1. The Tertiary Flora of Australia ; by Dr. Const antin, 

 Baron von Ettingshausen. English translation, edited by R. 

 Etheridge, Jr. Sidney, 1S88. — The appearance of an English 

 translation of Baron von Ettingshausen's two important memoirs 

 on the later fossil floras of Australia will do much to extend the 

 knowledge of this subject. The memoirs originally appeared in 

 the Denkschriften of the Vienna Academy (vols, xlvii, 1883, and 

 liii, 1886), and were chiefly based on collections made by the 

 Geological Survey of New South Wales, in the Memoirs of which 

 the translation appears. An analysis of the results was prepared 

 some time since, and will be found in the Eighth Annual Report 

 of the IT. S. Geological Survey (pp. 812-814), soon to appear. 

 The useful tables of distribution accompanying the original mem- 

 oirs are introduced, and to that of the second part is appended a 

 similar table of the Tertiary plants of New Zealand, belonging 

 to a paper of later date (Denkscriften Wien. Akad., vol. liii, 

 1887) on the fossil flora of New Zealand, but the descriptions 

 and figures of that memoir are not included in the present work. 

 The first part was translated by Mr. Arvid Neilson, and the 

 second by the author. Some valuable stratigraphical notes by 

 the editor are appended. The illustrations are reproduced from 

 the original litho-plates, of which there are fifteen, but the figures 

 are often too much crowded. These papers have afforded the au- 

 thor a new occasion to express his well-known views as to the 

 homogeneity of all Tertiary floras, and that of Australia, he 

 claims, resembles that of Europe and the Arctic regions more 

 closely than it does the present living flora of Australia.

 of this society contains a paper on the Huronian of Canada by R. 

 Bell ; on Nematophyton by D. P. Penhallow, with an introduc- 

 tory note by Sir Wm. Dawson, which concludes that Prototaxi-

 that it is beyond doubt an Alga ; on remarkable organisms of the
