Site: 1897 to 1901 August. Observations taken by the Rev. 

 Father Nicot at St. George's School, at the same 

 height as the present site (4440 ft.). 



1901 September to December. 01)servations taken at the 



Railway Station at a height of 4469 ft. 



1902 January to 1903 May. C^bservations at St. George's 



School. 



1903 June to 1923. Observations by the Rev. Father Goetz 



at the Observatory at a height of 4440 ft. 



For the notes on the height of the station, see Introduction 

 to Salisbury, Rhodesia. It is probable that the 

 height of Bulawayo, like that of Salisbury, needs 

 a correction of between —30 and —60 ft., but this 

 has not yet been determined. 



The values of 1901 September to December have been re- 

 duced to a height of 4440 ft. by applying a correc- 

 tion of +0.026 in. 

 histrmuent: A Kew pattern barometer, index error correction 

 + 0.014 in. has been in use throughout the period. 

 Hours: 



1897 to 1903. 9^' (30th Meridian time). 



1904 to 1923. 8^ (30th Meridian time). 



The values for 1904 to 1923 have been corrected to 9*^, by 

 applying the following corrections : 



Jan. Feb. Mar. Apr. May June July Aug. Sept. Oct. Nov. Dec. 

 Inches .000 rf.OCS +.004 +.005 +.007 +.015 +.018 +.014 +.007 +.004 +.003 .000 



Notes: All values have been corrected to normal gravity (Lat. 

 45°) by applying a correction of —0.053 "i- 

 Prior to January 1904, the pressure data may be unreliable. 

 A correction of —.100 in., obtained by comparison 

 with the Salisbury readings, has been applied to 

 1897 November and December; 1898 January; 

 1899 '^fay ^"^I June.

Site: As for Pressure. 



Exposure: Prior to January 1904 the thermometers were ex- 

 posed in a small-sized Stevenson screen. Since that
