328 Meteorological Observations at Hudson, Ohio. 
HUDSON, HANOVER. 
“Vam | SP.m. Sunrise. 14 P. m. 
Spring, 21.0 18.5 | 27.5 21.0 
Summer, LEZ? 5.4 18.5 15.0 
Autumn, 17.0 | 16.0 16.5 16.5 
‘Winter, TD i 9.0 23.0 23.0 
Year, 59.0 A8.9 85.5 75.5 
The number of clear days for the entire year at the two 
places is about inversely as the degree of cloudiness; yet com- 
paring the observations at 14 and 3 P. M. we find the number of 
clear days for spring and autumn nearly the same at the two 
places; while for summer and winter the number at Hanover is 
from two to three times that at Hudson. It must, I think, be 
admitted, that observations of this kind possess considerable in- 
terest ; and considering the ease with which they are taken, it is 
a matter of surprise that they should be almost universally neg- 
lected. To the astronomer they are perhaps the most important 
of all meteorological observations, as they indicate the most suit- 
able site for a public observatory. At Hudson, for example, du- 
ring four months of the year, astronomical observations are 
almost entirely impracticable. = — rae A ae
