than the dry bulb thermometer. Had we accepted 

 the readings of the latter in computing the pressure, 

 the difference would have amounted to only --001 

 inches. 



The thermometers were verified at Kew, in the 

 dates mentioned below, and the corrections which 

 had then to be applied to them were as follows : — 



No. 4590 (dry bulb), September 1889 : up to 72°, 

 0-0; at 82°, +0-1; at 92°, +0-1. 



No. 4596 (wet bulb), September 1889 : at 32°, - 0-1 ; 

 at 42°, 52°, 62° and 72°, 0-0 ; at 82° and 92°,+0-l. 



No. 1358 (max. therm.) June 1890 : at 64°, -0-7° 



No. 1458 (min. therm.), January 1891 : up to 32°, 

 0-0 ; at 32°, 42°, 52°, 62° and 7u°,-0-l. 



The instruments are placed in tlie Hall, under the 

 Sub-Commissioner's office, 5 feet from the ground of 

 the floor. The n-iin-gauge stands in the open space on 

 the roof of the office. 



No observations were recorded on Sundays (rainfall 

 excepted), and in 1897 the office was closed also 

 during Jubilee week (June 22-27) and Christmas week 

 (December 25-31). 



The barometrical observations have been reduced 

 to 32° F., and to Standard gravity in Lat. 45°, but not 

 to sea-level. 



The mean temperature is assumed to be the mean 

 of all max. and min., and is therefore too high.
