NATURAL SCIENCES OP PHILADELPHIA. 421 



Besolved, That the Academy fully recognizes the fact that by 

 the death of one whose works and reputation shed lustre upon the 

 jjursuit of natural science, not only this country, but the intellec- 

 tual world, has sustained a loss which will not easily be replaced. 



Resolved, That, with the grief we would express for his loss as 

 one of the most eminent of modern naturalists, we cannot with- 

 hold the attestation of our gratitude for the course he took of 

 becoming a citizen of the United States, and for his untiring de- 

 votion to the development of the natural history of this continent, 

 thus having identified himself with American science, of which he 

 was a leading and most successful explorer. 



Resolved, That while his life and career were models to be imi- 

 tated by the student of nature, his genial temper, estimable quali- 

 ties and high honorable motives as a man endeared him to all who 

 came within his influence, and have left the most pleasurable rec- 

 ollections of his person and character. 



Resolved, That we deeply sympathize with those in whose im- 

 mediate behalf and for whose advancement his talents and energy 

 have been expended, and express tlie hope that the impulse he has 

 given to their labors may be continued, and that the interest he 

 aroused within the immediate circle of his efforts may not be lost, 

 but continue as a tribute to his worth and the perpetuation of his 

 fame. 



Resolved, That we fully appreciate the extent of the bereave- 

 ment which, under Providence, has befallen the family and friends 

 of Prof. Agassiz, and beg to express our heartfelt participation in 

 the sorrow experienced by them. 



The resolutions were adopted unanimously, and the President 

 of tlie Society was instructed to transmit a copy of them to the 

 widow of Prof Agassiz.
