Dublin. There are three series of observations from this city, one made at the Coast-guard Observatory during the year 1851, and another at the Ordnance Survey Office, Phoenix Park, for 22 years, from 1831 to 1852 inclusive. The latter were originally recorded for 16 points of the compass, but were reduced, for publication, to eight points, in the same manner as at Nijnii Taguilsk (Zone 7, No. 126). They were also reduced so as to be expressed in parts of 100 (or parts of 1000, by removing the decimal point). Beside the record of the number of observations, showing the relative frequency of the different winds, Whewell's anemometer was used after the year 1839, and Lind's was added in 1845. The third series extends from the year 1857 to 1867 inclusive, at 9 o'clock A. M.
