mean pressure — above 30 inches — were July, October, and 

 November, and in these the weather was more settled ; while in 

 May and September it was also favourable on the whole. The 

 mean barometrical pressure for the year was 29 '906 inches, which 

 is just about the average of the last ten years. 



Temperature. — Tlie liighest single day temperature of the year, 

 as shown by the sheltered thermometer in shade, 4 feet above the 

 grass, was recorded on 15th July, when it rose to 86 deg. The 

 lowest was on the 18th January, when it fell to 15 "8 deg., thus 

 giving an annual range of 70'2 deg. The warmest month was 

 August, with a mean temperature of 61-4 deg.; but July fell 

 very little short of it with a mean of 60 "7 deg. These months 

 were both above the average of the last ten years by 2 to 3| deg. 

 There were seven months in which the mean temperature was in 

 excess of the normal, viz., February by 2'5 deg., March by 1'3 

 deg., July by 2-1 deg., August by 3-6 deg., Octolier by 3'1 deg.,. 

 November by 3 deg., and December by 1-4 deg., the aggregate 

 excess amounting to 15 deg. On the other months the means 

 were below the average, January having a deficiency of 2 '9 deg., 

 April of 2-3 deg., May of 2 7 deg., June of 0-2 deg., September 

 of 1'6 deg.; aggregate deficiency, 9"7 deg. As might be expected 

 from this comparison, the mean temperature of the year taken as 

 a whole was above the mean, viz., 48 2 deg., as compared with 

 an average of 4 7 "5 deg. There were 60 nights on which t!ie 

 temperature fell to and below the freezing point, viz., 21 in 

 January, with an aggregate of 113 degs. of frost; 7 in February, 

 with an aggregate of 18'7 deg. ; 7 in March, with an aggregate 

 of 13'2 deg.; 8 in April, with an aggregate of 26'2 deg.; 2 in 

 October, with an aggregate of 12-2 deg.; 4 in November, with 

 an aggi'egate of 10"9 deg.; and 11 in December, with an 

 aggregate of 54-3 deg. Total, 60 nights, with an aggregate of 

 248 degs. of frost. As tliis statement shows, January was by 

 much the coldest month. Mai'ch was a stormy month, with a 

 good deal of rain and some snow, but with a temperature some- 

 what above tlie average. In April and May there was a 

 deticiency of warmth. But in June, July, and August there was 

 rather more than the usual number of warm and sunny days, 

 with a maximum temperature of 70 deg. and above. There were 

 12 in June, 16 in July, of which 4 were from 80 deg. to 86 deg., 

 and 11 in August, of which 4 were above 80 deg., and 2 in 

 September. The warmest period of the year was between the
