portion of the Great Meridional Are of India comprised between the 

 Damargida and Delira Dlioon Base lines llf degrees in length, the 

 account of the measurement of which was published by himself in 

 1847. The whole Indian Are is equal to 21°, 21', 16", or about 1469 

 miles. No geodetic measure in any part of the world surpasses, or 

 perhaps equals, in accuracy this splendid achievement. By the light 

 it throws on researches into the figure and dimensions of the earth, 

 it forms one of the most valuable contributions to that branch of 

 science which we possess, whilst at the same time, it constitutes a 

 foundation for the geography of Northern India, the integrity of 

 which must for ever stand unquestioned. 



Col. Everest reduced the whole system of the great national Survey 

 of India to order, and established the fixed basis on which the geo- 

 graphy of India now rests. His determination of the amplitudes of 

 the two Northern sections of the great Meridional Are by means of 

 simultaneous observations taken to the same stars with counterpart 

 circular instruments, and his method of determining the celestial 

 azimuth, still practised, may be considered the most perfect modes of 

 obtaining an astronomical element known to science.
