Summary:

From the Introduction: 'In offering this scientific proof, I have purposely omitted (except in a few instances) all mention of occult or psychic phenomena occurring in India, and have confined myself to instances occurring in Western lands to Western persons. Moreover, I have avoided quoting and citing Hindu authorities, and have, instead, quoted and cited from authorities well known and respected in Western lands, such as the Society for Psychical Research, and the prominent scientists interested in the work of the said society.'
