Sin, 
I have the honour to submit the accompanying Memoir, No. 3 of 
the Pcilceontological Series of the Geological Survey of New South Wales, 
on The Falccozoic and Mesozoic Flora of Australia and Tasmania, by Dr. 
Ottokar Eeistmantel, Professor in the Bohemian Polytechnic University, 
Prague. It has been edited by Mr. Robert Etheridge, junr., Palaeontologist. 
This valuable work comprises chiefly a description of a collection of 
fossil plants forwarded to Professor Eeistmantel, then Palaeontologist to the 
Geological Survey of India, by the late Rev. W. B. Clarke and myself. It 
was originally issued in German in the Falaeontographica, Suppl. Bd. Ill, 
1878-79 (Cassel, 4to). 
When I proposed the publication of an English translation of the 
work, the Professor not only very kindly undertook to furnish the translation, 
but to revise it and supply additional illustrative plates, so as to include later 
information received by him to date, 1887. 
Since then, however, fresh discoveries have enabled us to determine 
more definitely the stratigraphical position of certain formations, the correla- 
tion of which, as suggested by the Professor from the limited data then before 
him, has now to he modified ; and many doubtful points yet await settlement 
which can only he accomplished by further geological survey of particular 
localities. Consequently it has been deemed unnecessary to republish in full 
the quotations from the published works of some authors and the remarks 
thereon which Professor Eeistmantel has given in this Memoir, for they have 
now only an historic interest; but his descriptive references to these works 
are here inserted as they form a valuable record of the literature of the 
subject. 
The palaeontological observations regarding the comparison of the 
Coal-hearing Series of Australia with those of Tasmania, New Zealand, India, 
Africa, &c., are of sjiecial interest; and a lengthy discussion is given as to 
lla 104—89 b
