Barometer. — The highest reading of the year was on the 17th 

 April, and reached 3U"G32 inches ; the lowest on the 3rd i^oveniber, 

 28-537 in. Annual range, 2-095 in. ; and mean pressure (at 30' 

 and sea-level), 29964 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 0731 of an inch, and the mean pressure of 

 the month was unusually high, being no less than 30192 in. But 

 the highest mean pressure of the year was in February, viz., 

 30-205 in., with readings ranging from 29-304 in. to 30600 in. 

 In the months from February to June, inclu.sive, 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. 



Teviperattire. — 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 tiie tabular report, was 54-8', and the
