. Walckenaer, as I have elsewhere said, was among the first to acknowledge the necessity of this alteration. See Recherches, &c. See also Vol. II, of the Mémoires de la Société de Géographie, and its Bulletin or Recueil périodique.
[62] The journal shows four days’ distance; these must be days of twelve leagues: there are actually eight ordinary days’ journeys with the windings.

[67] In the map which accompanies his work, M. Walckenaer places Tafilet about 5° east of Morocco; but M. Lapie, in the map to M. Cochelet’s travels makes it only 3 degrees and a half distant. This is also the difference of longitude which results from the route of M. Caillié as traced by me, the positions of Morocco and Fez being moreover precisly known. The whole eastern part however of the empire of Morocco presents difficulties and uncertainties, which cause the necessity of new observations to be sensibly felt.
[68] May not the too great remoteness of Tafilet from Fez arise from the custom of which I have spoken, which always exaggerates itinerary distances?
