MUSEUM OF COMPARATIVE ZOOLOGY. 35 



standing that they are used as mineral specimens, and any criticism on the organisms 

 should be based on the complete core at Sydney or on the core and sections to be 

 deposited in the British Museum. Of course from what you kindly told me when 

 you saw the specimens I was able to give this assurance, and I trust that they will 

 prove useful for comparison with your upraised reefs. 



Believe me to remain, very truly yours, 



John W. Judd.

Washington, D. C. , October 6, 1902. 



My dear Sir, — You may possibly recall a conversation which we had at a 

 dinner given to the National Academy of Sciences, I think on the event of your in- 

 auguration as President. This conversation related to a portrait of your father, 

 which is in my possession, and which I then expressed a desire to present to the 

 Museum of which he was the illustrious founder. 



As I am about to break up at the Observatory, I am now ready to deliver the 

 picture, and will send it boxed to the address as given by you on notification from 

 you that it will be agreeable to you to receive it. The picture was, to the best of 

 my belief, painted by Ames, of Boston, and represents Professor Agassiz at just 

 about the time when the first building of the Museum was under construction on 

 Divinity Avenue. It would therefore be particularly appropriate for the Museum. 



The only conditions which I attach to this gift are that it shall be considered as a 

 donation to the Museum and not to an individual; 2d, that it shall be held in per- 

 petuity and constantly exhibited in the Museum ; 3d, that the Museum shall agree 

 that it will at no time dispose of this picture, either by sale or gift ; 4th, that if at 

 any time it should decide or desire so to dispose of the picture, that it shall then 

 revert to the heirs or assigns of the donor. 



Trusting to hear from you at an early date, I am, my dear sir, 



Very respectfully and sincerely yours, 



C. H. Davis, 



Captain U. S. N. 

 Prof. Alexander Agassiz, Cambridge, Mass.
