MR. A. W. PRESTON 8 METEOROLOGICAL NOTES. 
225 
It will bo seen from the above that the winter was milder than 
the preceding four, but like 1888 and 1889 was drier than the 
average. The spring was of about the same mean temperature as 
in the preceding year and in 188G, but considerably milder than 
in 1887 and 1888. It was nevertheless, like all four of the 
preceding springs, under the average temperature. The rainfall of 
the spring quarter was in almost exact agreement with the average, 
and considerably less than in 1889. The summer, like the 
preceding two, gavo a deficiency in temperature and an excess of 
rainfall (the excess in the latter being 2.J in., which is almost 
identical with that of 1889), and the autumn was milder and 
drier than the preceding three. 
Year. 
The mean temperature of the year was 48 degrees, which is 
identical with that of the previous year, and although this value 
is not much more than a degree below the average, it still shows 
the same tendency to cold rather than to heat, which has been 
remarked in each year since 1884. The only exceptionally mild 
months were January and September, and although March gave 
rather a high mean temperature, owing to the warmth of the three 
latter weeks, the first week of the month was the most severe of 
the whole winter. The month of greatest defect in temperature 
was December, which gave a mean of nearly 9 degrees below the 
average. Next to this come July and August, with deficiencies 
of 4 degrees and 3 degrees respectively. The wettest months 
were July and November, each of which gave over an inch 
of rain more than usual. The driest months were February, 
April, September, and December, in each of which the rainfall 
was under an inch. The total rainfall for the year was about an 
inch under the average. 
N.13. — The instruments from which the foregoing observations are taken 
consist of a Kew-pattern standard barometer, corrected for temperature and 
reduced to sea level, standard maximum and minimum thermometers and 
dry and wet bulb thermometers, mounted in a Koval Meteorological 
Society’s screen, in a freely exposed situation. All the above instruments 
are by N egret ti and Zambra, and have been verified at Kew Observatory. 
The rainfall is measured by a Symons’ Snowdon rain-gauge, and the observa- 
tions of the direction of the wind are, for the most part, taken from the 
vane on the spire of Norwich Cathedral.
