 and during the night ; this arises from two causes, evaporation 

 during the day and the expansion of the air. 



(2) That the richness increases from January to July and 

 August, and then decreases ; that it varies from 0*005 to 0*018, 

 that is to say, it is three or four times as much in summer as in 

 winter. We find in like manner that it increases in hot countries, 

 that it is greater even at Laghouat than in Marseilles; and we
