190 TERTIARY ROCKS OF AUSTRALASIA, 



of fruit, leaf impressions, &c.) are devoted to the eluci- 

 dation of the Tertiary lacustrine deposits and their plant 

 remains. 



Prior to the author's investigations certain of the deposits 

 were briefly described by Dr. Milligan, Count Strzelecki, 

 Professor Morris, the illustrious Darwin, and Morton 

 Allport ; and two or three of the plant remains were 

 figured by Strzelecki in his work on " The Physical 

 Description of New South Wales and Van Diemen's 

 Land." It is from such sources, and from various col- 

 lections examined, that the eminent phytologists, Baron 

 von Mueller (Sir Ferd.), of Victoria, and Baron von 

 Ettingshausen, of Vienna, have been enabled recently to 

 make a more systematic investigation of the Tertiary Flora 

 of Tasmania. Tiie investigations of Baron von Ettins-s- 

 hausen are summarised in an abstract recently communi- 

 cated to the Geological Magazine, in which the labours 

 of the author are kindly acknowledged. As the views of 

 Baron von Ettingshausen are of the greatest value in 

 matters pertaining to palseo-botany, the portion dealing 

 more particularly with the Tasmanian Flora is here repro- 

 duced. 



In relation to the Travertin at Geilston, near, Hobart, 

 Baron von Ettingshausen v/rites : — " This Travertin has 

 been ably investigated and written on by Mr. R. M. 

 Johnston. I have examined in the British Museum a
