"I (the conjuror names himself), conjure thee, spirit (giving the name of the particular spirit to be evoked), in the Name of the Great Living God, to appear to me in such a form (indication of form desired); otherwise Saint Michael the invisible, the Archangel, will cast thee into the deepest of all the pits of hell. Come, thou, then (naming spirit), come thou; come, come and do my will."
