of Geneva, the Council of Swiss States, and the National Council; 

 and he exerted a strong personal influence in political affairs. 



Professor Yogt labored earnestly to promote the establishment 

 of marine zoological laboratories, as well as of smaller stations, and 

 sought to enlist the co-operation in the scheme of friends in high 

 places in different countries. His efforts in behalf of this cause con- 

 tinued through forty years, his first letter on the subject having 

 been written in 1855, and his last in 1894. 



The theory suggested in Darwin's Origin of Species fell in well 

 with Professor Yogt's views, as they may be found expressed in 

 citations from his writings as far back as the Embryology of the 

 Salmons, in 1842. Yet, as M. Quatrefages has shown in his Emules 

 de Darwin, he did not agree with that author in all points. Diver- 

 gences between the two are shown in Yogt's study of the Archceop- 

 teryx and in articles published in French and German reviews and 

 issued afterward in separate form. 



In May, 1861, Professor Yogt went, on the invitation of Dr. 

 Berna, of Frankfort, upon a voyage to the northern seas in the brig 

 Joachim Heinrich. Besides these two, Gressley, the erratic geolo- 

 gist, Hasselhorst, the painter, and Alexander Herzen, the younger, 

 were of the party. Having visited the North Cape, they proceeded 

 to Jan Mayen, an island whose ice-bound coasts had baffled many a 

 sailor and explorers of high rank, and which was still nearly un- 

 known. They effected a landing and examined the whole rock. 

 They then went to Iceland, where the capital was decorated in their 

 honor, and started for home on the 15th of September. Professor 

 Yogt's book descriptive of this voyage was published in October, 

 1862. 



The special characteristic of the Vorlesungen ilber den Menschen 

 Lectures on Man 1862-63, which was translated into sev- 

 eral languages, was its presentation for the first time in the con- 

 crete, and compactly, of the fundamental data of anthropology and 

 its insistence upon the anatomical relations of man with the lower 

 animals. It played a prominent part in the controversies of the 

 next ten years over materialism. A less serious work was the trans- 

 lation of Brillat Savarin's Physiology of Taste, in recognition of 

 which the translator was made honorary president of the Society of 

 Cooks of Munich. The discoveries of the flint implements, the 

 relics of man in caves, and the lake dwellings were the subject of 

 several memoirs by Professor Yogt, and he projected a complete 

 work upon them, but was never able to prepare it. His last paper 

 on the subject was one respecting the bones of the Pithecanthropus 

 erectus, which was published in a Frankfort journal two months pre- 

 vious to his death.
