The competition is in no way confined to members of the 
Society, nor to residents in Australia, but is 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
