In the next table I present the average day and night 
fall for a period ol eight years. The results of this table 
continue to show that the day-fall exceeds the night-fall 
so far as the whole year is considered. The months which 
have an excess of rainfall in the nights are those which 
show the greatest amount of atmospheric vapour, namely 
January, February and December; August and September 
show an increase, but in these months the amount of vapour 
in the air begins to increase, but whether the excess in those 
months is due to that cause is yet doubtful.
