Waller encloses a proof of his final article on radiation and asks BR if alterations should be made and if he would like to write a message to be included. The Sunday Chronicle will soon cease to exist as a result of a business deal and will be replaced by the Daily Mirror and the Sunday Pictorial. Waller feels it is futile to carry on a dispute with Rotblat concerning the responsibility of a paper that will no longer exist. Waller feels the series was worthwhile and thanks BR for all his help.
