SEISMIC PHENOMENA IN THE BRITISH EMPIKE. [Nov. 1 89 6, 



12. British Guiana. (Fig. 11.) 



The Guianas are generally stable, and the few shocks felt there 

 come from the Parian Gulf or the 

 West Indies. Fig. 11.

The Falkland Isles are certainly 

 extremely stable. British Borneo 

 and British New Guinea are pro- 

 bably stable too. On the other 

 hand, the converse proposition 

 would appear applicable to the 

 Fiji and the Chatham Groups. 

 Labuan is apparently stable. 



In conclusion the author con- 

 siders it highly desirable that 

 English observers, and meteoro- 

 logists in particular, disseminated 

 in all these colonies should care- 

 fully note all the shocks that occur. 

 The preceding pages have shown 

 how many parts of this vast empire 

 are comparatively unknown from 

 the seismic point of view.

Discussion. 



Sir Archibald Geikie referred 

 to the published work of the 

 Author in^ seismology and the laborious nature of the investi- 

 gations which he had summarized in the present paper. His idea 

 of ' seismicity ' was an original one, and, besides being simple 

 and ingenious, seemed to offer a more satisfactory standard of 

 comparison than had previously been available. 



The speaker, in communicating this paper to the Society, referred to 

 the recent death of the Foreign Member of the Society, Prof. Daubre'e, 

 at whose^ request he had undertaken to bring M. Montessus de 

 Ballore's investigations before the geological public in this country. 



Prof. John-ston-Lavis also spoke.
