ABSTRACT OF PROCEEDINGS. IlU. 



that the evidence supported Prof. Taylor's view that the 

 isolation of the continent took place much later than the 

 Cretaceous. 



Mr. Dun dealt with the distribution of the marsupials 

 and their progenitors. The Australian stocks probably 

 came through Eurasia, and the forms found in Patagonia 

 represent relics of a dying fauna. 



Dr. Walkom considered the evidence from the Tertiary 

 fossil plants indecisive. In Cretaceous (probably Upper 

 Cretaceous) times, Australia was divided by a sea from 

 North to South, and it is a matter of doubt whether the 

 land connection with Eurasia was to Western or to Eastern 

 Australia. 



Dr. Danes appealed for more study of the climatic factor 

 in the matter of migrations. 



After remarks by other members the results of the 

 discussion were briefly summed up by the Chairman.
