THE third number of vol. x. of the Bolletino of the Italian Seismological Society contains the first instalment of the earthquake record for 1903. This is now in charge of Dr. G. Agamennone, and follows the same lines as in previous volumes, except that it has been found impossible to continue the attempt to reproduce all the records of earthquakes registered in Italy. This change is a consequence of the great increase in the number of stations where instruments devoted to the new seismology have been set up, and the consequent impracticability of collecting in one periodical all the records of even the limited number of great world-shaking earthquakes. Italy will, therefore, be content with publishing its own records, and at most a few lines will indicate those earthquakes which have also been recorded out of Italy.
