This song is fitted to the medium's revelations as given above, and the next point of interest is whether the medium is informed of her success. This we are not told, but we find on page 95 that when another medium had hit the mark, with a sentence now interpreted as a warning of the death of Raymond before it took place, Sir Oliver wrote to the daughter of the medium: 'The reference to the Poet and Faunus in your mother's last script is quite intelligible, and a good classical allusion; you might tell the communicator sometime if there is opportunity.' Plainly he is desirous of letting his mediums know when they succeed and it is fair to suggest that the Hullulu medium found she had hit the mark, the interpretation of the gibberish being 'Honolulu', though Hottentot failed to score. A medium will always follow up a lucky shot and it needs not even an appeal to chance to explain the repetition of the word at the next sitting, after the verification, which was on May 26th (the date of the simultaneous test), the following being the words used:-- (The medium says): 'You could play.' (N. M. L. asks): 'Play what?' (The medium): 'Not a game, a music.' (N. M. L.): 'I'm afraid I can't, Raymond.' (Feda (_sotto voce_): 'She can't do that'): 'He wanted to know whether you could play Hulu-Honolulu.' One of the strongest 'evidential' stories in the book being thus explicable without calling upon the supernatural, any others lose their value even if no explanation can be based on the available facts; but apart from this explanation the choice of the test word throws a light upon the little group tilting the table at Birmingham. With the whole dictionary and all geography from which to choose, they selected a sound which had occurred in a former revelation and therefore had a chance of repetition. If in his laboratory days Sir Oliver examined a substance for the presence of arsenic, he would first test his reagents for the presence of that metal lest they might contain a trace of it and vitiate the experiment. In this test the experimenters did what was equivalent to selecting an arsenic-contaminated test-tube to use in an analysis for that substance. How did the word come to be selected? If the family of this distinguished man had used ordinary caution in formulating the test, they would certainly have chosen a word that had not occurred before, and I think that point must be clear to the reader. But, though they are probably sensible people in ordinary life, when they turn to the spirit world they fall a prey to their dissociated streams, in which was the knowledge that the word or something like it had been used before and was likely to be used again, especially if, as I suggest, the medium knew it had scored. Hence these believers were, as far as concerned their dissociated streams, deliberately introducing a source of error or, in laboratory language, cooking the experiment.
