The price of this Journal to the General Public is two shillings per copy J 

 Every member of the Association is supplied with one copy free, and may I 

 obtain extra copies at one shilling per copy. Applications for copies should I 

 be addressed to the Assistant General Secretary, P.O. Box 1497, Cape Town. 



The monthly numbers of the Journal are bound in such a manner as trig 

 permit of the whole volume being bound together, at the close of the year, 

 in a style uniform with that of the Annual Reports hitherto issued by the 

 Association. 



CORRESPONDENCE.— All communications other than thosei 

 relating to the Journal should be addressed to the Assistant Secretary, P.O. 

 Box 1497, Cape Town. (Telegraphic address: "Scientific," Cape Town.)

 3497, Cape Town.

 contributed by them at the PORT ELIZABETH MEETINGS are requested

SUBSCRIPTION ".-Subscriptions of £1 for the year ending! 

 30th June, 1913, are now due. Members are requested to be so kind as to 

 remit the amount as soon as possible to the Assistant General Secretary, 

 P.O. Box 1479, 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 Jour- 

 nal will be required. 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 subscrip- 

 tions are paid. 



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

 not to the Secretaries or Treasurer individually. 6d. should be added to 

 country cheques for exchange. 



ELEVENTH ANNUAL SESSION.— The 1913 Annual Session-- 

 of the Association will be held at Lourenco Marques during July. 

 Circulars with full particulars will be issued at a later date. 



Cape Town, 1st January, 19 13.
