__Mean for year, (51-48 333 13 52°36 
THe mean temperature for the year 1850 is 519-48, which is 
somewhat less than that of 1849, being 52°09. This depression 
may be found in the low grade of the spring and autumn months; 
the mean for this year being nearly five degrees less in the spring 
than that of 1849, while autumn is about one degree below. 
© summer was warmer by about one degree and a half. The 
greatest heat was in July, the mean for that month being 76°14, 
while July of 1849 was 722-20, 
th ording a scanty supply for the ice houses. In the Ohio river 
ete was much floating ice, but not so abundant as to stop the 
Tanning of steamboats. The temperature was at no time below 
Zero, but stood at one above on the first day of the year. ‘There 
Was a large quantity of rain in January, over five inches, and at 
ime the rivers threatened an overflow of their banks. Feb- 
Tuary usually furnishes the coldest weather of any of the winter 
oka but this year the mean was five degrees above January. 
PPR of one day, the fourth of this month, was below that 
‘ny other, being only eight degrees, while the lowest in Jan- 
nary was thirteen,
