President's Address. 311 



For many years Gegenbaur was professor in Jena, where he was 

 the close friend and associate of Ernst Haeckel, but in 1875 he 

 accepted the invitation to the Chair of Anatomy in Heidelberg, and 

 in view of the increased importance of his duties as a teacher of 

 medical students, and therefore of human anatomy, though still con- 

 tinuing his researches on vertebrate morphology, he produced a 

 large treatise on that subject, which has ran through two editions. 

 In this work he made the first attempt to bring, as far as possible, 

 the nomenclature and treatment of human anatomy into thorough 

 agreement with that of comparative anatomy, and to a very large 

 extent the changes introduced by him have influenced the teaching 

 of human anatomy throughout Europe and America. 



There is probably no comparative anatomist or embryologist in 

 any responsible position at the present day who would not agree in 

 assigning to Gegenbaur the very first place in his science as the 

 greatest master and teacher who is still living amongst us. He is 

 not only watching in his old age the developments of his own early 

 teachings and the successful labours of his very numerous disciples, 

 but is still exhibiting his own extraordinary industry in research, his 

 keenness of intellectual vision, and his unrivalled knowledge and 

 critical judgment. 



ROYAL MEDAL. 

 Sir Archibald GeiJcie, F.R.S. 



One of the Royal Medals is conferred on Sir Archibald Geikie, on 

 the ground that of all British geologists he is the most distinguished, 

 not only as regards the number and the importance of the geological 

 papers which he has published as an original investigator, but as one 

 whose educational works on geology have had a most material 

 influence upon the advancement of scientific knowledge. 



His original papers range over many of the main branches of 

 geological science. His memoir upon the ' Glacial Drift of Scotland ' 

 (1863) is one of the classics in British geology. His work on the 

 ' Scenery of Scotland, viewed in connection with the Physical 

 Geology ' (1865) was the first successful attempt made to explain 

 the scenery of that country upon scientific principles, and is still 

 without a rival. His papers on the " Old Red Sandstone of Western 

 Europe " (1878-79) gave for the first time a clear and convincing 

 picture of the great lake period of British geology, founded upon 

 personal observation in the field. 



His many original contributions to the Volcanic History of the 

 British Isles form a succession of connected papers, crowded with 

 important observations and discoveries, and brilliant and fertile 

 generalizations respecting the abundant relics of former volcanic
