560 Obituary — Miss Maude Seymour. 



While at Lawrence, Williston's most important work was his 

 investigation of the reptiles found in the Chalk of Kansas, and the 

 results were finally summarized in a well-illustrated volume of the 

 University Geological Survey of Kansas (vol. iv, Palaeontology, pt. i) 

 published in 1898. In his early years at Chicago he continued these 

 researches, and his valuable papers on Plesiosanrs and Pterodactyls 

 in the Publication of the Field Columbian Museum, No. 78 (1903), 

 may be specially mentioned. He also published a little semi-popular 

 volume on Water Reptiles (1914). During the last decade he 

 devoted attention chiefly to the Permian lleptiles from Texas and 

 Missouri, describing important collections which he acquired for the 

 University of Chicago. These form the subject both of numerous 

 papers and of a small well-illustrated volume on American Permian 

 Vertehrates, issued by the Chicago University Press in 1912. Many 

 of the papers not only describe the fossils, but also discuss the 

 bearing of the new facts on some of the most fundamental problems 

 of vertebrate morphology. A complete list of Williston's papers up 

 to date, prefaced by a beautiful portrait, was printed by 

 J. T. Hathaway at New Haven in 1911. 



Williston was an attractive personality and left many devoted 

 pupils, of whom some have already made important contributions to 

 the science of which he was so successful an exponent. a q "w 



MISS MAUDE SEYMOUR. 



Born 1887. Died November 6, 1918. 



Those Fellows of the Geological Society who have been 

 accustomed to use the Library during the last few years will hear 

 with much regret of the death of Miss Seymour, who was appointed 

 as an assistant in tlie Library on September 1, 1915. The valuable 

 ■experience gained during several years of training on the staff of the 

 lloyal Society's Catalogue of Scientific Papers gave her the advantage 

 of a special knowledge of the literature with which she had to deal. 

 She devoted herself to the work with marked ability, and her 

 unflagging zeal and amiability of disposition substantially relieved 

 the pressure of an exceptionally harassing period. During this time 

 she gained an intimate knowledge of the work involved in the 

 preparation of the Geological Literature ; and by her sudden and 

 untimely death the Geological Society has lost a valuable official 

 whom it will be difiicult to replace.
