3G2 MEMORIAL OF JOSEPH HENRY. 



As a lecturer and instructor, lie was always most successful. 

 Free from all self-consciousness, thinking only of his subject, and 

 its fittest mode of i)resentation, he spoke from the fullne&s of a 

 ripened knowledge, — intent on communicating to others the intel- 

 lectual pleasures of insight he had made his own; and without 

 attempt at oratorical display, his expositions — in simple, direct, and 

 conversational language, were so lucid, satisfying, and convincing, 

 that they enlisted from the beginning and secured to the close, 

 the attentive interest of his auditors. 



His sympathy with the pursuits of the rising generation of phys- 

 icists was ever manifested in a disposition to frequent consulta- 

 tion and interchange of views with them ; as if (aware of the usual 

 tendency to mental ossification with advancing years,) he thus 

 sought by familiar association to drink at the fountain of perennial 

 youth. And surely no one was ever more successful in retaining

 his undinnned faith, hope, and charity, for mankind, than in his 

 intellectual freedom from imdue prejudices, and in his readiness

 of mental attitude, he yet possessed an unusual firmness of resolu- 

 tion. With a manly sturdiness of conviction he presented an 

 unvarying equability of temper and of toleration; and Avith per- 

 fect ctuidor as perfect a courtesy. AVith a (!hara(;teristic dignity of 

 figure of prcsen(!e and of deportment, he preserved an entire free- 

 dom from any shade of arrogance. With a warm and active 

 charity, he still displayed a shrewd perception of character; and 

 while ever responsive to the appeals of real distress, his insight 

 into human nature protected him from being often deceived by the 

 wiles of the designing. Intolerant of charlatanry and imposture, 

 he was capable of exhibiting a wonderful patience with the tedium 

 of honest ignorance. Possessing in earlier life a natural quick- 

 ness of temper, and always a high degree of native sensibility, his
