The detached thermometer was in an open northern verandah, the 

 moistened bulb thermometer was inside the house. The barometer 

 was a plain tube with brass scale. The barometer tube was filled with 

 unboiled mercury, and the air gathered and extracted by repeatedly 

 reversing it. In the " Gleanings," for October, 1 831 , I mentioned the 

 altitude of Barelly, gained from a few observations, as about 1080 feet. I 

 was surprised at the result myself, but could not account for it. 1 think 

 I must have made some mistake in recording the observations, or per- 

 haps in adjusting the scale to the tube. The barometer with which 

 the above observations were made was precisely similar to the former 

 one, but not the same. A set* of 10 observations in May, compared 

 with those of the corresponding times in Calcutta, gives altitude of Ba- 

 relly, feet 742.29. Another set of 10 observations in the same month, 

 feet 745.58 ; a 3rd set of 10 in the same month, feet 730.32, and a 4th 

 set of 10 gives feet 755.4, and a set of 31 observations in June gives, 

 feet 753.35. With the former tube and scale, a set of eight observations 

 in May, 1830, gave the altitude of the " oaks" at Masuri, 6796 

 feet above Calcutta ; with the same barometer in November, the same
