xcii PROCEEDINGS OF THE CENTENARY MEETING. 



Imp. Moskovskij Universitet. 



Moscow, February 26, 1912. 

 No. 756. 



To The Academy of Natural Sciences of Philadelphia, 

 Gentlemen : 



The oldest of the Russian universities, the Imperial University of Moscow, 

 has directed us, in its behalf, to offer to the oldest of American learned insti- 

 tutions for natural sciences, The Academy of Natural Sciences of Philadelphia, 

 most sincere and hearty congratulations on the auspicious occasion of the 

 Hundredth Anniversary of its scientific birth. In the past hundred years the 

 professors, lecturers, and assistants of our University have followed with great 

 interest the valuable records of the old Journal and the Proceedings, con- 

 taining so many memoirs important to natural sciences not only in America, 

 but in all the civilised world. Your Proceedings are known and valued 

 wherever natural sciences are cultivated. 



Much regret is felt that no member of this University can be present as a 

 Delegate at your celebration, to express in terms befitting the occasion the 

 sentiments of high esteem constantly held by us, and the ardent wishes 

 we have for your success in future in every undertaking. We most cordially 

 express confident hope that the future of The Academy of Natural Sciences of 

 Philadelphia will be as brilliant as its past.
