The Subscriptions of SI for the year ending 30th June, 1911, are 

 no'w due. 



Members whose subscriptions are still unpaid are requested to be so 

 kind as to remit the amount as soon as possible to the Assistant General 

 Secretary, P.O. Box 1497, Cape Town. Unless such Members pay the amount 

 due at an early date great inconvenience and probably unnecessary expense 

 will be caused, as it is very difficult to determine what number of copies of 

 the Journal will be required, provision having to be made to supply every 

 member whose name appears on the register. The Council therefore appeals 

 to every member for support and co-operation, and asks that outstanding 

 subscriptions be paid without delay. The Journal will be sent only to those 

 whose arrear subscriptions are paid. 



Cheques, etc., should be crossed and made payable to the Association ; 

 6d. should be added to country cheques for exchange.
