be filled with enthusiasm, of whom were Dr. Emmons, Dr. Beck, 

 Prof. Timothy Conrad, Dr. Locke, of Cincinnati, and many 

 others. On one occasion, while engaged on the United States 

 Coast Survey, Dr. Locke brought all his paraphernalia of work 

 and his assistants, pitching his tents in a field on the Vanuxem 

 farm near the house ; there he remained for some weeks, con- 

 tinuing his work, at the same time availing himself of the op- 

 portunity of study in and examination of the cabinet, making 

 numerous casts of the specimens, especially the rare fossils. 



After his death, Prof. Vanuxem's collection was purchased 

 by W. M. Stewart, President of Masonic College at Clarksville, 

 Tenn. It was reported that during the civil war the collection 

 was dissipated and destroyed, but this rumour could not have 

 been wholly true, for part if not all of the specimens are still 

 there. In May, 1892, one of Prof. Vanuxem's daughters was 

 applied to by a geologist for information as to the whereabouts 

 of this collection, as it contained, he said, the only known 

 specimen of a certain South Carolina fossil, which he very much 

 desired to examine. 



Prof. Vanuxem was a member of and assisted in the organ- 

 ization and establishment of the Philadelphia Academy of Nat- 

 ural Sciences and other scientific associations. 



" It was the habit of those connected with the New York 

 survey to meet at Albany at the end of each field season, for 

 the purpose of comparing observations and becoming ac- 

 quainted with each other. In the autumn of 1838 Prof. Van- 

 uxem suggested that an invitation be extended to the geolo- 

 gists of Pennsylvania and Virginia for the purpose of devising 

 and adopting a geological nomenclature that might be accept- 

 able to all those who were then engaged in the State surveys, 

 and thus become the nomenclature of American geology. This 

 meeting was finally held in 1840, and then the Association of 

 American Geologists was organized, which is now succeeded 

 by the American Association for the Advancement of Science." 



Some few years after the close of the New York survey, 

 Prof. Vanuxem was solicited by Prof. Henry, of the Smithsoni- 

 an Institution, at Washington, to become his associate in charge 

 of that institution. Although it would have been a work in 

 many ways congenial, the offer was declined, for various rea- 

 sons that he deemed good ones.
