te.rieclion ff the bearings and by calculation. Colonel Crawford- had 

 alio taken altitudes; from, which the. height -of the mountains miohtbc i 

 computed, and which gave, after due allowance for re fraction, the 

 elevation of confpicuous peaks, at least equal ta that abovemen- 

 tioned. But the drawings and journal, v of. this, survey have been un- 

 fortunately lost. .; ,

TnEf©bfervations instituted and completed by Lieutenant Colonel 

 Col eb.rooke, while in Rohilkhand, were jfcwo: one taken at Pilibhit, where 

 the elevation of a peakdillant; 1 1 4 ,'$ nglifli miles, according to bearings 

 frpm two Rations, the di fiance between which was meafured, \*jas found > 

 to be i° 27'; the Q\h^^\J:efhpur y sft}\±x£ the elevation of the fame peak;.
