Thirteenth Season, 1855-6. 
In October (1855) a great deal of rain fell ; November was 
generally fine, but cold. The greater part of December was 
extremely cold, with severe frosts, some snow, and piercing east 
winds, but the end of the month was warm. January (1856) 
was very variable, butj upon the whole, mild, as was also 
February ; March dry and cold, with piercing north-east winds ; 
April and May generally cold, and May particularly very 
wet ; June and July changeable as to temperature, with little 
rain, and frequently very cold nights until nearly the end of the 
latter month, which, with the beginning of August, was fine 
and hot ; then came heavy thunder-storms with excessive rain, 
but the end of August, and the first half of September, were 
fine, after which again succeeded thunder-storms and heavy rain ; 
and the temperature was generally low throughout the month. 
The mean dew-point and degree of humidity were above or 
about the average in June, July, and August, and somewhat 
below it in September. 
Thus, the winter was upon the whole mild ; the early spring 
dry and cold, and the remainder cold and wet ; . the early summer 
cold and changeable, then came a short interval of fine and hot 
weather, succeeded, about the ripening period, by very heavy
