giving an annual range of 1*866 in. The mean barometrical 

 pressure (reduced to 32 degs. and sea level) was 29-901 in., which 

 is a little above average. In March, April, and July the mean 

 monthly pressure was slightly in excess of 30 inches. The 

 lowest monthly mean was in October, which showed 29 706 in. ; 

 and on the 9th of the same month there was a fall to 28 '956 in. 

 But neither on that day, nor in the beginning of February, when 

 the barometer fell to a still lower point, the lowest of the year, 

 was the fall accompanied by such severe storms of wind or 

 excessive rainfall as are often experienced in connection with 

 such depressions, although the weather was squally at times, 

 and especially during tlie night. But on the whole there was a 

 marked absence, at least in this district, of storms of any 

 intensity. 



Temperature (in shade, 4 feet above the grass). — The highest 

 reading of the self-registering protected thermometer was 82 

 degs. on the 9th June, and only once again (in August) was the 

 maximum of 80 degs. reached. The lowest temperature registered 

 was 9 degs. on the 26th December, giving an annual range of 73 

 degs. On one other night, in February (the 19th of the month), 

 the thermometer registered a minimum nearly as low, viz., 9*3 

 degs. These were the lowest readings of the year ; but there has 

 been an unusual number of instances in which the temperature 

 fell to and below the freezing point — in January, for example, 

 16, with an aggregate of 73 degs. of frost ; in February, 11, with 

 an aggregate of 66-7 degs; in March, 23, with an aggregate of 

 112 degs. ; in April, 12, with an aggregate of 52 degs ; in October, 

 8, with an aggregate 34*7 degs. ; in November, 5, with an 

 aggregate of 14-8 degs. ; and in December, 21, with an aggregate 

 of 173-8 degs. There were thus in all during the year 96 days on 

 which the thermometer fell to and below the freezing point, with 

 an aggregate of 557-5 degs. of frost. On the other hand, the 

 number of really warm days on which the thermometer rose to 

 70 degs. and above was comparatively few, viz., 21, the most of 

 which occurred in July and August. The warmest month was 

 August, with a mean temperature of 58 degs. July came next 

 with 57*7 degs. June had only 55-7. The coldest month was 

 December, with a mean of only 34 degs., which is 4J degs. below 

 the average. March was also a very cold month, the mean of 

 37*4 degs. being less than that of February, and nearly 5 degs.
