PREFACE TO TILE SECOND EDITION. 
This first edition of this book was gold out in a few 
mouths, This may bo taken as a proof that the work, 
which was published with some diffidence, has met 
with the approval of tho public. It was my endeavour 
to introduce the student to a practical method of 
studying ( leology — by handling specimens, and 
examining rocks along the cliff ami on the hillside 
in Natures roofless school.” Without sacrificing 1 
simplicity, I have, when possible, given references 
to reliable sources ol information, thus in a manner 
helping the student to continue his study on a higher 
grade. 
Reference is made ropeatedly in tho text to the late 
I’l-ofessor do Koninck’s Atlas of Now South Wales 
Paleozoic Fossils, published at Brussels in 1873 . 
This work is now available in English, with all the 
original beautiful lithographic plates . 1

photographs to supply fresh illustrations. In studying 
tho country west of Mount Victoria I received con”

over much of tho ground with me. When most of my 
notos wore made I learned that a map had already been 
prepared, cpiite independently, by Mr. C. L. Ball. This 
gentleman, who is intimately acquainted with tho
