From The Athenaeum. Jan. 12, 1861. 



" The records of the success of George Wilson, with all its outbreaks of sym- 

 pathy into other worlds than those of any lecturer the strong, if silent, power 

 with which he drew to him other men . . . the noble courage with which he 

 fought against a capricious and deluding malady, are all set forth in this book so 

 as to make every one who reads it recollect a true, or entertain a new regard for 

 its object. His memory will nerve the energies of many a student to fight on to 

 the end without any arrogance."
