MYERS ON METEOROLOGY. oB 



The hottest month was August: the coldest January. The 

 mean temperature was the same as last year, vi2 : 43. 



The highest reading of the barometer during the year wai 30. 

 35, on the 14th March; the lowest 28.51, on 21st December. 

 The highest monthly range Avas 1.59 in December; the lowest .59 

 ^n July and September. The yearly range was 1.84. The meaii 

 for the year 29.65. 



The annexed table (see appendix j, gives the monthly and yearly 

 means and range of the temperature, and atmospheric pressure for 

 the years 1863, 1864 and 1865, deduced fi-om three daily observa- 

 tions. The comparison of these three years, one with the other, 

 exhibits a remarkable equability as well in the monthly, as in the 

 annual results. 



The most prevalent winds during the year were K.W. and S. 

 W. ; the least prevalent E. 



Rain fell on 136 days ; snow on 52 ; hail on 3 ; fog occurred 

 on 60 days. 



Auroras Boreales were observed on 55 nights; solar halos on 5 

 days; lunar halos on 12 nights; thunder storms occurred on 4th 

 March ; 25th May ; 29th July ; and 23rd October. Lightning was 

 seen, but thunder not heard, on 23rd June ; and 1st September. 

 Thunder was heard, but no lightning seen, on 9th and ITth May. 



The latest snow in the Spring fell during the night of 6th, Tth 

 May ; and its earliest appearance in the autumn was observed on 

 the forenoon of 21st October. July was the only month entirely 

 free from frost. 



The weather during the year was genci-ally fine. The winter 

 of 1864—5 was remarkably mild, and broke up early. A humid 

 spring was succeeded by an extremely dry summer, occasioning 

 ndeed inconvenience in some localities, but favourable to the hay 

 crop, which throughout the country Avas abundant and of excellent 

 quality!; ^^^' *^^^^ ^^ appear that other crops suffered to any great 

 extent from the dryness of the season. 



Drought, with the temperature above the average, seems to 



have been, in the past two summers, the abnormal climatic condition 



of many parts, not only of the American, but also of the European 



Continent ; followed this year by great atmospheric disturbance iii
