The following Address was adopted: 



To His Excellency 



WooDROW Wilson, 



Sir: The American Philosophical Society extends its cordial congratu- 

 lations to you, as one of its fellow members, upon your accession to the 

 Presidency of the United States. You carry into public life the ideals of 

 the scholar and you will show in the new world, as has been proved so often 

 in the old, that scientific training in the best and broadest sense of the term, 

 is a help to the practical statesman. Your studies in history and political 

 science will illuminate your task of giving to the Nation a wise and strong 

 government. 



It was Montesquieu, the good genius of the makers of our National 

 Constitution, who said that for a safe voyage of the Ship of State the spirit 

 of the laws should serve as compass and history should be the chart. This 

 Society confidently believes that you have at your command this compass 

 and this chart; that with your firm hand at the helm the Ship of State will 

 safely ride the seas, and that, like those of your distinguished predecessors 

 in the Presidency, who were its members, you will help to make the future 

 history of the Nation worthy of its past. 



Seven times since the founding of the Republic the American Philo- 

 sophical Society has had cause for congratulation in the selection of one of 

 its members as President of the United States. Washington, Adams, Jef- 

 ferson, Madison, the second Adams, Buchanan and Grant were all honored 

 names upon its Roll before the popular vote inscribed them in the list of 

 American Presidents. To you, the eighth in turn of its members to enter 

 upon this high office, this Society extends its warmest greeting. 



Given under the Seal and in the name of The American Philosophical 

 Society held at Philadelphia for Promoting Useful Knowledge, this seventh 

 day of March, 1913. 



Stated Meeting April 4, 191 3. 

 William W. Keen, M.D., LL.D., President, in the Chair.
