FBEFACE. 
of my friend Mr. A. W. Clarke, P.Gr.S., of Charters Towers, formerly Government 
Mineralogical Lecturer, to furnish an extensive series of Petrographical Notes on 
Queensland Eocks, the result of at least two years’ assiduous labour. 
It was originally my intention to include in the present volume all that I could 
say regarding the Mines of the Colony, but I had not made great progress when I 
became convinced that this would not only lengthen the work . beyond all reasonable 
limits, but would also be a source of further delay. Notes will be found in the 
following pages on most of the Mining Districts, and I have drawn freely for statistics, 
&c., on “The Mineral Wealth of Queensland,’’* taking care, liow'cver, to bring the 
information up to date where it was possible ; but the Economic Geology of Queensland 
must form the subject of another volume. I am informed that The Honourable 
AV. 0. Ilodgkinson, Minister for Mines and Education, has a Work on this subject in 
preparation.!

PALEONTOLOGY. 
The investigation of the material for the Palaeontology of Queensland and New 
Guinea was commenced in 1881, and has progressed at intervals since that date as 
opportunity would permit during the leisure time of the Writer. 
The Paleontology of Queensland has hitherto been treated only in a disjointed 
and desultory manner, whilst that of New Guinea, to all intents and purposes, is 
untouched and hardly known. The present attempt is the first on which a collective 
account of the Fossil Organic Remains of these countries has appeared. J 
Up to 1872 Sir Richard Owen’s masterly descriptions of the large extinct Mar- 
supialia, a notice by Prof, (now Sir) F. McCoy on some Reptilian Remains, and a few 
Mollusca, and the more extended essay of the late Mr. Charles Moore on the Mesozoic 
Fossils of AYollumbilla, were the only Memoirs of any importance extant. In that year 
there appeared an account of the gatherings of the late Richard Daintroe, C.M.G., by 
Messrs. Etheridge and Carruthers. Since then large collections have been made, chiefly 
through the labours of my Colleague, Mr. R. L. Jack, his Assistants, Mr. W. H. Rands 
and Mr. A. Gibb Maitland, and by the late Mr. James Smith, of Rockhampton, first as 
a private individual and afterwards as Collector for the Geological Survey. In addition 
many separate Papers have appeared, notably “ Carboniferous Marine Fossils,’’ 
“ Mesozoic Fossils from the Palmer River,” and “ Fossil Flora of the Coal Deposits of 
* See No. 48 in the preceding list of Publications. 
t Throughout the Work the paragr.ai)hs written by my Colleague and myself are distinguished by an 
initial (E. or J.) at the end.
