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 observations enabled the expedition to determine the azimuth of one of 
the points constituting the apexes of the triangles of the geodetic network, 
which thus became orientated. 
The point chosen for the azimuth was the Cagni Peak, distant 1882-9 metres 
(5,980 feet), and the following results were obtained :— 
Mean of four 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. 
With the mean value of the base of 288 - 43 metres (945 feet), and solving 
the two triangles B A Cagni Peak and B A Edward Peak, we obtained from 
two parts the value of the side Cagni Peak—Edward Peak, which gave 
28832 metres (9,456 feet).
