The annual numbers of suicide deaths for the past 100 years by different methods in England and Wales are presented. It is shown that the numbers of death by 2 methods, domestic gas poisoning and poisoning by solid or liquid substances, vary independently of all other methods. It is concluded that inferences as to cause drawn from aggregated data should be viewed with great caution.
