The idea that earthquakes had a periodicity dependent upon the position of the heavenly bodies is by no means confined to Europe. In a Japanese work called ‘Jishin Setsu’ (an opinion about earthquakes) by a priest called Tensho, it is stated that the relative positions and movements of the twenty-eight constellations with respect to the moon cause earthquakes. This Tensho asserts after careful calculation, and Falb tells us that all future earthquakes can be predicted. In the Kuriles and Kamschatka, Sicily, and in parts of South America, it is said that the equinoxes are regarded as dangerous seasons. _Frequency of earthquakes in relation to the seasons and months._—What is here said respecting the relative frequency of earthquakes at the different seasons and months is little more than an extension and critical examination of the results which have been given respecting the frequency of earthquakes in regard to the position of the sun. That there is a difference between the number of earthquakes which are felt at one season of the year as compared with those felt at another is a fact which, as seismoscopic observations are extended, is becoming more and more recognised. Some of the more important results which were arrived at by Mallet from 5,879 observations made in the northern hemisphere, and 223 in the southern hemisphere, may be expressed as follows:— +---------------------+------------------------+-------------------+ | | Maxima | Minima | +---------------------+------------------------+-------------------+ | Northern Hemisphere | January, also a slight | May, June, and | | | rise in August and | July | | | October | | | Southern Hemisphere | November, also May | March, extending | | | and June | over one month, | | | | also August | +---------------------+------------------------+-------------------+ Julius Schmidt, of Athens, who so carefully examined the earthquakes of eastern Europe, came to the following conclusions:— For the earthquakes between 1200 and 1873, a maximum on September 26 and January 17; a minimum on December 3 and June 13. For the earthquakes between 1873 and 1874, a maximum on March 1 and October 1; a minimum on July 7 and December 15. For all the earthquakes of eastern Europe, a maximum on January 3; a minimum on July 8, or there was a maximum at perihelion and aphelion.
