Award oe the Wollaston Medal. 



in handing the Wollaston Medal, awarded to Prof. Waldemar 

 Chkistofer Brogger, P.M.G.S., to His Excellency Benjamin Yogt, 

 Minister Plenipotentiary for the Kingdom of Norway, the President 

 addressed him as follows : — 



Your Excellency, — 



It is most fitting that the medal which bears the honoured name 

 of Wollaston, and was founded by that eminent and philosophical 

 mineralogist, should be awarded to Prof. Brogger, who is not only 

 an accomplished chemist and a skilful mineralogist, but a great 

 petrologist. If lie had published nothing but his work on these 

 subjects, he would stand in the first rank of living geologists. But 

 he has done far more. His researches on the Cambrian and Ordo- 

 vician rocks of his own country have proved him to be a brilliant 

 palaeontologist and stratigrapher. His detailed mapping and inter- 

 pretation of the structure of the Christiania area and his explana- 

 tion of the origin of the Christiania Fjord, have proved him to be a 

 tectonic geologist of the highest order. His re?3arches on the 

 differentiation of rock-magmas have made him one of our foremost 

 teachers of pedogenesis. He has conducted an exhaustive research 

 on the Glacial and post-Glacial changes in Southern ^Norway, and has 

 expressed his results so cogently that we seem to see with our own 

 •eves the ice-sheets retreating, the seas advancing and retiring, and 

 to feel the climate slowly changing during the deposition of the 

 ■clays and shell-gravels of your country. He has brought his work 

 on the strand-lines into touch with the ages of man, and has even 

 •endeavoured to express these later stages of geological time in terms 

 of years. Nor has his life-work been devoted to science alone ; he 

 has served his fellow-countrymen as a member of the National 

 Legislature and his colleagues as the Bector of his University. 



But it is not so much the quantity as the quality of Prof. 

 Brogger's work that constitutes his claim to the Wollaston Medal. 

 His scientific training has been so thorough, his insight so deep, and 

 his outlook so wide, that in every subject which he has touched his 

 work has become a mine of fact, a model of expression, an example 

 of close and accurate reasoning, and a revelation of new principles. 

 In an age of specialization he is a specialist, but a specialist in 

 almost every branch of his science. That it should have fallen to
