Mr. C. S. Winxryson said we were indebted to Professor 
Liversidge for the information imparted respecting the geology of 
ew Guinea, ring the Australian Geographical Society’s 
expedition up the Strickland River, the Cretaceous formation was 
found almost along its whole length ; and on ascending one ra 
it seemed as if the country were almost flat and undulating, 
in that direction. Professor Liversidge’s observations now prove 
this to be the case, and form a very important contribution to our 
knowledge of that. part of New Guinea.
