THIS book has been out of print for several years 

 and has been somewhat altered for this new edition. 

 The order in which the chapters originally appeared 

 is changed. One chapter dealing mainly with bird 

 life in the Metropolis, a subject treated fully in 

 another work, has been omitted ; two new chapters 

 are added, and some fresh matter introduced 

 throughout the work.
