The Birds of Norfolk. By Henry Stevensox, F.L.S. ; continued by 

 Thomas Southwell, F.Z.S. 3 vols., 8vo. Norwich and London,

 fore more successfully, cultivated than in Norfolk. The assiduity is 

 a point on which we would especially dwell, since we live in daj-s 

 when what passes for work is knocked off as though speed were its 

 only test and the quality of the " output " a matter beneath the 

 notice of the modern biologist. But it has yet to be proved that 

 what is known in another branch of art as "jerry-building" will 

 pay in the end when applied to authorship ; and from our own point 

 of view, perhaps rather antiquated, we are inclined to say that it will 

 not. We seem to have heard not so very long ago of a heaven-sent 

 genius, who, having applied himself (except when lie was otherwise 

 engaged) for a couple of years to a line of study entirely new to 

 him — it was a portion of the anatomy of a particular class of the 

 animal kingdom — was at the end of that time enabled to set the 

 subject in a wholly different light ! That he did so we can readily 

 believe ; but we might put beside it the fact that other men, who 

 had received no spiritual commission and were perhaps only 

 plodding slaves of the scalpel, had employed themselves on the same 

 inquiries ten or even twenty times as long, and yet had failed to 

 arrive at conclusions they would feel warranted in laying before the
