tape measure and stadiometer, the distances intercepted between the points 

 B c, c c, c' (I, d A, from which were had the following results : — 



At the extreme west point B of the base, the height of which over 

 Bujongolo was also measured with the barometer and found to be 104 metres, 

 solar ol)servations enabled the expedition to determine the azimuth of one of 

 the points constituting the apexes of the triangles of the geodetic network, 

 which thus l)ecame orientated. 



The point chosen for the azimuth was the Cagni Peak, distant 18f<2-9 metres 

 (5,980 feet), and the following i-esults were obtained : — 



Mean of fotu' values on the right 



Circle 80^ 51'- 29. 



Mean of four values on the left 



Circle 80^ 51'- 09. 



Mean value of the azimuth of Cagni Peak from Point B ..80 51 '-19. 



\\'ith the mean value of the l)ase of 288-43 metres (945 feet), and solving 

 the two triangles Ji ./ Cagni Peak and // ./ Edward Peak, we obtained from 

 two parts the value of the side Cagni Peak — lùlward Peak, which gave 

 2883-2 metres (9,456 feet).
