﻿Vol. 64.] ANNIVERSARY ADDRESS OF THE PRESIDENT. ciii 



colleague H. B. Medlicott was in like manner loyally given to the 

 Indian service, but he communicated to the Society one paper, for 

 the writing of which his long Indian experience specially qualified 

 him — a comparison of the structure of the Alps and Himalayas.^ 



The West Indies have provided material for numerous communi- 

 cations to the Society, from the time of those that were published 

 in the Transactions down to the present day. Specially deserving 

 of mention are those of Mr. Jukes-Browne and Prof. J. B. Harrison 

 on Barbados and Trinidad,^ of P. Martin Duncan on the fossil corals 

 of the West Indies,^ and of Prof. Gregory on the paleeontology and 

 physical geology of the region.*^ The most recent accounts received 

 by us of the geology of this archipelago are the notices of a number 

 of the islands supplied by Prof. J. W. Spencer.^ 



Perhaps the most notable paper on South American geology 

 published by the Society is that by David Forbes, which appeared in 

 the Quarterly Journal for 1861. It gave an account of the geology 

 of Bolivia and Southern Peru, with a map of the region and sections 

 across the Andes, showing the fresh contributions which he had 

 made to our knowledge. Charles Darwin's important observations 

 on South America were published elsewhere, but he communicated 

 to the Society his well-known paper on the Falkland Islands, which 

 appeared in the volume of the Quarterly Journal for 1846.^ The 

 same volume contains his account of the fine dust which falls on 

 vessels in the Atlantic Ocean. 



Various papers connected with the geology of the Arctic regions 

 have from time to time appeared in our Journal. Of especial 

 consequence are those descriptive of fossils brought home by explorers, 

 for they have thrown light on the extension of Palaeozoic, Mesozoic, 

 and Tertiary formations into high latitudes. Some of the most 

 valuable of these communications have been made within the last 

 ten years, particularly those by Dr. Teall, Mr. E. T. Newton, and

^ The latest geologist who has visited these islands, Dr. J. G. Andersson, 

 now Director of the Geological Survey of Sweden, confirms the excellence of 

 Darwin's account of their geology. He has named after the great naturalist 

 the large 'stone-river' which Darwin described, and has furnished a map and 

 panorama of this remarkable feature. See ' Schwedische Siid-Polar-Expedition, 

 1901-1903' Tol. iii, pt. 2 (1907).
