preface summarising Ettingshausen 's conclusions the Tertiary Flora in general contains 



the element? of all the living floras of the globe. This conclusion he based, first on the occurrence in the 

 European Tertiary Flora of Alnus, &c, and other genera peculiar to the Northern Hemisphere, together 

 with .... Eucalyptus and other genera particular to the Southern Hemisphere." 



At p. 78 E ttingshausen quotes his previous conclusions tha 1 :. "the elements of floras are united, 

 not only in the Tertiary Flora of Europe, the Arctic Regions, North America, and of Australia, but also 

 in the Tertiary Floras of other portions of the globe. The facts just mentioned confirm this eviii more 

 strongly. Besides, I am able to state the same result from facts obtained by examining the Tertiary 

 Flora of New Zealand. . . . There is now scarcely any doubt that the general character of all 

 Tertiary Floras of the globe is one and the same in regard to the mixture [including Eucalyptus in both 

 hemispheres. — J.H.M.] which they exhibit, and carried, until the separation of the element? of florals into 

 th 1 special floras towards the present period." 



See also the general conclusions at p. 81. 



See also some stratigraphical notes, concerning Dalton, near Gunning, New 

 South Wales : — 



The fossil plants of this locality are found in layers of clay, sand, and marl, which are ferruginous. 

 Similar strata occur also in New England. Mr. G. S. Wilkinson regards these strata as at least Lower 

 Miocene. 



The author then enumerates the plants of peculiar interest, and proceeds — 



"Among these, however, there are no forms of specifically Australian character, which would 

 appear to have retreated into the background altogether. A Pittosporum and a Eucalyptus are the only 

 plants of this kind. ... I regard the Fossil Flora of Dalton as Eocene." (p. 9.) 



For further stratigraphical notes of certain localities containing Eucalyptus 

 deposits, see Etheridge in the same work, p. 185, in regard to the Emmaville deposit 

 containing E. Diemenii, E. Houtmanni, E. Hayi, and p. 187 in regard to a second 

 Emmaville locality containing E. Mitchelli. 



"I believe that Ettingshausen's conclusions as to the character of the flora and its resemblance to 

 the flora of other parts of the world, as based on the determinations of the Dalton and Vegetable Creek 

 fossils are utterly wrong." (Deane, Proc. Linn. Hoc. N.S.W., xx, 654, 1896.) 



" Messrs. Hall and Pritchard suggest that the beds at Dalton and Vegetable Creek, which have the 

 same lithological character, and which Ettingshausen considered Eocene, may have to be referred back 

 to the Cretaceous." (Deane, ib., xxi, 857, 1897.) 



At p. 16 Ettingshausen gives E. oceanica linger, of the Tertiary of Europe; 

 E. sibirica Heer, of the Tertiary of the Arctic Zone; E. americana Lesq., of the Tertiary 

 of North America, as the nearest relations to the New South Wales and Victorian fossils 

 E. Delftii Ett., E. obliqua L'Herit,, E. Pluti McCoy.
