vile PRETEA GLEE 
Struggle for Existence, as illustrated by Birds, were tempting 
themes for treatment, while Nomenclature, which owing to its 
contentious nature I have studied to avoid, and Protection, 
about which so much deplorable and mischievous misunder- 
standing exists, might well be said to demand consideration. 
It will be obvious to nearly every one that the number of 
names of Birds included in a work of this kind might be 
increased almost indefinitely. | Whether it will ever be pos- 
sible for me to supply these additions, and others, must depend 
on many things, and not least on the reception accorded by 
the public to the present volume.
