his elegant mathematical solution of complex problems and the graphic 

 presentation of involved relationships in various kinds of diagrams. 



Numerous honors came to him, not only from his countrymen, but also 

 from men of science in all parts of the world. He was a member of the 

 Institute (Academy of Science), an officer of the Legion of Honor, and 

 an honorary member of the Eoyal Academy of Sciences of Prussia, the 

 Mineralogical Society of Great Britain, the Geological Society of Bel- 

 gium, the Eoyal Academy of Dublin, and the Geological Society of Lon- 

 don. In 1865 he was awarded the Laplace prize, and, in 1887, the 

 Viquesnel prize of the Geological Society of France; five years later he 

 was elected president of that organization. In 1894 he was made presi- 

 dent of the Mineralogical Society of France, and in 1904 he was chosen 

 to succeed Fouque as professor of the Natural History of Inorganic Sub- 

 stances at the College de France. He was elected a correspondent of 

 the Geological Society of America. in December, 1910. 



It is a pleasure to mention, finally, those qualities which won him the 

 respect and admiration of his associates. He was a man of singular dig- 

 nity and serenity, combined with a never-failing courtesy and a helpful 

 interest in the work of even the humblest students of geology. In the 

 midst of the many duties of his official work he gave freely of his time and 

 kindly advice to students of geology, mineralogy, and petrography in the 

 various educational institutions of Paris, although until 1904 his only 

 connection with them had been as director of a research laboratory for a 

 short time during the early eighties.
