1898] OBITUARIES 421 



" At last with the creeping on of old age and the effects of con- 

 tinued saturations and exposures, to which real field-workers are 

 subject but from which arm-chair critics and moneyed collectors for- 

 tunately escape, his throat and chest grew gradually worse. His last 

 effort was to try and write to Mr Benjamin Harrison, giving a new 

 argument in favour of Plateau Man." 



KARL LUDWIG FRIDOLIN VON SANDBERGER 



BoKN 22nd Nov. 1826 at Dillenburg, Nassau. Died at 

 WiJRZBUKG, April 11th, 1898. 



It is over half a century since this veteran geologist commenced 

 author. He is perhaps best known for the work written in colla- 

 boration with his brother Guido, " Die Versteinerungen des rheinischen 

 Schichten-systems in Nassau," which was published during the years 

 1850-56, and has ever remained the classical account of the geology 

 and palaeontology of that region. In consideration of this work the 

 authors received the Wollaston Fund from the Geological Society of 

 London in 1855. The next important work on which Dr Sandberger 

 engaged was an account of the shells of the Tertiary Basin of Mayence 

 (1863). The studies made in connection with this gave rise to a 

 general account of fossil land and fresh-water shells, wdiich was 

 issued in two volumes, 1870-75. Dr Sandberger studied many other 

 fossil Mollusca, as well as the structure of the Brachiopoda. In later 

 years, however, he turned his attention chiefly to mineralogy, and in 

 1882-85 published his " Researches on Mineral Veins." He also 

 made many contributions to the study of the microscopic struc- 

 ture of eruptive rocks. In 1849 Ericlolin Sandberger was made 

 curator of the Natural History Museum of Nassau, and in 1854 went 

 to the Karlsruhe Pol}'technic as Professor of Mineralogy and Geology. 

 Here he stayed till 1863, when he was called to Wiirzburg to fill the 

 chair of Mineralogy, to which Geology was then added for the first 

 time. This post, which carried with it the direction of the Mineral- 

 ogisches Institut, he held till a short time before his death. The 

 Geological Society of London elected him a foreign member in 1875, 

 and in the following year he received the Cothenius gold medal from 

 the Leopold-Caroline Academy. 



JULES MARCOU 



Born at Salins, French Jura, 20th April 1824. Died at 

 Cambridge, Mass., 17th April 1898. 



What interesting reminiscences Jules Marcou's would have been had 

 he published them ! A citizen of two hemispheres, writing with equal 

 facility and spirit in French and English, the pupil of Thurmann, the 

 friend of Agassiz, the explorer of the West, a historian of ancient 

 maps and a maker of new ones, a lover of truth at all hazards, a hater 

 of humbug, and a thorough-going fighter. Perhaps he has left a 

 manuscript somewhere. At any rate, he did the next best thing in 

 producing a life of Louis Agassiz, which both before and after pub- 

 lication stirred up a good deal of controversy. Above all things
