I will preface these remarks by saying that I am a fierce believer in the fundamental equality of the sexes—after all, I am told that they are both necessary for the survival of the human race—or at least this seems to be so at the moment, though the way things are going it might at some time cease to be so. A second caveat is that I am not going to pretend to talk about the whole field of attainment, it would be inevitable that one would say too little about too much. However, if any of the audience wish to ask questions about any aspect of the topic in which they are interested I shall attempt to answer.
