The weather of the year 1885, taken as a whole, presents no 
strongly-marked feature, in this respect being like that of 1883. 
The mean pressure of the atmosphere was a little below the average; 
the lowest pressures recorded were 28'957 ins. on January 11th, 
and 28-995 ins. on October 10th, and the highest, 30-609 ins. on 
March 14th, and 30-611 ins. on December 23rd, giving a range of 
1*654 in. The temperature was a little below the average, and 
there were no excessively high nor excessively low readings, though 
the mean daily range was above the average. The rainfall, although 
less than the average of the eight years of our observations, was 
still considerably above the average of a long period, and the 
number of rainy days was also great. There was a greater pre¬ 
ponderance of N.E. winds, and a less preponderance of S.W. than 
usual. 
Compared with the previous year, in 1885 the mean temperature 
was 2°*2 lower, the mean daily range 0°*5 less, the relative 
humidity 1 per cent, greater, and the rainfall 7-67 ins. greater. 
Dain (or snow) fell on 31 days more in 1885 than in 1884, and
