and this must necessitate a fresh arrangement of symbols, 

 the present being merely an enumeration of the peaks al- 

 ready known, in order of sequence, from East to West : I find 

 that a similar arrangement has been adopted by the Russian 

 surveyors in their published synopsis of the co-ordinates 

 of the stations of the Russian survey: even where the 

 places are well known, it is found convenient to refer to them 

 by numerals, arranged in order from North to South, as well 

 as by their names ; but, of course, when additional positions 

 are determined, the existing numerical arrangement must 

 be altered. We have adopted Roman numerals with no 

 other object than to prevent confusion with the Italian 

 numerals that are employed in giving the elements of lati- 

 tude, longitude and height, which are usually written on 

 our charts by the side of the symbolic name. 



Certain erroneous inferences might be drawn from Herr 

 Schlagintweit's paper, which I am sure no one will be more 

 obliged to me than that gentleman himself for here point- 

 ing out 



First That the snowy "peaks enumerated by himself are 

 all that have been hitherto measured in the Himalayas. 

 They comprise all of which the positions have hitherto 

 been published, as far as I know to the contrary ; but they 

 do not comprise a fifth part of the number already measured 

 by the officers of this survey. 



Secondly. That none of the peaks to which he assigns the 

 3rd degree of accuracy have been measured by the G. T. 

 Survey. Of these, there is an important group in the district 

 of Ranaur. Herr Schlagintweit's figures are all but identicaj 

 with the values given in the published " Chart of the first 

 section of the North West series ; 1847-1854." It is evident 

 that they were derived from that source only, and that the 

 few differences which exist are merely due to errors in copy- 

 ing the original. Besides which, the source from which
