raiocene". Now it is evident from the foregoing that in that case 

 either the volcano-massifs cannot be old-miocene, or the crater-rims 

 do not exist. This statement is of some moment also for regions in 

 other islands. Verbeek ') has asserted in his study of the antiquity 

 of the eruptive rocks in Amboina that they cannot be tertiary, since 

 they are entirely without volcanic shape — in contradistinction to 

 old-miocene and perhaps even older volcanic massifs in Java. From 

 what has been said in this paper it is evident that this argument 

 for the antiquity of the Amboinites carries no weight.
