In the next table I give the fall of rain for 1877, during 
the day from 8 a.m. to 8 p.m., and the fall during the night 
from 8 p.m. to 8 a.m. From 1868 to 1873 the day fall is 
always greater than the night fall. In 1874 the night fall 
was in excess, and in 1875 the day fall was again in excess ; 
and in 1876 and last year the night fall was in excess, but 
at most, either way, the difference between them is very 
small.
