AN

ESSAY

TOWARDS

A THEORY

OF

APPARITIONS.

BY

JOHN FERRIAR, M. D.

A thousand fantasies

Begin to throng into my memory,

Of calling shapes, and beck’ning shadows dire,

And airy tongues, that syllable men’s names

On sands, and shores, and desert wildernesses.

These thoughts may startle well, but not astound.
