"A System Of Logic, Ratiocinative And Inductive (Vol. 1 of 2)"
John Stuart Mill
The existing properties of that woman, which permitted some special spirit to frequently dwell and commune intelligibly with her, and be cognizable by her inner senses as a dweller in her household, as her familiar,-such properties would enable her to perceive the form and hear the voice of another spirit, who might be called to her presence for an urgent purpose, as naturally as the outer eye which sees one external form is competent to see another.
"Witchcraft of New England Explained by Modern Spiritualism"
Allen Putnam
