The James Millikan University, Decatur, Ills., March 15, 1912. 

 The American Microscopical Society, in common with other similar societies 

 the world over, rejoices in the century of honorable and useful activity of The 

 Academy of Natural Sciences of Philadelphia, and extends to you its greetings 

 and congratulations on the completion of one hundred years of productive 

 effort. We confidently hope that the century upon which you are now entering

The American Museum of Natural History, New York. 



To the President and Board of Trustees of The Academy of Natural Sciences of 

 Philadelphia, Greeting: 



The President and Board of Trustees of The American Museum of Natural 

 History, through their delegate, Doctor Frederic A. Lucas, desire to tender to 

 The Academy of Natural Sciences of Philadelphia, their congratulations on the 

 completion of a century of active and earnest work. 



In this, the New World, few institutions can claim so long a career as yours, 

 few are so important, none can number among its members a more brilliant 

 galaxy of men of science than that which includes the names of Morton, Wistar, 

 Leidy, and Cope. 



May the progress of the Academy be ever upwards, may its career be as 

 prosperous, as vigorous in the future as in the past; may it ever stand, as it has 

 done for an hundred years, for all that is best in the cause of science in America. 



Henry Fairfield Osborn, 



President. 

 Archer M. Huntington, 



Secretary. 

 New York City, March the eighteenth, 1912.
