edition of his popular work has been brought about. I have merely to
add that, as I was engaged on a work on the Birds of India, I thought
it would be easier for me than for anyone else to assist Mr. Hume.
I was also in England, and knew that my labour would be very much
lightened by passing the work through the press in this country.
Another reason, perhaps the most important, was the fear that, as Mr.
Hume had given up entirely and absolutely the study of birds, the
valuable material he had taken such pains to accumulate for this
edition might be irretrievably lost or further injured by lapse of
time unless early steps were taken to utilize it.

A few words of explanation appear necessary on the subject of the
arrangement of this edition. Mr. Hume is in no way responsible for
this arrangement nor for the nomenclature employed. He may possibly
disapprove of both. He, however, gave me his manuscript unreservedly,
and left me free to deal with it as I thought best, and I have to
thank him for reposing this confidence in me. Left thus to my own
devices, I have considered it expedient to conform in all respects to
the arrangement of my work on the Birds, which I am writing, side by
side, with 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.
