During the last fifteen years slight earthquakes have occurred in Cornwall on eight occasions, the dates being Oct. 7, 1889; Mar. 26, 1891; May 16 and 17, 1892; Jan. 26, 1896; and Mar. 29, April 1 and 2, 1898. The Pembroke earthquakes of Aug. 18, 1892 (0.24 and 1.40 a.m.), and Nov. 2, 1893, and the Hereford earthquake of Dec. 17, 1896, were also felt in the county. Local earth-shakes, probably connected with mining operations, occur occasionally, as on June 4 and 10, 1902. Under the same heading should perhaps be included the shock of Aug. 27, 1895, near Blisland, which I was led to class as seismic on account of its very elongated, though small, disturbed area.
