Seismochronograph designed by Arnold Von Lasaulx, Breslau, Germany (now Wroclaw, Poland), c. 1876

The seismochronograph was designed by Arnold von Lasaulx, professor of mineralogy at Breslau (now Wroclaw, Poland). It recorded the time of an earthquake shock by means of a falling ball which stopped a clock. This example was displayed at the Special Loan Collection of Scientific Apparatus at South Kensington in 1876.
