Shortly before his death, in 1878, a number of personal friends 

 established a fund " as an expression of the donors' respect and 

 esteem for Professor Joseph Henry's personal virtues, their 

 sense of his life's great devotion to science with its results of im- 

 portant discoveries, and of his constant labors to increase and 

 diffuse knowledge and promote the welfare of mankind." This 

 fund, which amounted to $40,000, was deposited with a trust

 of the last survivor it should be delivered to the Academy " to 

 be thenceforward forever held in trust under the name and title of 

 the ' Joseph Henry Fund,' the principal to be forever held intact,

 National Academy of Sciences in its sole discretion to assist 

 meritorious investigators, especially in the direction of original 

 research."

 adviser of the Government.

 Professor Wm. B. Rogers was elected President. The term of 

 office under the constitution was six years, but Professor Rogers
