Temperature. 



Hours: The values are from observations at 8'', 14'' and 21^ 

 calculated according to the following formula, 

 which gives an approximation to the mean of 24 

 hours : 



i|2(8''+i4'')+5X(Ji'V) 1

 Pressure. 



Site: The height of the barometer above Mean .Sea T,evel was: 



1874 to 1918 September 6.8 m. 



1920 January to 1922 August 35.0 m. 



1922 September to 1923 4.0 m. 



All values have been reduced to Mean Sea Level by applying 

 the following corrections : 



1874 to 1918 September +0.6 mm. 



1920 January to 1922 August +3-- "I"''- 



1922 September to 1923 +0.4 mm. 



Hours: The values of pressure do not refer to a fixed hour, but 

 are the mean values of 3 to 6 observations a day. 

 The diurnal variation is negligible in comparison 

 with the variation from month to month. 

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

 45°) by applying a correction of +1.3 mm.
