Der sichtbare und der unsichtbare Mensch. Darstellung verschiedener Menschentypen, wie der geschulte Hellseher sie wahrnimmt

Author's Remark.

The author wishes to express his heartiest thanks to the two theosophical collaborators who prepared the illustrations for this book: Count Maurice Prozor, who drew and painted them for him from life, and Miss Gertrude Spink, who spent several days carefully copying them with the airbrush, so that they could be reproduced more effectively through photography.
