3. Additional Notice of the occurrence o/ Volcanic Bombs in 

 Australasia. By the Rev. W. B. Clarke, A.M., F.G.S. 



[Abstract.] 



The author sent in 1855 a notice of the occurrence of Volcanic 

 Bombs in the gold-bearing alluvium of New South Wales * ; and in 

 this communication adds Victoria and Tasmania as countries in which 

 these obsidian-bombs have been found in the alluvial drift. 



One specimen was found by Mr. Milligan, Secretary of the Royal 

 Society of Van Diemen's Land, on the Supply Rivulet, Spring Bay, 

 River Tamar, in Tasmania, about twenty miles from Bass's Strait ; 

 the other specimen (like a bung in shape, an inch high and ly\ inch 

 thick at the upper part) was found near the River Wannon in the 

 district of Portland Bay. 



4. Notice of the occurrence o/" Metalliferous Ores and of Qokl. 

 in SiAM. By H. J. Moyle, Esq., and C. B. Hillier, Esq., 

 H.M. Consul at Bangkok. 



[Forwarded from the Foreign Office by order of Lord Clarendon.] 



(Abstract.) 



Mr. Moyle states that in the hilly districts extending north and 

 south, in lat. 15° 25', near the River Chaw-Phya (Meinam) in Siam, 

 he has discovered several apparently valuable veins of copper-ore, 

 principally in grauwacke, and that he has applied for and obtained 

 from the Siamese government authority to work them. He also 

 refers to his discovery of ores of lead and silver, with enormous beds 

 of magnetic and specular iron-ores in the same district ; and de- 

 scribes the country to the north as consisting of carboniferous lime- 

 stone, with indications of coal. 



Mr. Moyle states that the numerous rivers and canals afford great 

 facilities for the transport of the minerals from the hills ; and he 

 believes that Siam will rival any country in the East in the richness 

 of its mineral productions. 



Mr. Hillier mentions a report that beds of coal have been disco- 

 vered near the sea in the district of Chantabun on the eastern coast 

 of the Gulf of Siam. 



Note. — A small box of ores, chiefly cupriferous, with a specimen 

 of corundum, accompanied this communication from the Foreign 

 Office ; but these were not sufficient to decide the question of the 

 value of the ores. — Edit.
