THE PEAKS IN THE HIMALAYA 



II. The latitude aod longitude of peaks measured with 

 the second degree of accuracy is correct within 10 to 15 

 seconds, and the height within 70 to 90 feet, 



III. The latitude of the peaks measured with the third 

 degree of accuracy may be wrong within 2 to 3 minutes, the 

 longitude within 3 to 6 minutes, and the height within 10O 

 to 200 feet. None of the peaks of this category have hitherto 

 been measured by the G. T. Survey. 



Besides, the geographical co-ordinates of all the peaks 

 hitherto measured in the Himalaya, depend upon the cor- 

 rectness of the following data : 



1. On the latitude of the G. T. Station of Kalsanpur, for 

 which the value of 24° T 11^26 is adopted, 



2. On the longitude of the Madras Observatory, for 

 which I have adopted the value 80° 13' 55f\5 East of Green- 

 wich, in conformity with the Admiralty and Royal Astro- 

 nomical Society. The old value for the Madras Observa- 

 tory, as adopted by the G. T. Survey is 80° 17' 21." 



3. On the mean sea-level as observed in Kydd's dock- 

 yard at Calcutta. 



The peaks contained in the following enumeration are 

 arrayed according to geographical provinces, and within 

 them from East to West. Among the'216 peaks contained 

 in the enumeration, 17 exceed the height of 25,000 feet, 40 

 the height of 23,000 feet, and 120 the height of 20,000 feet. 

 One of the 216 peaks actually reaches the height of 29,002 

 feet (Gaurisankar, or Mount Everest), and another the height 

 of 28,156 feet (Ranchinjinga West). The relative number of 

 the other peaks exceeding the height of 20,000 feet, are ;
