Whilst the greatest effort has been made to ensure the quality of this text, due to the historical nature of this content, in some rare cases there may be minor issues with legibility. Some were too technical, some too bulky and expensive and some so mixed with other error as to be impossible to recommend. Not a few were written by those who were well informed on the scientific phases of Spiritualism, the findings of the Society of Psychical Research Or the doings of mediums and seances, but whose authors appeared either ignorant of or indifferent to the Bible, which to the Christian, of course, holds the first place and is of final authority.
