 features permits such a farreaching conclusion from observations rather 

 rapid and widely dispersed.

 In the paper of Mr. Andrews (Geographical Unity of 

 Eastern Australia in Late and Post Tertiär y Time, 

 with Applications to Biologie al Problems. By E. C. 

 Andrews, B. A. Department of Mines, Sydney. Read before the Ptoyal 

 Society of. N. S. Wales, November 2. 1910. Journal and Proceedings ofthe 

 Royal Society of N. S. Wales, Vol. XLIV.) the great problém of the tef- 

 tiary and posttertiary history of Eastern Australia and its physio- 

 graphical évolution is dealt with and treated in a most convincing 

 and conclusive inanuer. As Mr. Andrews does not go into détails 

 concerning the features of North Eastern Australia, but contents him- 

 self with stating the facts of rather generál character, which help to 

 confirm his thesis and as I completely agree with the results of his 

 investigations, I consider it as rather superfluous to dwell longer at 

 that excellent study, which will certainly be much more compréhen- 

 sible to the generál scientific world than both the other papers, the 

 methods of which might not be so easily understood by non physio" 

 graphers. fc 



I shall be able to avail myself further on of sonie quotations 

 from Mr. Andrews' paper, which in my conviction show the conver- 

 gence of opinions in the most important points, which I attempt to 

 discuss.

 Mr. Taylor 1 ) expounds most persuasively the shifting of the 

 continental divide from east to the west, he shows how the new ri- 

 vers flow against the generál slope ofthe country, how they are joined 

 in an abnormal way „in boat-hook bends" by their upper tributaries 

 and dwells also on another feature, which seems to be the most 

 convincing. (Page 8 — 9). „A third feature usually connected with new 

 divides ís the presence of shallow lakes on a somewhat undulating 

 region. We notice many such if we trace the Great Divide from 

 north to south. They usually represent upper portions of rivers per- 

 ched on the top of the New Divide, which cannot flow into their old
