On January 18th the great seismometro- 

 graph at the Osservatorio del Collegio 

 Romano at Eome registered five complete 

 pulsations of slow period characteristic of 

 earthquakes originating at a great distance. 

 They commenced at 4h. 37m. 30s. p. m. 

 (Greenwich mean time), and lasted Im. 

 22s., giving an average duration of 10.4 

 seconds for each pulsation. On the same 

 day a severe earthquake was felt along tin- 

 east coast of Japan, and was i-ecorded at 

 Tokio at 3h. 48m. 24s. The distance be- 

 tween tliis place and Rome being about 

 9,.500 km., the pulsations must have traveled 

 with an average velocity of 3.2 km. per 

 second (see XatKre, vol. 1. pp. 4.")0— ")1: vol. 



li., p. 4(i2). At Nicolaiew and Charkow, 

 in the south of Russia, the horizontal pendu- 

 lums were disturbed foi- nearly an liour, 

 the epoch of maximum amplitude occurring 

 a few minutes earlier than at Roun-. —
