2IO NATURAL SCIENCE. September. 1896 



he introduced to science many well-known geologists and palaeontolo- 

 gists now working in Germany. He was also appointed a director of 

 the Geological Survey of Prussia, and the Thuringian States, and 

 became the head of the Museum of Natural History in Berlin. Along 

 with Von Buch, Humboldt, and other famous men of the past, he 

 was one of the founders of the German Geological Society ; and these 

 early associations it may have been that made him a laudator temporis 

 acti, and that set his face against innovations. His last visit to this 

 country was to the Geological Congress of 1888, he was elected a 

 Foreign Member of the Geological Society of London in 1876, and one 

 of his latest interests was the assistance he gave towards the compila- 

 tion of the geological map of Europe now in course of publication. 



Beyrich's death makes a widow of one well known in Germany 

 as a writer for children, under the name of Clementine Helm. 



JOHANN GEORG BORNEMANN. 

 Born 1831. Died July 5, i8g6. 



THIS geologist was born at Miihlhausen in 1831. In 1856 he went 

 for a long tour through Italy, Sardinia, and the neighbouring 

 islands, a journey which resulted in a series of papers on the geology 

 of those places, and by which he is best remembered. 



He was one of the enthusiastic band of German palaeontologists 

 who worked at the Foraminifera between 1850 and i860, and his 

 papers on these fossils from the Lias of Gottingen, the Septarienthon 

 of Hermsdorf, and the Tertiaries of Magdeburg contain much 

 valuable information. He died at Eisenach, where his son Ludwig 

 Georg, himself a well-known geologist and a distinguished col- 

 laborator in his father's work, resides. C. D. S. 



We have also to record the deaths of: Otto Lilienthal, who 

 had demonstrated the possibility of sailing through the air, at one 

 bound, some 500 metres with his first-constructed apparatus, while 

 with his second machine, with its wing-like terminations moved 

 vertically by means of a small compressed carbonic-acid gas motor, 

 he had succeeded in sustaining and prolonging his sail for a longer 

 distance by flapping these " wings " ; J. Lloyd, compiler of a work 

 on the flora of western France, on May 10, in Nantes, aged 87 ; 

 Dr. F. VoN Herder, botanist, on June 7, at Griinstadt ; Dr. Kanitz, 

 professor of botany in Klausenberg University ; on March 26, 

 in Yokohama, the conchologist B. Schmacker, aged 44 ; on June 10, 

 Count E. Harrach, an enthusiastic zoologist ; A. Gobanz, an 

 authority on the geology and mineralogy of Greece, aged 70 ; on 

 April 17, A. v. Sommerfeld, a lepidopterist, in Brazil, aged 30; 

 and A. Salle, a zoologist and explorer, especially known for his 

 conchyliological and entomological researches in Central America.
