Hi PROCEEDINGS OP THE GEOLOGICAL SOCIETY. [May 1 895, 



error on trie right side, and, whenever Cotteau determined European 

 species in other continents, his conclusions have been implicitly 

 accepted. 



M. Cotteau was elected a Foreign Correspondent of this Society 

 in 1874, a Foreign Member in 1891, and a Correspondent of "the 

 Academy of Sciences of Paris in 1887. He has bequeathed his fine 

 collection of Echinoids to the Museum d'Histoire Naturelle in Paris. 

 He was working almost to the end, for copies of five papers published 

 last year were received by the Society shortly after his death, 

 addressed by himself, and left ready for the post. He passed away 

 on the 10th August, 1 894, in his house in Paris, in the 67th year of 

 his age.— [J. W. G.] 



George Huntington Williams was born at Utica, N". Y., in 1856. 

 He graduated from the Utica Free Academy, entered Amherst 

 College in 1874, and took his first degree in 1878. While at 

 college he caught his enthusiasm for geology from his Professor, 

 B. X. Emerson, and spent a year in graduate studies at Amherst. 

 He then went to Berlin, where he perfected his knowledge of 

 German, and to Heidelberg, where he became a devoted pupil of 

 Bosenbusch, and took the Ph.D. degree in 1882. In the following 

 year he became a Fellow in the Johns Hopkins University, where he 

 was appointed Professor of Inorganic Geology in 1885, which position 

 he still held at the time of his death, which took place on July 12th, 

 1894. Prof. Williams was elected a Foreign Correspondent of the 

 Geological Society in 1892. 



Petrography and crystallography were the special departments of 

 geology which he cultivated, and his text-book on crystallography 

 is a lucid exposition of the methods of research in this line. At the 

 time of his death he was at work on a treatise on the ' Microscopic 

 Structure of American Crystalline Bocks.' He was one of the best 

 authorities on these subjects in America, and served as one of the 

 judges of award in the department of Mineralogy at the Columbian 

 Exposition. His untiring devotion last summer at Chicago to the 

 duties thus put upon him may, it is feared, have laid the foundation 

 of the disease which sapped his otherwise vigorous constitution. 

 Prof. WiUiams was an attractive teacher, and had a peculiarly 

 pleasing manner in both private conversation and public address. 

 The animated and clear descriptions which he gave of even the most 

 technical subjects went far to interest his hearers in any topic 

 that he chose to speak upon. His broad education, attractive
