230 Meteorological Observations at Masuri. TApim,, 



I do not publish these observations with the idea that they are 

 sufficiently numerous to establish any general law on the subject for 

 this country, but because my avocation here does not permit me to 

 extend them, and in the hope that some one who may hereafter travel 

 through the Bikanfr country may be induced to take up the subject, 

 for there alone can any considerable depth beneath the surface be 

 attained. 



P. S. — Lieutenant Tremenheere, of the Engineers, in leaving this 



on the Shekawatti campaign, had the kindness to promise that he 



would make some observations on the temperature of the deep wells 



that lay in his route, and this he has performed with great zeal and 



assiduity. He has now placed the results he obtained in my hands, 



and 1 have drawn up the following abstract of them :

These observations were made throughout a large tract of country 

 lying between 28 and 26° N. Lat. and 78 to 76° E. Long. And the 

 time of the year in which they were made was from the 26th October 

 to the 28th February. The mean temperarure of the year for the sur- 

 face may be reckoned at 75°, if, as stated by Lieut.-Col. Oliver, that 

 of Dehlibe7S°. 4. 



I see that in the above paper on this subject I have misquoted this 

 same datum of Colonel Oliver's, calling it 76°. I took the number 

 carelessly from the wrong column, owing to its suiting so well to Dr. 

 Royle's observations at Seharanpur, who makes the mean of that 

 place, I believe, 73°. 5. One or other of the two observations must 

 now be rejected.

* I think that the temperature at 10 a. m. and 4 p. m. was considerably raised 

 by reflection. This was modified or obviated in the subsequent months.
