In the following pages I have endeavoured to indicate the nature of the faculty of Second Sight or Clairvoyance, the means of its development, the use of suitable media or agents for this purpose, and the kind of results that may be expected to follow a regulated effort in this direction. I have also sought to show that the development of the psychic faculties may form an orderly step in the process of human unfoldment and perfectibility.
As far as the nature and scope of this little work will allow, I have sought to treat the subject on a broad and general basis rather than pursue more particular and possibly more attractive scientific lines. What I have here said is the result of a personal experience of some years in this and other forms of psychic development and experimentation.
