Note 508 — Chapter V · THE DEMONOLOGY OF GHOSTS AND SPRITES AND BOGEYS.

Since this section was written Dr G. Weicker’s treatise Der Seelenvogel has appeared. As the substance of his argument as to the soul-origin of the Sirens had been previously published in a dissertation De Sirenibus Quaestiones Selectae (Leipzig, 1895) he had long anticipated my view and I welcome this confirmation of a theory at which I had independently arrived, a theory which indeed must occur to everyone who examines the art-form of the Sirens. I regret that his work was known to me too late for me to utilize the vast stores of evidence he has accumulated.
