After 1897 the thermometers were put in a box with double shut- 

 ters and placed on the roof of the building, where there was free 

 circulation of air in all directions. 



As the monthly and yearly means are taken from the monthly pub- 

 lication of the Observatory, and are means of lo daily bihourly obser- 

 vations, the results are somewhat high, on account of the lack of 

 observations between 24'^ and 3''. Nevertheless they give faithfully 

 the trend of the temperature and the variations from year to year.
