A NUMBER of amateurs are making films frequently of unique scientific interest. It may be that by patience an ornithologist has managed to secure some pictures of bird behaviour which may never be duplicated for a generation or more. It may be that a medical man has made a motion-picture record of a rare case-history or a film of a particular method of conducting an operation. It may be that an anthropologist has secured film records of fast disappearing tribal ceremonies or, in the case of our own country, a folk survival. Any worker in any field may indeed make a record which has more than a personal interest.
