Bruxelles, XVIII (1844), Comptes Rendus, LII, p. 146; R. Falb, Grundzüge einer Theorie der Erdbeben und Vulkanenausbrüche, Graz, 1871, and Gedanken und Studien über den Vulkanismus, etc., 1874; Pfaff, Allgemeine Geologie als exacte Wissenschaft, Leipzig, 1873, p. 224; Schmidt, Studien über Erdbeben, 2d ed., 1879, and Studien über Vulkane und Erdbeben, 1881; Dieffenbach, Neues Jahrb., 1872, p. 155; M. S. di Rossi, La Meteorologia Endogena, 2 Vols., 1879 and 1882; J.

Records of earthquakes have been preserved more or less fully in several countries, especially in recent years. A few of the more accessible publications where these records are found are cited below: California earthquakes, Perrine, Bull. 147, U. S. Geol. Surv.; Earthquakes of the Pacific Coast, Holden, Smithson. Misc. Coll., No. 1087, 1898; Records of recent earthquake movements in Great Britain since 1890 are published by Davison in Quar. Jour. Geol. Soc., Geol. Mag., and Nature; Records of earlier earthquakes are found in the reports of the Brit. Assoc. (Mallet), in the Edinburgh New Philos. Jour., Vols. XXXI-XXXVI (Milne), and in Trans. of the Roy. Irish Acad., 1884 and 1886 (O’Reilly); The Earthquakes of Scandinavia have been recorded in volumes of the Geol. Fören, Förhandl.; Records of other continental European earthquakes are found in Gerland’s Beiträge zur Geophysik, 1895, 1900, and 1901; Neues Jahrb., 1865–71; Zeitschr. Naturwissen. (1884), (Credner); Bericht. k. Sachs. Geol. Wissen., 1889 and 1900 (Credner); Jahrb. Geol. Reichsanst., 1895 and 1897; Tschermak’s Min. Mitth., 1873, and later; Transactions of the Seismological Soc. of Japan. An index to these Transactions is given at the end of Milne’s Seismology.
