Reports and Proceedings — Geological Society of London. 187 



who have heard you lecture on your own work or on other geological subjects, 

 have been greatly impressed by your careful choice of matter, the charm of 

 your style, and the lucidity of your expression. Certainly this award is given 

 to one by whom ' ' Geology has been materially advanced ' ' . 



In presenting an Award from the Proceeds of the Barlow-Jameson 

 Fund to Mr. John Frederick Norman Green, M.A., the President 

 addressed him in the following words : — 



Mr. Green, — It is not often that it is given to a geologist to succeed in 

 producing conviction by a single paper, still less by his first contribution to 

 the science ; but such has been your good fortune in the paper published 

 by this Society on the rocks of St. Davids. The appropriateness of your 

 methods, your careful recognition of lithological horizons, the accuracy and 

 detailed minuteness of your mapping, even the careful selection of the most 

 conclusive spot for excavation, have engendered such confidence in the result, 

 that we may regard as solved one of the chief difficulties in a most difficult 

 region. The Council has made to you an award from the Barlow- Jameson 

 Fund " for the advancement of Geological Science ", in the assurance that you 

 will carry the same accuracy and delicacy of work into other fields. 



The President then proceeded to read his Anniversary Address, 

 giving first of all Obituary Notices of several Fellows deceased since 

 the last Annual Meeting, including Prebendary W. H. Egerton 

 (elected a Fellow in 1832); T. ft. Polwhele (el. 1858); Major- 

 General W. E. Warrand (el. 1859) ; Captain G. E. Shelley (el. 1862) ; 

 the Rev. E. B. Watson (el. 1864); Dr. Theodore Cooke (el. 1866); 

 Mr. C. Fox-Strangways (el. 1873); Mr. A. H. Stokes (el. 1874); 

 the Rev. G. F. Whidborne (el. 1876) ; .Mr. T. M. Heaphy (el. 1876) ; 

 and Mr. C. Bird (el. 1882). 



He then made reference to the chief event of the year in the 

 Society's affairs — the resolution not to continue to maintain the 

 Museum, but to offer its contents to a National Museum or Museums. 

 He pointed out that the unanimous acceptance, at the annual 

 meeting, of the Report of the Council was confirmatory of the 

 action of the special general meeting which had originally passed 

 the resolutions. 



The subject of the Address was the consideration of Geology 

 as Geographical Evolution. The main factors of the geographical 

 evolution of an area were considered to be the alternation of upward 

 and downward movement. Each geographical cycle, passing from 

 the period of maximum depression through uplift into terrestrial 

 conditions and then back again towards depression and submergence, 

 would be expressed in the geological record by a corresponding 

 set of deposits consisting of ' thalassic ', 'shoreward', 'terrestrial', 

 ' estuarine', and again 'thalassic' deposits following each other in this 

 order. Each of these phases was considered in some detail, and 

 attention was drawn to difficulties in interpretation and correlation, 

 and to the principles according to whiclrthe depositional phenomena 

 should be translated into terms of geography. 



Despite the fact that several cycles of geography and deposition had 

 swept over Britain, there had been comparatively little repetition 

 of phase in the deposits, and two or three examples were taken to 

 illustrate cases of correspondence and non-correspondence of deposits 

 formed during similar stages in the succeeding cycles. The careful
