The competitions are in no way confined to members of the 

 Society, nor to residents in Australia, but are open to all without 

 any restriction whatever, excepting that a prize will not be awarded 

 to a member of the Council for the time being ; neither will an 

 award be made for a mere compilation, however meritorious in its 

 way. The communication, to be successful, must be either wholly 

 or in part the result of original observation or research on the 

 part of the contributor. The Society is fully sensible that the 

 money value of the prize will not repay an investigator for the 

 expenditure of his time and labour, but it is hoped that the honour 

 will be regarded as a sufficient inducement and reward. The 

 successful papers will be published in the Society's annual volume. 

 Fifty reprint copies will be furnished to the author free of expense. 

 Competitors are requested to write upon foolscap paper — on one 

 side only. A motto must be used instead of the writer's name, 

 and each paper must be accompanied by a sealed envelope bearing 

 the motto outside, and containing the writer's name and address 

 inside. All communications are to be adressed to the Honorary 

 Secretaries.
