The devil knows

Sir: Mr Simon Raven tells us (3 April) that 'we, with benefit of science, know that there is no devil'. Having speculated ruinously on the Grand National, may I, while thanking him for his hot tip, be told which scientific experiment has demonstrated this notable con- clusion, and in which learned journal or monograph I may read the report of that experiment. I can't risk another smash.
