Yol. 54.] ANNIVERSARY ADDRESS OF THE PRESIDENT. Iv 



If we take a hurried survey of Steenstrup's activity as an author, 

 we see at the first glance that it was spread over many fields 

 without intimate relationship, such as zoology (in part very 

 specially), geology, and archaeology, and even purely historical 

 work. But on a nearer view it will be seen that there is a leading 

 thought, on which, as on a thread, are strung together studies 

 seemingly devoid of ensemble. From biological researches there is 

 no far cry to geology, and thence the path leads easily on to 

 archaeology and to the nearly-related byways of history. Steen- 

 strup's broad mind knew no artificial boundaries between all these 

 sciences. 



Steenstrup undertook in 1839-40 a journey to Iceland, and on 

 his return became Reader at the Soro Academy, whence in 1845 he 

 was transferred to the University of Copenhagen as Professor of 

 Zoology, which post he retained till 1885. 



The Royal Academy of Sciences of Stockholm elected him a 

 Foreign Member in 1857, and our own Royal Society a Foreign 

 Member in 1863. At the Lund Jubilee Celebration in 1868 he 

 was called to the honorary degree of Doctor in Philosophy, and he 

 was elected Foreign Member of the Stockholm Geological Society 

 in 1874. 



Tiberius Cornelius Winkler, Curator of the Teyler Museum, 

 Haarlem, was elected a Foreign Correspondent of this Society in 

 the year 1874. He died on July 18th, 1897. 



Dr. Winkler was the author of many palaeontological papers : 

 among others, those on fossil chelonia, published in 1869, and on 

 fishes, crinoids, pterodactyls, and plesiosaurs, which appeared in the 

 'Archives du Musee Teyler,' 1869-1883, and in the Haarlem 

 Nat. Hist. Soc. Proc. 1861-1862. He also devoted considerable 

 attention to the newer deposits of the Netherlands. 



Oscar F. von Fraas, who died on November 22nd, 1897, was 

 elected a Foreign Correspondent of this Society only a few days 

 before his death. He had been in failing health for some time 

 previously. Dr. von Fraas was born at Lorch, in Wiirtemberg, on 

 January 17th, 1824. He received his education at the University 

 of Tubingen. While there he came under the influence of 

 Quenstedt, who inspired him with zeal in the study of geology and 

 palaeontology. He subsequently studied in Paris under d'Orbigny 

 and Elie de Eeaumont. In 1854 he was appointed Conservator of
