untrue. At the same time these results confirm the already 
published views of myself, Hutton, Ameghino and others 
that during Tertiary times there yet existed a continental 
Antarctic landmass to which the neighboring teritories 
were. joined in changed succession. Phytogeographical 
and palaeontological observations as well as the occu- 
rence of Tertiary conifers on the treeless Kerguelen Island 
of to day, and the fact that the fossil species Arauca- 
rioxylon Schleinitzii Goeppert of this island also occurs 
‘in the Magellan Straight go to prove the same fact.
