508 MEMORIAL OF JOSEPH HENRY. 



One day, on opening Henry's copy of Young's "Lectures on 

 Natural Philosophy," a book which he had studied more than any 

 other work of science, I read on the fly-leaf, written by his own 

 hand, these words : 



" In Nature's infinite book of secrecy 

 A little I can read. 



Shakespeare. 11 ' 



And did he not read a little "in Nature's infinite book of secrecy"? 

 and did he not read that little carefully and well? May we all read 

 our little in that book as modestly and as reverently as did JOSEPH 

 HENRY.
