Vol. 60.] ANNIVERSARY MEETING WOLLA3TON MEDAL. xll 



Award of the Wollabton Medal. 



In handing the Wollaston Medal, awarded to Prof. Albert Hem, 

 of Zurich, to Mr. J. J. H. Teall, M.A., E.R.S., for transmission to 

 the recipient, the Chairman addressed him as follows : — 



Mr. Teall, — 



The Council of the Geological Society of London have awarded 

 to Prof. Heim the highest honour which they have to bestow — 

 the Wollaston Medal, in recognition of the value of his researches 

 concerning the mineral structure of the Earth, and more especially 

 of his contributions towards the elucidation of the structure of 

 mountain-masses, as illustrated in the chain of the Alps. In 

 his great monograph, the ' Mechanismus der Gebirgsbildung,* he 

 traced with remarkable skill the influence of plication in the 

 terrestrial crust, following this influence step by step from the 

 distortion and fracture of organic remains in hand-specimens up 

 to the most gigantic foldings which have comprised a vast mountain- 

 chain in their embrace. His researches, however, have not been 

 confined to the internal structure of the Alps. He has devoted 

 himself with not less enthusiasm and success to the study of their 

 glaciers and their landslips. Gifted with no ordinary artistic power, 

 he has been able to enrich geological science with a valuable series 

 of landscape-drawings and sections, in which the intimate relations 

 of geology and topography are admirably delineated. His latest 

 achievement in this department is a large model of the massif of 

 the Hohe Siintis, which was exhibited at the recent meeting of the 

 International Geological Congress in Vienna. It was admitted by the 

 assembled geologists to be probably the most accurate and beautiful 

 model of a mountain-group that had ever been constructed. We 

 may judge of the labour and enthusiasm spent on it from the 

 fact that, besides climbing to every crest of that rugged tract, 

 Prof. Heim made many ascents in a balloon, so as to obtain 

 detailed and comprehensive bird's-eye views of the whole region 

 which he wished to depict. In asking you to be so good as to 

 transmit to him this Medal, I would request you to convey with 

 it an expression of our warmest wishes for a long continuance 

 of the mental and bodily activity which he has so unsparingly 

 devoted to the interests of our science.
