1 PROCEEDINGS OP THE GEOLOGICAL SOCIETY. [vol. lxxix, 



Gosselet dont je m'honore d'avoir ete le disciple. La doctrine de 

 Constant Prevost est bien celle de Lyeil, celle des causes actuelles 

 par opposition a celle des causes mysterieuses et inconnues contre 

 laquelle il fallait alors lutter. Mais Constant Prevost en a tire 

 des consequences de synchronisine exagere que les etudes poste- 

 rieures n'ont pas confirmees. 



Pour les jeunes qui nous suivent, la lutte est ailleurs, elle est 

 dans la theorie de la structure des montagnes et dans la possibilite 

 de deplacement des masses minerales ; la encore il est probabl e 

 qu'il y a exageration dans les deux sens, et que nous ai*riverons, 

 sous l'egide de Lyell, a des conceptions definitives basees sur des 

 constatations decisives. Merci, mes chers confreres, grand merci. 



Award of the Bigsby Medal. 



In banding the Bigsby Medal, awarded to Mr. Edward 

 Battersby Bailey, M.C., to Mr. C W. Lampltjgh, F.E.S., 

 for transmission to the recipient, the President addressed him 

 as follows : — - 



Mr. Lamplugh, — 



As a fellow- graduate of Mr. Bailey's University, I may venture 

 to express the opinion that the work which he has done entitles 

 him to a very honourable place in the list of Cambridge men who 

 have added to academic distinction the greater distinction that is 

 earned by successful labour in the field. Introduced to Scottish 

 Geology by Dr. Peach, Mr. Bailey devoted himself mainly to the 

 problems of tectonics and petrogenesis. In collaboration with 

 C. T. Clough and H. B. Maufe, he greatly advanced our know- 

 ledge of the mechanism of plutonic intrusion by the study of the 

 cauldron-subsidence ^of Grlencoe. The Highlands of Scotland are 

 famous in literature and in geology : the misty atmosphere of the 

 glens is charged with memories which appeal to the imagination 

 of the poet, and the structure of the rocks has long tried the 

 ingenuity and temper of geologists. In 1910 Mr. Bailey enun- 

 ciated a theory of recumbent folds in explanation of the structure 

 of the Ballachulish district, "and recently summarized the results of 

 his researches in other regions in a masterly communication to this 

 Society. His investigations have provided a stimulus which cannot 

 fail to have far-reaching effects. As a soldier as well as a geologist,
