The Royal Society of Western Australia was founded in 1914. The Society promotes exchange among scientists from all fields in

visiting scientists, and occasional symposia or excursions on topics of current importance. Members and guests are encouraged 
to attend meetings on the third Monday of every month (March - November) at 8 pm, Kings Park Board offices, Kings Park, 
West Perth, WA 6005. 
Individual membership subscriptions for the 2003/2004 financial year are $50 for ordinary Members and S25 for Student and

The Journal of the Royal Society of Western Australia was first published in 1915. Its circulation exceeds 600 copies. Nearly 100 
of these are distributed to institutions or societies elsewhere in Australia. A further 200 copies circulate to more than 40 
countries. The Society also has over 350 personal members, most of whom are scientists working in Western Australia (see 
website http://www.ecu.edu.au/pa/rswa). The Journal is indexed and abstracted internationally. 
Cover design : The four subjects symbolize the diversity of sciences embraced by the Royal Society of Western Australia. Mangles' 
kangaroo paw ( Anigozanthos manglesii) and the numbat (Myrtnecobius fasciatus) are the floral and faunal emblems of Western 
Australia, and stromatolites are of particular significance in Western Australian geology (artwork: Dr Jan Taylor). The Gogo Fish 
(Mcnamaraspis kaprios) is the fossil emblem of Western Australia (artwork: Danielle West after an original by John Long).
