§ 1. Visual hallucinations may present various degrees of apparent ex-ternalisation, beginning with what is scarcely more than a picture in the mind's eye, and ending with a percept which seems quite on a par with all surrounding objects. Examples of these varieties in telepathic phantasms . . 390-397

§ 2. Examples of completely externalised phantasms. One case (No. 242) is remarkable in that the actual percipient had no direct connection with the agent, but was in the vicinity of a person intimately connected with him 397-411

§ 3. Cases where the hypothesis of illusion or mistaken identity has to be taken into account. This hypothesis would not exclude a telepathic origin, as telepathic illusions are quite conceivable phenomena. But more probably these cases were hallucinations; and if so, their telepathic origin would hardly be doubtful. One of them (No. 243) exhibits the point of a previous compact between the agent and percipient, that whichever died first should endeavour to make the other sensible of his presence. Such a compact, latent in either mind, may quite conceivably have some conditioning efficacy .... 412-417

§ 4. Cases of a rudimentary type - perhaps of arrested development - not representative of a human form; they might be compared to a motor effect which is limited to a single start or twitch. The class is too small to carry any conviction on its own account, but its type is not so improbable as might at first appear. .......... 417-419

§ 5. Certain cases involving no coincidence with any ostensibly abnormal condition of the agent. (1) Instances where several percipients, at different times, have had hallucinations representing the same person, in whom a specific faculty for producing telepathic impressions may therefore be surmised 419-426

§ 6. And (2) instances where a presumption that a hallucination was not purely subjective is afforded by peculiarities of dress or aspect in the figure presented ........... 426-431

§ 7. And (3) instances where the phantasm appears at a time when the person whom it represents is, unknown to the percipient, actually approaching him, with thoughts more or less consciously turned in his direction 431-432
