PREFACE 
Considerable care lias been taken with the illus- 
trations. They are, with a few exceptions, reproduced 
from my own photographs. In the case of fossils, 
reference is made in foot-notes to the original figures. 
Most of them have been re-drawn, but I fear they have 
suffered somewhat from the difficulty of rendering the 
original lithographs into line work. I am indebted to 
Mr. Charles Hedley, of the A ustralian Museum, for some 
of these drawings, and also for valued advice in pre- 
paring the work. To Mr. Catbels is due the credit of 
admirable reproductions of some of my own sketches. 
1 must also express my indebtedness to two of my 
students, Miss Elsie English and Mr. Carl A. 
Sussmilcli; the former read the proof-sheets and 
compiled the index, the latter verified many references 
in the list of fossils, and worked out the section (fig*. 
46) at Bundanoon. 
Finally, I may say that the book, as it leaves my 
hands, falls very far short of my ideal. I can only 
hope that perhaps its very shortcomings will induce 
someone with resources more ample than mine to take 
the matter in hand, and give us a work altogether 
worthy of the subject.
