THIS is the first of a series of six talks by Professor Munro Fox , who is Professor of Zoology at the University of Birmingham and sometime Fellow of Caius College, Cambridge. He is an authority on all zoological matters, and his books include ' Selene, or Sex and the Moon ' and ' Blue Blood in Animals.' In his first talk he will cover the interesting question of whether animals see colours as we do, and if so, what colours they see.
