P V EFACE, 
In the years 1878 and 1879 I published, in German, a work* on the Palaeozoic 
and Mesozoic Elora of Eastern Australia, which appeared in the JPalaeonto- 
graphicci, Suppl. Bd. Ill, illustrated by thirty plates of fossil plants. I was 
at that time on the Geological Survey of India, f Calcutta, working out the 
Eossil Elora of the Indian Gondwana- System, which has certain analogies 
with the coal-bearing beds of Eastern Australia. Erom this point of vieAV I 
was also desirous of obtaining a thorough knowledge of the fossil plants of 
Australia as well as of the geological relations in connection with the same. 
The late llev. W. B. Clarke, of Sydney, forwarded to me for this 
purpose in 1S7G a collection of Australian fossil plants, which in 1878 Avas 
supplemented by another smaller, but nevertheless very interesting, series of 
specimens, with such information as appeared useful and necessary for the 
understanding of the relative position of the various fossils. 
Subsequently I also receded several specimens, Avitli further useful 
information, from Mr. C. S. Wilkinson, Government Geologist of Ncav South 
Upon these collections my above-mentioned work on the Australian 
Eossil Elora was based.

work in English. 
This Avas of course a very honourable and Avelcome offer to me, and I 
did my best to ascertain from the original publishers under AA'hat conditions 
the thirty plates could be republished. The AATiting of the manuscript and 
bringing it up to date I Avas willing to undertake myself.
