Barometer.—The highest reading of the barometer occurred 
on the 5th December, on the evening of which day it stood at 
30°725 inches—the highest reading for the last four years. The 
lowest reading was on the 7th October, when the mercury fell to 
28.445 in. On that occasion a very deep depression moved from 
south-west to north-east, the centre of which passed over the north 
of Ireland and the extreme south of Scotland, and about 9 A.M. 
was very near Dumfries. A large amount of cirrus cloud in the 
afternoon of the previous day, with a backing wind and a falling 
barometer, gave premonition of the approach of a cyclonic disturb- 
ance ; and the fact that at the hour mentioned, the wind, when the 
barometer was at the lowest, was comparatively moderate, though 
it had been very strong and squally during the night, was an 
evidence that the centre of the cyclone was then passing over this 
district. Between 9 P.M. on the 6th and 9 A.M. on the 7th, twelve 
hours, the fall in the barometer was 1-072 in. The range for the 
year was 2°280 in., and the mean pressure (reduced to 32 deg. and 
sea level) was 29°925 in.—very nearly the average of the three 
previous years. Low barometer readings, ranging from 289 in. to 
. 29°2 in., occurred in January, February, March, April, August, 
November, and December, and were for the most part accompanied 
by storms of wind and rain, but the year has not been exceptional 
in this respect, and in no case has the mean pressure of any month 
fallen below 29°661 in., which happened in October, the month in 
which most rain fell. In January, June, September, November, 
and December the mean pressure exceeded 30 in., and in all these 
months the weather was of a favourable character. 
Temperature.—The highest temperature of the year was 
recorded on the 22d June, when the maximum reading of the ther- 
mometer was 82°4 deg., as compared with 83°6 deg. on 26th June, 
1888, and 87 deg. on 25th June, 1887. It is worthy of remark 
that the highest single day readings during the past three years have 
‘occurred in June, about or shortly after the summer solstice. The 
mean temperature of June last was also the highest of the year, 
viz., 59°8 deg., as compared with 57:8 deg. in July, and 57:7 deg. 
in August, though as a rule the highest mean temperatures usually 
occur in Jnly. From the 14th June to the 6th July, there was 
very bright sunny weather, during which the maximum readings of 
the thermometer ranged from 64 deg. to 82°4 degs., and the 
minimum from 46 deg. to 54 deg., and no rain fell, and in all 
during the summer there were 46 days on which the maximum
