PROCEEDINGS OF THE CENTENARY MEETING

University of Virginia 





University of Virginia, March 12, 1912. 



The President and Faculty of the University of Virginia desire to present to 

 The Academy of Natural Sciences of Philadelphia their hearty congratulations 

 on the completion of a century of scientific activity and achievement. Founded 

 at a time when the study of nature in this country was followed by but few 

 students, and organized societies for the advancement of such study were in 

 existence at but two or three widely separated points, the Academy has held an 

 honorable place and has contributed largely to the results of scientific research in 

 America. May the second century of its existence be marked by as vigorous 

 and fruitful life as that which closes so auspiciously. 



Edwin A. Alderman, 



President.
