think, as lias been suggested in former Prefaces, that 

 rather too much attention is devoted to one special 

 branch of our subject. Lists of birds from new 

 localities and field-notes are of undoubted value 

 and interest, but there are many other ornithological 

 matters of equal importance, which demand deeper 

 study and on which further information is much to 

 be desired.
