In the next table I present the average day and night 
rainfall for 6 years. An examination of this table conti- 
nues to confirm the experience of previous years, that the 
day fall exceeds the night fall so far as the amount of the 
whole year is concerned. But curiously enough this table 
of 6 years’ average gives an excess of night fall in the same 
months that were shown in a table of 5 years’ average 
which I read at the Section last year, those months being 
January, February, August, September, November, and 
December. It is however remarkable how close the total 
day and night rainfalls are to each other, for though the 6 
years’ average shows a difference of double that of the 
5 years’, yet it is only about 4 per cent on the total fall.
