Furfur

The Thirty-fourth Spirit is Furfur. He is a Great and Mighty Earl, appearing in the Form of an Hart with a Fiery Tail. He never speaketh truth unless he be compelled, or brought up within a triangle, △. Being therein, he will take upon himself the Form of an Angel. Being bidden, he speaketh with a hoarse voice. Also he will wittingly urge Love between Man and Woman. He can raise Lightnings and Thunders, Blasts, and Great Tempestuous Storms. And he giveth True Answers both of Things Secret and Divine, if commanded. He ruleth over 26 Legions of Spirits. And his Seal is this, etc.
