probable that the interval between Fezzan and Tombu£tou,

The point of the next importance, is Bornou, the capital of 
an extenfive kingdom fituated on the South Eaft of Fezzan, and 
between the two Neels or Niles ; that of Egypt, and that of 
the Negros, 
• Bornou, is given by the Shereef, at about fifty days from 
Mourzouk (or Fezzan) which may be taken at fix hundred and 
fifty miles. He alfo reports that it is twenty-five days journey 
from the courfe of the Nile, where it paffes the country of Sen- 
nar ; or in diftance about three hundred and fixty miles. This 
would place Bornou in a dire6tion of South Eaft, fomewhat

Matthan^ a city of Kanem^ lies thirty-one days from Nuahia (on 
the Nile) through Tegua, Geog. Nub. p. 15. Edrifi's day's 
journey is equal to eighteen Arabic miles, or nearly nineteen
