 Temperature. 



Hours: Means of temperature are: 1835 to 1886 one third of 



mean oliserved values at 6''. 14'' and 22''; 1887 to 1920 one 



fourth of the mean observed vahies at 7'', 14'^ and twice 2i'\ 



Site: The station was moved in 1853, since then it has been in 



the same place.

Hours: The means are ?. (7''+ i4'' + 2i''). 

 Temperature. 



Hours: From 1851 to June 30, 1857 the means are ^(6^+14''' + 

 22'^). Fnjm July 1, 1857 to ig20 they are [(7''+ I4'^ + 2I^^ + 

 2Ih)• 

 //<';r7//^.y.• The height of the station, H, was 20 m. ; after June i, 

 1887 it was 15 m. ; and after October i, 1889 it was 3 m. 

 The height of the thermometers above ground were 1851 to 

 June 30, 1887, ht = 2.8 m. ; July i, 18S7 to September 30, 

 1889, ht= 1.4 m. ; October i, 1889 to 1900, h, = 1.5 m. ; 1900 

 to 1920, ht = 2.o m. 

 Silc: On July i, 1887 the station was removed from the astro- 

 nomical observatory to the nearby Botanical Garden and the 

 thermometers exposed in a wild shelter. In October 1889 

 the station was removed to another site in another part of 

 the lower part of the city and exposed in a shelter of the 

 English type. 

 Error: From 185 1 to 1855 the mean temperatures are about 

 0.5° C. too high.

 Pressure. 



The mean pressures are obtained from direct readings of a large 

 Fortin barometer No. 438 (j. Boulan) and from hourly 

 readings of a Richard siphon barograph. The values are only 

 reduced to zero centigrade. 

 Tem perature. 



The means are for 24 hours derived from direct oljservations at 

 C^, 12^^ and 19'' (Greenwich Mean Time) combined with
