THE climate of the island of Norderney (lat. 53° 43′ N.) forms the subject of part iii., vol. xxxi., of Ausdem Archiv der deutschen Seewarte. The observations were very carefully made several times a day for nearly ten years (between 1880 and 1890) by the late Mr. O. J. Omtnen; the instruments and exposure were not all that could be desired, but Dr. R. Assmann, of Lindenberg, has taken great pains to correct these defects, as regards temperature, by comparisons with hourly observations at Hamburg, Bremen, & c., the result being that the paper becomes a very useful contribution to the meteorology of the coast of East Friesland. The moderating influence of the sea upon the air temperature is plainly shown; the autumn and winter months have higher, and the summer months lower, temperatures than the Continental stations; the yearly variation at Norderney is only 17.1° C., while at Berlin it is 19.2°. It is interesting to note that the equinoctial gales maintain their old reputation at Norderney, the stormiest months being March and October.
