Carboniferons Limestones, and this work apparently introduced 

 him to the study of the Belgian caves, the human relics con- 

 tained in them, the classification of the periods of human art^. 

 and, later, to the study of the Quaternary deposits of his country. 

 On these subjects he published a work dealing with the Stone- 

 Age in the vicinity of Dinant-sur-Meuse. He also made important 

 contributions to our knowledge of the Belgian Devonian, and was 

 associated with M. Mourlon in the preparation of a general map 

 of the country. He wrote an essay on this map, and also on the 

 Belgian part of the International Congress Map of Europe. In. 

 1887, he wrote on the living and post-Pliocene mollusca of the 

 Congo. As Director of the lloyal Museum, M. Dupont was chiefly 

 interested in the skeletons of Iguanodon, mainly from Bernissarty. 

 which were mounted under his superintendence. Of these he wrote- 

 an account as a guide to the Museum Collection. 



Chaeles Abiathar White, elected a Poreign Correspondent in 

 1893 and a Foreign Member in 1899, was born on January 26th,. 

 1826, and died on June 29th, 1910, in his eighty-fifth year. Hi^ 

 earliest published work dates from 1861, and in the two following- 

 years he assisted James Hall in palaeontological work for New 

 York State. He was appointed Stale Geologist of Iowa in 1866,. 

 and conducted that Survey until 1870, being responsible for the 

 issue of an important series of Beports. His work at this period 

 was chiefly concerned with glacial deposits and with pal?eonto- 

 iogical questions. In 1867 he was appointed Professor of Natural 

 History in the Iowa State University, and continued to hold this 

 post until 1873, when he passed to a similar position in Maine. 

 In the following year, he undertook the publication of the inver- 

 tebrate palaeontology of the Survey of the country West of the 

 Hundredth Meridian. He joined the United States Geological 

 Survey of the Territories in 1876, was appointed Curator of Palce^ 

 ontology in the U.S. National Museum in 1879, and Geologist on 

 the Geological Survey of the United States in 1882, a post that he 

 held for ten years, in the course of which he also executed pala3- 

 ontological work for the National Museum of Brazil. The degree 

 of LL.D. was conferred upon him by his old University of Iowa 

 in 1893. A long list of his papers is published in Bulletin 30 of 

 the United States National Museum ; and this shows that he wrote 

 on very many of the branches of geology, and in the course of his 

 work described a vast number of species of Invertebrata.
