Acknowledgments
The first drafts of these essays appeared in the Australasian Medical Journal, The Sydney Bulletin, the Australian Home, Art in Australia, and the Australian Forum. They have nearly all been considerably modified with the growth of knowledge and frequent rewriting. I have to thank Miss Kibble, of the New South Wales Public Library, for assisting me immensely in hunting up many authorities from whom I quote. Without her help this book could never have been written.
