this work. The classification I have elaborated for my
purpose is totally different to that employed by Jerdon and familiar
to Indian ornithologists; but a departure from Jerdon's arrangement
was merely a question of time, and no better opportunity than the
present for readjusting the classification of Indian birds appeared
likely to present itself. I have therefore adopted a new system, which
I have fully set forth in my other work.

I take this opportunity to present the readers of Mr. Hume's work with
portraits of Mr. Hume himself, of Mr. Brian Hodgson, the late Dr.
Jerdon, and the late Colonel Tickell.
