ALLAHABAD 



Height of barometer from start to Decemljer 1885 was 307 ft. ; 

 January 1886 to date, 309 ft. Data up to 1902 were copied from the 

 Ind. Metl. Memoirs Vol. XVI, where they were corrected to the 

 present height of 309 ft. From 1875 to 1888 the observations were 

 recorded at 10'^ and 16^, local time; from 1889 to date at 8'^: the 

 former series were reduced to the latter by applying the corrections 

 contained in Ind. Metl. Memoirs Vol. XVII, p. XXIX. There was 

 a shift in the position of the thermometer shed in 1886, but no correc- 

 tion has been applied on this account. 



BANGALORE 



Height of barometer from 'start to July 1882 was 2982 ft. ; August 

 1882 to December 1892, 2983 ft. ; January 1893 to July 1894, 3019 ft. ; 

 August 1894 to date, 3021 ft. Data up to 1902 were copied from 

 Ind. Metl. Memoirs Vol. XVI. The observatory was shifted from the 

 old site to the new one on January i, 1894 and a correction of —.049 

 determined by over one year's comparative readings at the two sites 

 was applied to the readings to make the two series homogeneous. No 

 correction has been applied for the change of height from 3019 ft. 

 to 3021 ft. which is apparently due to a redetermination of height and 

 not to a shift of barometer. From 1875 to 1888 the observations werQ 

 recorded at 10'^ and i6'\ local time; from 1889 to date at 8'^: the 

 former series were reduced to the latter l)y applying the corrections 

 contained in Ind. Metl. Memoirs Vol. XVII, p. XXIX. No correc- 

 tions were applied to the temperature and rainfall readings on account 

 of the shift in the position of the observatory in 1894. 



BOMBAY (COLABA) 



Height of barometer from start to date was 37 ft. From 1847 ^o 



1874 the data utilised were the means of 24 hourly readings; from 



1875 to 1888 the means of 10'^ and 16'', local time, observations; 

 from 1889 to date the 8'^ readings. The former two series were 

 reduced to the latter by applying the appropriate corrections de- 

 rived from pages XXXIII and XXIX of the Ind. Metl. Memoirs 

 Vol. XVII. 



CALCUTTA (ALIPORE) 



Height of barometer from start to March 1877 was 18 ft.; April 

 1877 to date, 21 ft. Data up to 1902 were copied from the Ind. Metl.
