Camp 97. Lat. 35° 41' 10", long. 81' 48' 57". The longitude of this camp is determined as below :--

The longitude throughout Peak 42, being discordant, is rejected. The mean of the rest is accepted.
Camp 116. Lat. 35° 52' 46", long. 81° 30' 23". The longitude of this camp was computed through Peaks 28, 37 and 113 of Camp 97, and Peak 58 of Camp 98. The value deduced through Peak 28, being discordant, is rejected. The maximum difference between the other values is 25" ; their mean has been accepted. The latitude comparison is satisfactory.
Camp 73. Lat. 36' 14' 18", long. 81° 30' 59". The longitude of this camp is computed through Peaks 41 and 66 of Camp 100, and Peaks 119, 28 and 115 of Camp 116. The latitudes of Peak 119, as deduced in two camps, differ by 2' 29" ; the longitude through this Peak is therefore rejected. The mean of the remaining four has been accepted. The probable error in longitude, neglecting the probable error of the initial longitude, is 1".
Camp 67. Lat. 36° 30' 42", long. 80' 47' 32". The longitude of this camp is computed through Tekilagh Tagh (A) (identical with Kuin Lûn No. 2, of Synoptical volume vii. of the G.T. Survey of India) and Peak 37 of Camp 97, and by azimuth and difference of latitudes through Peak 12 of Camp 73. The last determination, being discordant, is rejected. The latitudes of Tekilagh Tagh (A), as deduced in this camp and in the Synoptical volume vii., differ by 28", and the latitude of Peak 37, as deduced in Camps 97 and 67, differ by 30". The remaining two values of the longitude agree within 29" ; their mean has been accepted.
Camp 84. Lat. 36° 47' 8", long. 83° 50' 22". As there is no trigonometrical connection of this camp with any of the previous camps, an attempt was made to determine the longitude by chronometer comparison from Camps 73 and 96. The values by A and C chronometers in Camp 73 are 83' 57' 44" and 83° 42' 59". As there was no comparison of C at Camp 96, the value deduced by the only
