106 APPENDIX TO JOURNAL. 



in supporting, or in assisting to support, at such European universities 

 as tliej' 7nay consider most desirable, two American pupils, who may 

 evince decided talents in physics, and who may express a determination 

 to devote their lives to this work. My desire would be that each pupil 

 should spend four years at a German university — three of those years to 

 be devoted to the acquisition of knowledge, and the fourth to original 

 investigation. 



If, however, in the progress of science in the United States, it should 

 at any time appear to the said board that the end herein jiroposed 

 would be better subserved by granting aid to students, or for some 

 special researches in this country, the board is authorized to make the 

 appropriations from the income of tbe fund for such purposes. 



I further direct that vacancies which may occur in said board of 

 trustees, by death or otherwise, shall be tilled by the president of the 

 National Academy of Sciences. 



If in the course of any year the whole amount of the interest which 

 accrues from the fund be not expended in the manner before mentioned, 

 the surplus may be added to the principal, or may be expended in addi- 

 tion to the annual interest of another year. 



If at any time any organization shall be established, and money pro- 

 vided by other persons for the promotion of such original research as I 

 have in view, I authorize the said board of trustees to exercise their 

 discretion as to co operating in such work from the income of this fund. 



In witness whereof I have hereunto set my hand and seal this 7th oi 

 February, 1873, in the city of 'New York.
