BIOGRAPHICAL INTRODUCTION. 



(BV THE editor:) 



MR. ALFRED RUSSEL WALLACE, the co-discoverei 

 with Mr. Darwin of the principle of natural selec-

 residing at Leicester in 1844-5 (^s an English master in the 

 Collegiate School), he made the acquaintance of Mr. H. W. 

 Bates, an ardent entomologist, and when, some years later, 

 the desire to visit tropical countries became too strong to be
