of approximating the position. But, notwithstanding, it will appear, that 
on the whole, it coincides most wonderfully with the other data. 
The bearing in question, pointed out at different times, was commonly 
E by S, by compass : and Mr. Park never found his informant vary more 
than half a point, which was to the southward; or E by S 4- S.' But the 
idea left on his mind, was E by S ; which, allowing 17 degrees variation, 
is about east half north ; or more correctly, E 5^: N. And hence, ad- 
mitting the distance of 200 G. miles between Silla and Tombuctoo, which 
supposes a space of about 500 such miles between Benowm and Tombuctoo, 
this latter would fall at about 50 minutes of latitude northward from Be- 
nowm (whose parallel is the same with that of Jarra, 15° 5'), and conse- 
quendy in 15° 55'. The obliquity of the intermediate meridians, might 
increase the parallel some minutes, and we may call it roundly 16°. 
Such then was the received opinion at Benowm, concerning the ^arrt'//^/ 
of Tombuctoo : for, it will appear, that the distance on the Rhiimby which 
determines the difference of latitude, cannot be taken lower, than has been 
stated. 
If the general course of the Joliba, after its escape from the mountains, 
may be admitted to have any weight in the determination of the question 
(since Mr. Park says, that they always pointed along it, to express the line 
of direction, in which Tombuctoo lay), this will point to a higher parallel, 
by about half a degree, than the bearing from Benowm ; that is to 1 6~ 
degrees. And, it may be remarked, that the difference betv,^een these results 
falls yet short of what would have arisen on an error of 5 degrees in the 
bearing ; such as was experienced in that of Sego from Jarra. 
Mr. Park was informed whilst at Benowm, that Walet, the capital of 
Beeroo, was ten journies distant, and this latter eleven journies short of 
Tombuctoo. According to Mr. Park's information, Walet stands at about 
240 G. miles, to the eastward of Benowm; (which would require no less 
than 24 such miles per day, and appears out of rule, unless meant for 
journies of couriers, which is possible enough.) But what is most to our 
point, is, that by the information he received, concerning the position of 
Walet, it appears to lie from Benowm, in the same line of direction which
