the situation of Bour^ ; we were ignorant whether there 
existed a town of this name, and even what was the site 
of the country of Boure : in the maps we shall find dif- 
ferences of several degrees. M. Cailli^ did not visit 
Bourd ; but, in throwing together all the particulars which 
he collected, I find sufficient data to determine the situa-

three quarters of a day's journey from the latter in a 
direct line, or one day's above the confluence. These 
particulars which agree well together, were furnished by 
various persons in various places. Moreover the position 
of Boure is given by its distance from Kankan ; and its 
bearing, namely, four or five days to the north, J N. E., 
in descending Milo. Finally, as a fourth testimony, we 
learn that Boure was five days' march from Couroussa, 
descending the Dhioliba in a canoe, and afterwards as-

Bamakou is known to us from the second journey 
of Mungo Park ; but its actual situation should be con- 
siderably further to the west : the information ob- 
tained by M. Caillie, and the construction of the map, 
place this town at about the tenth degree of longitude 
west of Paris, and in latitude eleven degrees forty -five 
minutes. The idea of forming an establishment there, is 
founded upon a real knowledge of the country ; it was
