MOON'S PHASES ON THE TEMPERATURE OF 

 THE AIR AT BATAYIA. 



P. A. BEROSMi 



When discussing the hourly observations of the temperature 

 of the air made at the Batavia Observatory du ring the ten years 

 1866 to 1875, I thought it of some interest to investigate 

 whether any variation, dependent on the moon's phases, might 

 be found in them. 



Eight different phases of the moon have been considered in 

 this investigation ; they era denoted by the nunibers (0), (1), 

 (-2), (3), (4), (5), (6) and (7), the numbers (0), (2), (4) and 

 (6) indicating new moon, first quarter, f uil moon and last quar- 

 ter: the numbers (1), (3), (5) and (7) indicating the interrae- 

 diate phases. 



The mean temperatures have been ealculated for the days of 

 eaeh of these moon's phase?, being laken as days of a certain 

 phase not only the days on which this phase feil, but also those 

 days immediately preceding and immediately following them. The 

 mean values obtained in this way for the temperature of the day 

 on the several moon's phases in each of the lustra 1866 — 1870 

 and 1871- 1875, and in the decade ï 866— 1875, are given 

 in the columns 2, 3 and 4 of Table I ; the three last vertical 

 columns of this table exhibit for each of these periods the dif- 

 ference^ of the eight values, obtained for the several moon's
