researches by Baron Von Ettingshausen, who has been 

 engaged for lully 30 years in endeavours of systematising on 

 the often enigmatic relics of vegetations of former geological 

 periods. Tasmania is also largely interested in these new 

 enquiries of a palaeontologist, who, in the fields of fossil-plauLs, 

 has gained experience rivalled only by those of Goeppert, 

 Heer, Saporta, and Lesquereux, after the founders of vege- 

 table palaeontology, Sternberg, and Brogniart, and some of 

 its earliest jDromoters, leadingly Unger, have passed away. 

 Baron Von Ettingshausen, on this present occasion, alludes 

 extensively to leaf impressions obtained by Dr. E. McCormick 

 (one of the surgeons of Sir James Eoss' antarctic expeditions 

 during the stay of the Erebus and Terror at Hobart) in the 

 travertin of the country adjacent to the entrance of the Der- 

 went ; and this distinguished palaeontologist had likewise 

 an opportunity, through the authorities of the British Museum, 

 to examine the specimens of fossils collected in the same 

 region by Mr. E. M. Johnston, — the very material, of which 

 the last-mentioned zealous and circumspect observer gave 

 already some general accounts, accompanied by lithographic 

 drawings in the proceedings of the Eoyal Society of Tasmania, 

 1873, lb74, 1879, and 1881, determining at the same time the 

 precise geologic age of these tertiary layers. From these 

 united Tasmanian collections Baron Von Ettingshausen has 

 defined 33 species, which he assorts into 21 genera, pertaining 

 to 16 natural orders. As the " Denkschriften der Wiener 

 Akademie " may not reach many of those who, locally, are 

 interested in these enquiries, it may not be out of the way to 

 give a list of the fossils thus named and diagnosed ; excellent 

 lithograms enrich this treatise, so that no difficulty should 

 arise to trace out the now described species under their present 

 designation at the places of discovery ; this is still farther 

 facilitated by citations of Mr. Johnston's illustrations for 20 

 of the species.
