A SCIENTIFIC FILM GROUP of the Association of Scientific Workers was formed about a year ago to encourage the growth of good instructional and documentary films, dealing both with 'pure science' and, perhaps even more important, with science as a social force. The Group has accordingly given shows of approved scientific films in London, Cambridge, Oxford and elsewhere, which have demonstrated that there is a considerable public for such films. To enable this work to continue on a more ample scale in London, however, while complying with L.C.C. regulations, it has now become necessary to consider forming a Scientific Film Society. Such a Society would be open to all interested persons, whether members of the Association of Scientific Workers or not, and would give at least four film shows a year in a London cinema on Sunday afternoons. It would not be possible to sell tickets for such shows to the general public, but a limited number of guest tickets would be available to members. Any profits arising from the Society's work would be devoted exclusively to non-commercial purposes such as the making and adapting of scientific films. Further particulars about the proposed Society can be obtained from the honorary secretary of the Scientific Films Committee, Association of Scientific Workers, Kelvin House, 28 Hogarth Road, London, S.W.7.
