Among the various sciences which curiosity had induced him to explore, He neglected not that which by most is esteemed impious, and by many chimerical.

I speak of those arts which relate to the world of Spirits.

His deep researches into causes and effects, his unwearied application to the study of natural philosophy, his profound and unlimited knowledge of the properties and virtues of every gem which enriches the deep, of every herb which the earth produces, at length procured him the distinction which He had sought so long, so earnestly.

His curiosity was fully slaked, his ambition amply gratified.

He gave laws to the elements; He could reverse the order of nature; His eye read the mandates of futurity, and the infernal Spirits were submissive to his commands.
