state of the atmosphere. The learned will, no doubt, 
deeply regret that he was unprovided with instruments 
for observing and measuring meteorological phenomena : 
but it is not on a man's first travels that these lights 
can be obtained ; and, besides, none of our readers have 
forgotten the perils which attended our countryman in 
the execution of his enterprize. 
The situations of several known places experience ex- 
traordinary changes in consequence of M, Caillie's pere- 
grinations, without mentioning the towns washed by the 
Dhioliba. Toudeyni, which was supposed to be 3 J de- 
grees west of the meridian of Timbuctoo, proves by M. 
Caillie's route to be very near the wells of Telig, only 
4(y west of that meridian. Is this another place of the 
same name ? I doubt it : its importance, proved by the 
description given of it b}^ our traveller, repels the suppo- 
sition. A'raouan^ is inscribed in the maps as a mere 
station, with a well of brackish water; but M. Caillie 
found this a considerable place, a commercial entrepot, 
in a word, an important town, notwithstanding the par- 
tial decay of its prosperity. 
M. Caillie makes us acquainted in the north with 
miration it produced, and the advantage he derived from that admira- 
tion. This narrative sheyvs, that this is one of the portable articles 
which Europeans would be most certain of exporting with success to 
Africa.
