Appendix B. 



The position of Ih.inda, ;i place lying between Biijoiigolo and Fort Portal, 

 was determined l)()tli on going and returning. From four meridian altitudes 

 (Obs. Nos. 27, 65, 66, and 67), we obtained for this point the latitude 

 = 0° 19' 59" X., and from this were deduced the following longitudinal 

 values : — 



On the outward journey : 



Ibaiida Obs. No. 28 X = 2'' 0" 44'-0 E.G. 



•>Q — 4S -1 



Mean „ = 2'' O-" 43 -5 „ 

 On the return journey : 



Ibaiid.i.— 01)s. No. 62 ... \ - 2^^ 0™ 43^- 9 E.G. 



63 ... „= 41-5 „ 



64 ... „= 42-5 „ 

 m ... „= 42-7 „ 

 69 ... „= 43-5 „ 



Mean „ = 2'' O"" 42^- 8 „ 



Such is the agreement batween these two results that we may even 

 disregard all considerations as to the weights to be adopted for the values 

 obtained, whether as regards the number of concurrent observations, or the 

 length of time during which Greenwich time had to be conveyed. In this 

 case there intervened 22 days for the determination of longitude on going 

 (that is, Greenwich time was conveyed for 22 days), compared with a mean of 

 about 5 days of conveyance for the determination mada on our return. 



Moreover, given the degree of accuracy that may be required, allowing 

 for the available means and the limited time at the disposal of the expedition, 

 we found it advisable to ad(jpt as the value of the longitude of Iliaiida the 

 mean of the two results, namely : 



I banda A = 2'' 0"' 43^-2 E.G. 



In the district between Entebbe and Port Portal there are two other points 

 which ottered the same conditions, and which consequently contributed to 

 supply means of control. For Kichiomi, which is one of these two points, we 

 obtained by the obsei'vation of a meridian altitude both going an<l leturning 

 (Obs. Nos. 10 and 99) the following result : 



Kichiomi = 31' 20" N. 



Adopting this value for the calculation of longitude we obtained on going : 



Kichiomi.— Obs. No. 11 \ = 2^ 4"" 27*- 3 E.G.
