SPENCER FULLERTON BAIRD 281 



American science will be better able than are we to estimate justly 

 the value of the contributions to scientific literature which are 

 enumerated in the biography; but no one not living in the present, 

 can form an accurate idea of the personal influence of a leader 

 upon his associates, and upon the progress of thought in his special 

 department, nor can such an influence as this well be set down in 

 words. This influence is apparently due not only to extraordinary 

 skill in organization, to great power of application and concentra- 

 tion of thought constantly applied, and to a philosophical and 

 comprehensive mind, but to an entire and self-sacrificing devotion 

 to the interests of his own work and that of others."
