. Bulletin of the Southern California Academy of Sciences. Science; Natural history; Natural history -- California. report for 1850, p. 66. It is referred to by Dr. :\Iallet as hav- ing been compiled by L. F. Kontz and originally published in the Allgemeine Encyklopadie der Wissenschaften und Kiinste, von Ersch und Gruber, Thiel, 36. This list, compiled by a German authority previous to 1851, comprehends a dif- ferent series of earthquakes, and must be taken as indepen- dent of the data employed by Mr. Fig-. 2. ]\[onthly Distribution of Earthquakes. German Statistics. Total 882. Here we have a curve not so striking as that shown in figure 1 but still showing the same characteristics, with the maximum in the season of the autumnal equinox and minor rises in the three other seasons. It should be borne in mind that the old data employed, while gathered from a much wider field and coinprising a larger number of earthquakes, is probablv less reliable and complete. The curve formed upon the Charleston data, gathered in a single restricted and well defined seismic area, and doubtless more accurately com- piled, ought to be the better testimony, furnishing the more typical curve. For a third trial, we turn to another distinct and far-dis- tant field, this time employing statistics compiled by Baron Dairoku Kikuchi, and published by the Japanese Imperial Earthquake Commission in its Report No. 19. Here again we have the same general characteristics in a modified "form and with sufficient variation to make the study interesting. Still the maximum point is in the autum- nal equinox. See figure 3. Again we shift the field and take data of Pacific Coast earthquakes from 1850 to 1887 inclusive, compiled by Profes- 11.
