68 



Perhaps as a period of fifteen years has elapsed since Mr. 

 Tutt summarised the information then obtainable on this 

 subject, and as fresh facts and developments have been 

 rapidly accumulating during this period, the time is now 

 ripe for a reconsideration of the whole question. 



For this reason I have ventured to make these remarks, in 

 the hope that some one more capable than I am may be 

 induced to undertake the task of gathering together all the 

 new facts and of testing the old hypothesis in the light of 

 these new facts. 



I wish now to thank the Officers and Council for their 

 help and co-operation, which has been so freely accorded me, 

 and the members generally for their courtesy and goodwill 

 during the year of my occupation of this chair. 



Finally it only remains for me to give place to my successor, 

 Mr. Robert Adkin, under whose experienced guidance we 

 confidently look forward to a year of increased prosperity.
