New Haven, June 3, 1885. 

 Dear President White : It would give me great pleasure to 

 comply with your invitation to take part in the Agassiz Memorial 

 Exercises at your University, but it is my misfortune to be unable 

 even to be present. Agassiz of all men of Science is the one I 

 most like to honor, both for what he was, and what he did for 

 American Science. My heart went out to him with strong affec- 

 tion; and I rejoice that your institution will commemorate his con- 

 nection with it and his great service to Science in a memorial tab- 

 let. Thanking you for your invitation, I remain 



Sincerely yours, 



James D. Dana. 

 Hon. Andrew D. White, Presidefit of Cornell University.

 President A. D. White. 



Dear Sir: In reply to your kind invitation to be present at the 

 ceremony of the 17th inst, in memory of L. Agassiz, and even to 

 make some remarks, I regret to say that for several years I have 

 been an invalid. I never leave Cambridge, and it is impossible for 

 me to attend any public ceremony, even the regular meetings of 

 the American Academy of Sciences at Boston. 



I am happy to learn that Cornell University is the first public in- 

 stitution to do justice to and honor him, who has done more for 

 zoology and the glacial theory in America, than any other scholar. 



I am the last survivor of those who came to the United States 

 with him or on account of him (except Lesquereux, who, however, 

 did not arrive until several months after our return from the ex- 

 ploration of Lake Superior, during the summer of 1848). This 

 is enough to show the interest which I take in everything that can 

 recall my regretted and illustrious friend. 



Very respectfully yours, Jules Marcou. 



New York, June 4th, 1E85. 

 Dear Sir : Your kind invitation to attend the unveiling of a 

 tablet commemorating the services of the distinguished geologist 

 and zoologist Louis Agassiz, just received. I regret that the dis- 

 tance is so great as to preclude my attending, or at least of giving 

 a definite promise ; but permit me to express my appreciation of 

 the act you are about to perform. Certainly the great name you 

 are about to honor is one intimately associated with that of the Uni- 

 versity ; and while the influence of Agassiz extends to every Amer-
