 and counsel they have so generously extended in furthering the 

 objects of the expedition.

NECROLOGY. 



ORVILLE HITCHCOCK PLATT. 



It is with a keen personal regret that I have to record the death 

 on April 22, 1905, of Senator Orville H. Piatt, of Connecticut, who 

 for six years had served on the Board of Regents, and who at all 

 times took much personal interest in the welfare of the Institution. 



Senator Piatt was born in Washington. Conn., July 19, 1827. 

 After an academic education he undertook the study of law at Litch- 

 field. He was admitted to the bar in 1849, and practiced at Meriden. 

 He became secretary of state of Connecticut in 1857, In 1861-62 

 he was a State senator; later he served as a member of the State 

 house of representatives and as speaker of that body. From 1879 

 until the time of his death he w^as United States Senator from his 

 native State, and his public life belongs to his country. I shall not 

 add here my poor testimony to that of the history which will record 

 his contribution to the national good. He was a man honored by 

 all and best loved by those who best knew him. 



Respectfully submitted. 



S. P. Langley, 

 Secretary of the Smithsonian Institution.
