On the return: 
Kichiomi.—Obs. No. 100....\ = 2 h 4 m 26 s ’0 E.G. 
„ „ 101 „ 25’9 „ 
Mean. X = 2 h 4 m 26 s ’ 0 „ 
Here also the agreement between the two results is satisfactory, ancl for 
the reasons already stated we retain as definite value the mean of the two 
results, as under: 
Kichiomi.A = 2 h 4 m 26 s ’ 7. 
An analogous process is taken for Muyongo, where the latitude 
0=0° 30' 41" N. was obtained by two circummeridians (Obs. Nos. 12 
and 13) observed on going; introducing this value in the calculation of the 
longitude, for which there are two series of altitudes on going and two on 
returning, we get: 
Going : 
Misongo.—Obs. No. 14.\ = 2 h 3 m 56 s ’5 E.G. • 
„ 15 „= 55 s ’8 „ 
Returning : 
Misongo.—Obs. No. 97. X = 2 h 3 m 55 s- 4 E.G. 
„ 98 „= 54 s -6 „ 
or taking the simple mean : 
Misongo. X = 2 h 3 m 55 s ’ 6 E.G. 
Thus we get a third test regarding the practical value of the daily 
corrections adopted for the chronometer. 
And since the results of longitude were repeatedly concordant in a measure 
greater than had been expected, we may proceed to the calculation of the 
elements of position for all the other points determined during the expedition, 
being confident of incurring no serious errors. 
Bujoncjo (near Lake Isolt).—The latitude was obtained by a meridian 
altitude observed on the outward journey (Obs. No. 1), and the longitude 
by two series of altitudes also on going (Obs. Nos. 2 and 3) : 
19th May 0 = 0° 25' 44" N.\ = 2 h 4 m 53 s - 4 E.G. 
„ „ = 2 7 54 • 5 „ 
Bujongo 0 = 0° 25' 44" N.A = 2 h 7 m 53 s- 9 „ 
(Lake Isolt) „ = 31° 58' 28" „
