7073 ft. ; April 1890 to June 1892, 7274 ft. ; July 1892 to November 

 1908, 7224 ft. ; December 1908 to date, yi}^! ft. Data up to 1902, 

 reduced to the height of 7224 ft., were pubHshed in the Ind. Metl. 

 Memoirs Vol. XVI ; to these as well as to the readings from 1903 to 

 November 1908 a further correction of —.008 was applied to reduce 

 them all to the present height of 'J2t^2 ft. From 1880 to 1888 the 

 observations were recorded at jo'^ and i6'\ local time; from 1889 

 to date at 8'' : the former series were reduced to the latter bv apply- 

 ing the corrections contained in Ind. Metl. Memoirs A'ol. XVII, 

 p. XXVIII. There was a shift in the position of the thermometer 

 shed in April i8<;)o; but no correction on this account was applied to 

 the temperature readings. The position of the rain gage has also been 

 shifted several times without any correction being applied on account 

 of change of site. 



W.\LTAIR (VIZAGAPATAM) 



Height of barometer from start to January 1899 ^^'^ 3^ ft. ; Febru- 

 ary 1899 to July 1 91 8, 226 ft. ; August 19 18 to date. 38 ft. Data up 

 to 1902 were given in the Ind. Metl. Memoirs Vol. X\T, where they 

 were reduced to the height of 226 feet by applying a correction of 

 — .200 determined by comparative readings taken at the two sites. A 

 further correction of +.192 due to the second change of site was 

 applied to all these data together with those of the period extending 

 up to July 1 91 8 to reduce the readings to the latest height of 38 ft. 

 From 1875 to 1888 the oliservations were recorded at 10'' and i6'\ 

 local time; from 1889 to date at 8'\ The former were reduced to 

 the latter by applying the corrections contained in the Ind. Metl. Mem- 

 oirs Vol. XVII, p. XXX. The observatory was removed from 

 Vizagapatam to Waltair, a distance of about 4 miles, in February 

 1899 and again from Waltair to \'izagai)atam in August 1918. 

 Temperature and rainfall figures up to June 1899 are for Vizagapatam, 

 from July 1899 to August 1918 for Waltair and thereafter again for 

 Vizagapatam. No corrections were ai)plied to these readings on ac- 

 count of these changes.
