RE POUT—1854. 
In August 1848 it rained 6*328 ins. in four days, and J850, September 8th, it 
rained 3*955 ins. in twenty-four hours; the storm in both instances blowing from 
N.W. to N. and N.E. 
With regard to the proportions of rain in the former and latter half of the year, 
they stood thus by the average : — 
For the first six months, January to June, 187465 ins.; for the latter six monthi. 
July to December, 25*8568 ins. The sums uf the mean tempernture of those l»" 
portions thus divided are 208*97 ius. and 291*70, being nearly ouc-tbird higher in 
the latter half of the year. 
If we divide the circle in another place we shall have a very different result. 
From the fourth to the ninth month (April to September) the average tain 
amounts to 18*1572 ins., from the tenth to the third month (October to March 1 
26*4461 ins. Now the sum of the mean temperatures of the first six month" in 
this series, or the summer half-year, is 331*51, and that of the remaining »u 
months, or winter half-year, 172*16. Here the relative quantities of rain renum 
about the same, while the temperatures are reversed.

January. — T he sun in the middle of this month continues about 9 hours cr 
G minutes above the horizon. The temperature rises in the day, on an average' 
ten years, to 25°*46, and falls in the night to 12°*18 ; the difference, 13°'28, ttpf'- 
senting the mean effect of the sun's rays for the month, may be termed the to* 
variation of the temperature. , 
The mean temperature of the month is 18°*84 ; but this mean has a range ' 
1 in ten years, which may be termed the lunar variation of the tcmp*' ra 
The warmest year was 1843, when the winds prevailed from the S.W.; and 
coldest was 1851, when the winds prevailed from the N.W. and N.E. i 
fall- this month risea oo on average of ten years to 30*35h ''"J- 
falls to 28*9012 ms.; Hu, mean range is therefore 1*4503 in. ; but the cxlrtv
