beginninp; of Aup:uRt, Avliile the coldest period was something like 

 11""5 below the mean for the beginniug of December.

 the fall of the former by -51 in. and of the latter by "GO in., the 

 mean fall for the three years being 27'55 ins. The driest periods

Compared with the seasons of previous years, 1880-81, this table 

 shows that for the "winter months pressure and temperature were 

 higher, while the rainfall was slightly less, than in 1881 ; for the 

 spring months pressure, while about the same as in 1881, was 

 lower than in 1880, and temperature was higher and rainfall 

 greater than in the two previous years; for the summer months 

 pressure and temperature were lower and rainfall was less than in 

 1880-81 ; and for the autumn months pressure was lower than 

 in these years, while temperature was precisely the same as in 

 1881, and only 0°-l less than in 1880. 



I will conclude with a few notes on the months, using the usual 

 abbreviations, i.e. B for bright ; C cloudy ; F fog ; H hail ; L 

 lightning ; M misty ; R rain ; S snow ; T thunder ; T S thunder- 

 storm.
