his mind and in the wide range of his acquisitions he was fitted 

 to be, as Dante has said of Aristotle, "the master of those who 

 know." 



And this power of his mind to assimilate knowledge of various 

 kinds naturally leads me to speak of his skill in imparting it. He 

 was a most successful educator. He had many other titles of 

 honor or office, but the title of Professor seemed to rank them 

 all, for everybody felt that he moved among men like one anointed 

 with the spirit and power of a great teacher. And he had philo- 

 sophical views of education, extending from its primary forms to 

 its highest culminations — from the discipline of the "doing 

 faculties" in childhood, to the discipline of the "thinking facul- 

 ties" in youth and manhood. No student of his left the Albany 

 Academy, in the earlier period of his connection with that 

 institution, without being thoroughly drilled in the useful art 

 of handling figures, for then and there he taught the rudimental 

 forms of arithmetic, not so much by theory as by practice. No 

 student of his left Princeton College without being thoroughly 

 drilled in the art of thinking, as applied to scientific problems, 

 for then and there he was called to indoctrinate his pupils in the 

 rationale as well as in the results of the inductive method. And 

 I will venture to add that no intelligent student of his at Prince- 

 ton ever failed, in after life, to recognize the useful place which 

 hypothesis holds in labors directed to the extension of science, 

 or failed to discriminate between a working hj'pothesis and a 

 perfected theory. 



Pausing for a moment at this stage in the analysis of Profes- 

 sor Henry's mental and moral traits, I cannot omit to portray the 

 effect produced on the observer by the happy combination under 

 which these traits were so grouped and confederated in his per- 

 son as to be mutual complements of each other. Far more sig- 

 nificant than any single quality of his mind, remarkable as some 

 of his qualities were, was the admirable equipoise which kept the 

 forces of his nature from all interference with the normal develop- 

 ment of an integral manhood. He was courtly in his manners, 

 but it was the courtliness which springs from " high thoughts 

 seated in a heart of courtesy," and had no trace of aflFectation or 

 artificiality ; he was fastidious in his literary and artistic tastes, 

 but he had none of that dilettantism which is "fine by defect 

 and delicately weak;" he was imbued with a simplicity of heart
