§ 1. The case for spontaneous telepathy, being essentially a cumulative one, hardly admits of being recapitulated in a brief and attractive form. Nothing but a detailed study of the evidence - dull as that study is - can justify definite conclusions concerning it. After all, the dulness is perhaps not greater than attaches to the mastery of details in other departments of knowledge; and it cannot be too clearly realised that what the research requires is not sensational incidents, but verified dates ........ 518-519

§ 2. The present instalment of evidence, with all its defects, may yet, by making the idea of telepathy better understood, facilitate collection in the future; and already various difficulties and prejudices show signs of giving way ............ 519-520

§ 3. But though a fair field is sure, in time, to be allowed to the work, its advance must depend on very wide co-operation; and the more so as the several items of proof tend to lose their effect as they recede into the past. The experimental investigations must be greatly extended, the spontaneous phenomena must be far more intelligently watched for and recorded, before the place of telepathy in scientific psychology can be absolutely assured . . . 520
