II.—Geodetic Observations. 
To this side were connected all the points, Bnjongolo included, which 
formed the apexes of the network in which was comprised all the surveyed 
section of the Ruwenzori Range. 
At all these points a station was made by measuring both the vertical and 
the horizontal angles by means of a prismatic compass from F. Barker and Son, 
London, Xo. 1926, except only for the two extreme points^ and B of the base, 
where was employed the tachometer, and for the Cagni Peak, at which the 
observations were carried out with a small field theodolite. 
In the tabulated Summary A are indicated all the triangles dealt with, as 
well as the value of the observed angles and that of the calculated sides. 
The Summary B contains the orthogonal co-ordinates of all the points 
referred to the extreme west of the base B. 
In the Summary C are brought together the heights of some points which 
are referred to Bnjongolo, and were obtained by means of geodetic observations. 
Lastly, Summary I) is an epitome of the heights that were adopted for all! 
the points indicated on the maps, as well as the method by which said numbers; 
were deducted.
