The Society exists for “the encouragement of studies and investigations in Science Art Literature and Philosophy”: publishing results of scientific investigations in its Journal and Proceedings; conducting monthly meetings; awarding prizes and medals; and by liaising with other learned societies within Australia and internationally. Membership is open to any person whose application is acceptable to the Society. Subscriptions for the Journal are also accepted. The Society welcomes, from members and non-members, manuscripts of research and review articles in all branches of science, art, literature and philosophy for publication in the Journal and Proceedings. 2 Journal & Proceedings of the Royal Society of New South Wales, vol. 150, part 2, 2017, pp. 139–142.
