At the times of full moon the winds were from the N.E. 
and N. W. quarters on 87 days, but at the times of new moon 
on only 44 days, thus confirming the conclusion to which I 
had been led by the results of the temperature observations. 
A similar grouping of the direction of the wind at 1 p.m. 
on the days of first quarter of the moon and two days before, 
and two days after; and also on the days of last quarter, 
and two days before and two after, gave the following 
results

From these two tables of wind frequency we find that 
the relative frequency of northerly and southerly winds at 
1 p.m. during the winter months under the different phases 
of the moon is as follows : —

These numbers show that northerly winds are least 
frequent at and a little after new moon, and most frequent 
at and a little after full moon. On the other hand southerly 
winds are least frequent under the full moon, and most 
frequent under the new moon. 
Taking now the observations of the direction of the wind 
made at 9 p.m. we obtain the following results : —
