10 CARNEGIE INSTITUTION OF WASHINGTON. 



sarily to an excess of expectations vastly greater than could be 

 realized, has had not only to keep free from numerous untoward 

 alliances but also to avoid numerous legal complications. In this 

 branch of the Institution's work the conserving wisdom of Mr. 

 Cadwalader has been invaluable. His readiness of comprehen- 

 sion of the essentials of a question and the clearness and justness 

 of his recommendations made him a model counsellor for a 

 research establishment. Impatient with pretense and with 

 circumlocution, he got quickly at the gist of any problems 

 submitted to him and he arrived equally quickly at practicable 

 and honorable solutions for them. 



One of the most noteworthy features of the advancing civiliza- 

 tion of our times is seen in the increasing numbers of men and 

 women willing to devote their fortunes, their superior learning, 

 or their gratuitous labors in the promotion of undertakings for 

 the common w^eal. In this sort of activity Mr. Cadwalader was 

 a conspicuous figure; and no one could have given more freely 

 of his time and talents than he. His aid to the Institution 

 was a constant source of encouragement. It was occasionally 

 essential to appeal to his knowledge of human nature as 

 well as frequently essential to draw on his knowledge of legal 

 affairs. Busily occupied as he was with professional engage- 

 ments, he was ever ready to suspend them in order to aid the 

 Institution. Even during his last illness, less than a month 

 before his death, he insisted that he would gladly give m.e counsel 

 at his bedside concerning a matter of pressing importance that 

 had just then arisen. His fidelity to the Institution, extending 

 thus near to the end of his life, was one of many manifestations 

 of a fine idealism to which he often gave expression in conver- 

 sation and in correspondence, to the effect that the Founder and 

 the Trustees had entered into a copartnership whose unwTitten 

 obligations must be strictly observed. 



It is fitting to record here also the death of an associate of 

 the Institution distinguished for preeminence in the domain of 

 celestial mechanics, namely, George William Hill, who died at his 

 home in West Nyack, New York, April 16, 1914.* Dr. Hill's 



*Hill was born in New York City on March 3, 1838. A more extended account of his life and 

 work has been published in the Astronomical Journal, No. 668, June 5, 1914.
