The following paper is a continuation of similar records furnished by officers of the Lick Observatory, and completes the list up to the .end of 1893. It records all the shocks observed or felt on Mount Hamilton, and all those reported to the Lick Observatory by letter, as .well as newspaper reports of such earthquakes as occurred in the State during that year. It also includes a number of shocks in various localities on the Pacific coast, which it was thought might not have been recorded in other reports. No systematic examination of newspapers has been made, however, and some reports of earthquakes may have escaped notice.
