8. East Anglia. 



^ = 174 kilom. (1848-1871). £ 2 *=86 kilom. 

 (10 localities and 18 shocks.) 



This very stable area is bounded by the North Sea, from the 

 Wash to the estuary of the Thames, and cuts like a wedge into 

 the heart of England up to the Bristol Channel. 



9. North-eastern Scotland. 



This is an extremely stable area, only 11 shocks having been 

 recorded : they occurred in 5 localities. 



10. Shetland Isles. 



In these islands shocks are rarely felt, unless they be those trans- 

 mitted from Scotland or Norway. Nevertheless, 5 shocks proper 

 to the Shetlands have been recorded. 



England and Scotland. 



Together: &= 185 kilom. #*= 91 kilom. 



England alone : 4= 193kilom - S 2 =95 kilom. 



§ 2. India. (PL XXXI.) 



The study of earthquakes has never received due attention in 

 India, notwithstanding the colossal disasters which have wrought 

 havoc in Kashmir and Burma. We possess, however, a good seis- 

 mological series of records from Assam. Historical documents in 

 India regarding earthquakes are of very small value. Altogether 

 761 shocks have been recorded from 136 localities spread over 

 13 regions. 



1. Upper Panjdb and Kashmir. 



S=±l kilom. (1885-1886). £ 2 =20 kilom. 

 (7 localities and 48 shocks.) 



The real boundaries of this area are just as much a matter of 

 dispute as the value of its ' historical seismicity.' Undoubtedly its 

 instability is great — as may be inferred from the catastrophes 

 which have befallen Kashmir and the frequent recurrence of earth- 

 quakes in the Upper Panjab. 



2. Assam. (Fig. 2, p. 657.) 



#,=114 kilom. (1839-1849). S 2 =34 kilom. (1874-1880). 

 (21 localities and 228 shocks.) 



This extremely unstable region has been very well studied from 

 the seismic point of view. It is bounded by the Brahmaputra 

 fromKarhharbari to Sudyah, and by a conventional line which
