 Russia, Samoa, Porto Rico, Hawaii, Syria, Azores and Servia. 



The discussion of the mass of detailed figures thereby collected 

 shows it to be a specialist's work in the domain of geophysics, and to 

 be quite independent of the particular point of the earth's surface 

 where the earthquake was sensibly felt. It is a world problem of too 

 general a nature to find a place in these Memoirs. 



VI.-THE EARTHQUAKE SOUND. 

 No sound at all was recorded from the following localities : — 



(1) Afghanistan. 



(2) Assam. 



[N. B. — It is not absolutely certain that the shook was even felt by many in Assam. 

 Several records of a shock on the day of the earthquake acoompanied by a sound were 

 probably local in origin, or should be considered as aftershocks of the 1897 earthquake. 

 The same remarks probably apply to the sounds reported at Daloo Tea Estate, Cachar, 

 on the evening preceding and half an hour after the shock.] 



(3) Baluchistan. 



(4) Burma. 



(5) Madras. 



(6) Nepal. 



Of these 6 areas Burma and Madras did not feel the shock, with one 

 doubtful exception in the latter area, and it would be unreasonable 

 to expect the sound to have been heard there. From the other areas 

 only a few records were received, hence the negative evidence in their 

 case is not very strong, especially as regards Nepal and Afghanistan. 



In Bengal accounts from 122 places (which include many where the 

 shock was also not felt) record or mention no sound. Of the few 

 places whence a sound is recorded mention may be made* of Balasore 

 where it is described as being like " a railway train," Suri (Birbhum
