 elevations 6,900 to 7,400 feet, with the differences of temperature 

 between Calcutta and Dorjiling.

These, it will be seen, give a result which approximates to that 

 of the sets I and II. Being deduced from observations at different 

 exposures, the effects of these may be supposed to be eliminated. 

 It is to be observed that the probable results of the addition of 

 November and December's observations, would be balanced by those 

 of May and June, which are hot moist months. 



IV. — Miscellaneous cold weather observations made at various eleva- 

 tions between 1000 and 17,000 feet, during my journey into east 

 Nepal and Sikkim, in November to January 1848 and 1849. 

 The equivalent to 1° Fahr. was deduced from the mean of all the 

 observations at each station, and these being arranged in sets 

 corresponding to their elevations, gave the following results.
