It will thus be seen that the Winter, although milder than the 
preceding three, was rather colder than the average, and consider- 
ably drier. The spring was warmer than three of the preceding 
four, but 1 degree under the average, and the wettest of the five. 
The summer was warmer than in 1885 and 188G, and considerably 
warmer than in 1888, but colder than in 1887, and about 
1 h degrees below the average, and was wetter than in any of the 
series, even the preceding wet summer, the excess being nearly 
21 in. The autumn was, like the preceding, in close agreement 
with the average temperature, much warmer than in either 1885 
and 1887, but coldor than in 1S8G, and was wetter than the 
preceding three autumns, but very much drier than the 
excessively wet autumn of 1885.
