I. Introductory. 

 You called me to the high office I am about to vacate, 

 partly to do me honour, for which I am very grateful, and 

 partly to relieve me of work during a period of impaired 

 health. For that I am grateful also, but while you have 

 made presiding at your meetings such an entire pleasure, 

 and while I have during the session vicariously eaten more 

 than one good dinner as your representative, I have, on 

 the other hand, for some time past been haunted by the 

 spectre of the Presidential Address, which seemed indeed 

 so very far away when the Council sent a kindly message 

 to me fourteen months ago. And now the time has come 

 for this duty, I cannot refrain from being retrospective to 

 to some extent, as I look back on the address I had the 

 honour of delivering before you just fifteen years ago. 



The objects of an address of a President may be of 

 several kinds. For example, it may include statistical and 

 official records of the progress of the Society, year-book 

 notes of the progress of science in Australasia, the Pacific 

 Islands and Antarctica, and notes on local topics, or sug- 

 gestions for the advancement of science, particularly as 

 concerns our own State.
