and competent mathematicians as Colonel Lambton and Major Everest, 

 and that the latter should have lived to have brought to a" completion 

 the most extensive, and probabl)'-, I may venture to add, also the most 

 accurate measure of the earth that has yet been accomplished. Punnae, 

 the southern extreme, is in latitude 8° 9' 38" ; Kedar Kanta in 31 o 2.' 

 The total arc, therefore, is about one-sixteenth of the entire circumfer- 

 ence. 



On this triangulation as a basis, and on the various lateral series car- 

 ried on by the officers and eleves of the excellent military institution 

 established at the suggestion of Colonel Colin Mackenzie, of the Ma- 

 dras engineers, and ably superintended for many years by Captaia 

 Troyer, the whole of the peninsula south of the Krishna has been 

 minutely surveyed in detail. The whole of the Bombay presidency, 

 Khandesh and the eastern portions of Goojerat only excepted, remain 

 unfinished. Of the Nizam's or Hyderabad territories a large portion 

 has been accurately surveyed. The rajah of Berars, or Nagpoor do- 

 minions, have also been triangulated and surveyed, though with less 

 attention to accuracy. The survey of the Northern Circars by Lieute- 

 nants Sackviile, Buxton, and Snell, completes the portion designated 

 as the Peninsula. North of this, of which the Nurbudda is the boundary, 

 a very large portion under the Bengal presidency has been likewise 

 surveyed, according to the methods already adverted to, that is, route 

 surveys corrected by astronomical observations ; and on the eastern 

 frontier much geographical matter has been added by Lieutenants 

 Wilcox, Pemberton, and Grant. 



But we reserve the more complete and exact details, both of these 

 surveys and of the still more important and valuable surveys conducted 

 by the officers of the Indian Navy, to a future opportunity. — Journal
