calculates that it will take about thirty years for the district to regain its 

 original stability. The records for the Kumamoto earthquake, which took 

 place in July 1889, show a like result, but with a rate of decrease 

 directly proportional to the intensity of, or the area shaken by, the primary 

 disturbance. 



One curious fact connected with the extinction of the Nagoya earth- 

 quake is that the district of greatest visible faalting, where valleys were 

 compressed and mountains were lowered, seems to have reached a fair 

 state of quiescence, while the most active settlement, or the district where 

 an extension of faulting is now taking place, is at the S.E. extremity of 

 the main line of original disturbance— a few miles N.E. from Nagoya in 

 Niwa-gun (N. lat. 35° 20', and E. long. 136° 50'). 



Not only would the publication of the catalogue here indicated furnish 

 material very much better than that which has been hitherto attainable 

 for the continuation of investigations like those made by Perrey, Mallet, 

 and other seismologists, but we should have materials for investigations 

 which would be entirely new.
