Harbor and 125 ft. above Mean Sea Level. Owing 

 to radiation from the slate roof, this station was 

 condemned, and on September 1, 1909, the instru- 

 ments were finally removed to the Albert Park, 

 ^ mile from the Harbor and at about the same 

 altitude. 

 Pressure. 



Remarks: Reasonably reliable pressure observations have been 

 supplied for 1863- 1866, 1868- 1882 July, and 191 6 

 February — 1930. All values have been reduced to 

 Mean Sea Level and to normal gravity (Lat. 45 ). 

 New data preceding 1921 are printed in part III. 

 Hours: The hours of observation were: 



1863-1868 September 9 11 



1868 September-1916 January 9 h 30 m 



1916 February-1930 9 h 



Temperature. 



It seems probable that prior to May 1868, the thermometers were 

 not exposed in a proper screen. The observations 

 are not reliable. The screen used subsequently until 

 1909 was apparently not a good one, probably too 

 massive. Monthly means are probably fairly satis- 

 factory, but the range was too great.

 Site. 



From 1864 to 1880 the Observatory was 21 ft. above Mean Sea 

 Level. From 1894-1904 the rainfall observations 

 were made within \ mile of the present site of the 

 Magnetic Observatory. From 1905 onwards obser- 

 vations were taken at the Magnetic Observatory 

 25 ft. above Mean Sea Level. 

 Pressure. 



Instrument: A Kew Pattern barometer was in use throughout the 



period.
