Aurora observed on 1 night, viz.: 22nd at 10 p.m; possible to see Aurora on 17 nights;

Temperature-This month was the coldest April that has occurred during the
last 18 years being 507 below the average. It shews also the lowest maximum tem-
perature, and with one exception the lowest minimum temperature during the same
period.

Rain and Snow-The quantity of rain was small, being 0.783 inches below the
average; but it was more than compensated by the great depth of snow that fell
which was 10.29 inches above the average or about five times the usual depth. The
total moisture was thus 246 inches above the mean.,

Wind-This was the most windy April on the records of the observatory, the
velocity of the wind being 3.17 miles above the average of ten years.

The Resultant Direction and Velocity from 1848 to 1857 inclusive for the month
of April were N. 199 W., 1.93 miles per hour.
