always my hope that his name would be associated with mine in it, but although that cannot be, the fact remains, as will be seen from the list of our joint works, that much of what I have done is equally his.
I wish to acknowledge the great obligations I am under to Professor Baldwin Spencer for much assistance during the preparation of this book, and for photographs which have been reproduced in it. He most kindly read over the drafts of the several chapters, and I have benefited by his kindly criticisms and suggestions in their final settlement. I have also to thank him and Mr. F. J. Gillen for generously permitting me to use some of the photographs taken by them in Central Australia.
My thanks are also due to Miss A. J. King for some interesting photographs of Kurnai men and women.
I have to acknowledge my indebtedness to Dr. J. G. Frazer for much kindness and for most valuable suggestions in connection with this work.
The Government Astronomers of New South Wales, Queensland, and South Australia have most willingly supplied me with information as to rainfall and temperature. And to Mr. P. Baracchi, the Government Astronomer of the State of Victoria, are due my especial thanks for the interest which he has taken in this part of my work, and for the suggestions which he has made.
Mr. J. H. Maiden, the Government Botanist for the State of New South Wales, very kindly examined and named a collection of plants from Lake Eyre, some of which have been drawn for this work by Miss Flockton under his direction.
