Charles Maurice Davies 
Mystic London: or, Phases of occult life in the metropolis 

It is perhaps scarcely necessary to say that I use the term Mystic, as applied to the larger portion of this volume, in its technical sense to signify my own initiation into some of the more occult phases of metropolitan existence. It is only to the Spiritualistic, or concluding portion of my work, that the word applies in its ordinary signification.
