254 ON THE HEIGHT OF THE 



ings of the range, that the mountains, which they then viewed, are 

 the fame which are feen from Pumea t Rajmahl, and other places in 

 Bengal* Now, according to the furvey of Captain Turner's route, 

 Chamaiari is placed in Lat. 28° 5' Long. 89 18' ; a pofition no lefs than 

 165 geographic miles from Purnea\ and 200 from Rajmahl, which 

 is (ituated in Lat. 25° 3' and Long. 87 44 by observation + From 

 a commanding eminence on the frontier of libit, the travellers had an 

 extenfive view of the mountains of Butdn, covered with verdure to 

 the very tops ; and it appears from what is faid by them, that Butdn 

 contains no mountains on which fnow continues during all feafons of 

 the year, and few on which it remains until the middle of fummer. 

 Thefc circumflances feem toeflablifh beyond queftion, the fa£l, that the 

 fnowy range, of which Chamaiari ha. part, is that which is feen from 

 Nations in Bengal, diflant 165 and even 200 Geographic miles, anfwering 

 to 191 and 232 Britijh miles. Now it requires an elevation exceeding 

 28,000 feet to be barely difcernible, in the mean ftate of the atmofphere, 

 at fo great a diftance as that laft mentioned ; though a much lefs eleva- 

 tion, it mull be acknowledged, may fuffice under circumflances of ex- 

 traordinary refraction. 



Thi prefumption, which was however raifed on thefc grounds, was 

 to my apprehenfion corroborated by observations, which I had my felf 

 the opportunity of making twenty years ago ; and which gave, accor- 

 ding to the note I have prefcrved of them, i° 1' for the ufual altitude of 

 a confpicuous peak of the Himalaya viewed from a ftation in Bengal, 

 which, according to the conduction of Rehkel's map, was not lefs
