the observations of the two years that the ratio of the mean 
velocity of the wind on days- when no rain hills, as compared 
with that on rainy days, varies least in the spring, and most 
in the winter quarter. 
Mr. W. L. Dickinson read a Paper containing the results 
of calculations relative to the Eclipse of the Sun, and to two 
Occupations of the star Aldebaran by the Moon, visible here 
this year. The calculations have been made for the Obser- 
vatory of Robert Worthington, Esq., F.R.A.S., Crumpsall, 
near Manchester, Lat. 55° 30' bO'^O N., Long. 0 h 8 m 56 s, 16 W. 
The Elements used in the computations have been obtained 
from the Nautical Almanac.
