GEOGRAPHICAL 
Tombu£lou, at thirteen each day, produces fix hundred and fifty 
miles. By JBen AlU's report, Tombudou is forty-eight days from 
the capital of Sultan Fullan, lying witliin the diftrid of Gallam^ 
on the River Senegal. The pofition of this place is not known

in latitude 19^.40^ and nearly midway between Gallam and 
Cafhna. In this pofition, it falls only twenty-eight miles to 
the North Weft of D'Anville's Tombudou.

Zahara, or properly, The Desart. Geography is atprefent, 
very bare of particulars, in this quarter. Ben AlH went from 
Tombu6:ou, direft to Fezzan, {kirtiiig the South Eaft border of 
this great Defart. He reckoned only fixty-four days between 
Tombu(9:ou and Fezzan, which at twelve miles and half per 
day, produce only eight hundred miles. The interval on the 
Map is nine hundred and feventy. Reafon, however, points 
out, that the diftance from the neareft place, Gallam, ought to 
fee preferred. And as it is underftood, that Agadez and Tom-
