 This last line indicates, in particular, that Henry Sidgwick, whose name did not appear among the list of authors of these works, was in substantial agreement with their claims, which certainly appears to be the case. As Broad, a later sympathizer, summarized one of the main conclusions of the most comprehensive of the studies, the Census of Hallucinations: “About one visual hallucination in sixty-three occurs within a period of twenty-four hours round about the death of the person whose apparition has been ‘seen.’ If such deal-coincidences were purely fortuitous concurrences of causally independent events the proportion would be about one in nineteen thousand.” Broad concluded that the Census was “a uniquely and meticulously careful contribution to an important branch of their subject.” (Broad 1938: 144)
