Barometer.—The highest reading of the year was on the 17th 
April, and reached 30-632 inches ; the lowest on the 3rd November, 
28°537 m. Annual range, 2°095 in.; and mean pressure (at 30° 
and sea-level), 29°964 in. In 1886 the range was 2°923 in., and 
the mean pressure 29°800 in. The month in which the greatest 
fluctuations of pressure occurred was November, when the range 
was 1°784 in.; but it was considerable also in January and in 
September and December. In June, when the weather was 
remarkably fine and settled for several weeks in succession, the 
range did not exceed 0°731 of an inch, and the mean pressure of 
the month was unusually high, being no less than 30:192 in. But 
the highest mean pressure of the year was in February, viz., 
30°205 in., with readings ranging from 29-304 in. to 30°600 in. 
In the months from February to June, inclusive, anti-cyclonic 
conditions for the most part prevailed, and the mean pressure in 
each was over 30 inches (mean of the five months 30:100 in.), 
with a rainfall very much below the average. In 1887 there has 
been no such excessive fall of the barometer as occurred in Dec- 
ember, 1886, and the storms which were at times experienced 
were only of moderate violence, and did little damage, at least in 
this part of the country. 
Temperature.—The highest temperature of the year occurred 
on the 25th June, when the thermometer rose to 87°, and the 
lowest on 8th February and 22d December, when it fell to 21°, 
giving an annual range of 66°. The mean maximum for the year, 
as will be observed from the tabular report, was 54°8°, and the
