The fourth lecture in the series, 'Simple Signs and Complicated Communications', is considered lost, as there is no known copy of it. If you do have a copy of the recording, the Royal Institution would love it if you got in touch at xmaslectures@ri.ac.uk to help us make all our CHRISTMAS LECTURES available for future generations.
