(c) Childing Kona Pass. This station is fixed from the Magnetic bear- 

 ing of Raldang combined with the protracted latitude. These are 208° 54' 

 and 31° 37' It)."" The longitude of the Pass is found to be 78° 27^27"" and 

 from the observed angle of elevation the height is deduced to be 12,880 

 feet. ^ 



(d) Hangarang Pass. Similar Data. The bearing of Raldang 200° 16" 

 The protracted latitude 31° 47"34."" The longitude is found to be 78° 30" 

 50." The elevation from an angle of 3° 04" 10'" 14.7 10 feet above the sea. 



(e) Tashigang. Similar Data. Bearing of Raldang corrected for decli- 

 nation 215° 51'. Protracted Latitude of place of observation 31° 50" 05"'. 

 Angle of altitude 2° 57' 50". Results— Longitude 78° 39' 12'". Elevati- 

 on 12,874 feet. The latitude of the place as derived from observation was 

 31° 49" 54'" but as it is close under the great Peak Purkyul a projection of 

 which has an altitude of 19° or in feet 10,000 nearly, I have allowed my- 

 self to increase the latitude 11', by which means its place is less distort- 

 ed in the protraction than it otherwise would be. The Peak is to the 

 north of the station and the effect of its attraction must have been a di- 

 minution of the latitude. 



5. From the five positions of which the above details are given one or 



two others are obtained in a still less direct manner. At Shipki a small base 



of 1 18 feet 6 inches was marked by well defined signals, and the angle which 



it subtended at a point on the ridge above, was measured by a Theodolite 



well levelled and found to be 3 T 40'", 30' 20", 29' 30'", mean 30' 30". This 



gives 12,850 feet, as the horizontal distance of the ridge. On this line as a base
