"There is magic of two kinds,--the dark and evil, appertaining to witchcraft or necromancy; the pure and beneficent, which is but philosophy, applied to certain mysteries in Nature remote from the beaten tracks of science, but which deepened the wisdom of ancient sages, and can yet unriddle the myths of departed races." "Sir Philip," I said, with impatient and angry interruption, "if you think that a jargon of this kind be worthy a man of your acquirements and station, it is at least a waste of time to address it to me. I am led to conclude that you desire to make use of me for some purpose which I have a right to suppose honest and blameless, because all you know of me is, that I rendered to your relation services which can not lower my character in your eyes.

"I accept no conditions for my confidence, though I think the better ofyou for attempting to make them. If I live, you will seek me yourself, and implore my aid. Meanwhile, listen to me, and--" "No; I prefer the rain and the thunder to the whispers that steal to my ear in the dark from one of whom I have reason to beware." So saying, I stepped forth, and at that moment the lightning flashed through the arch, and brought into full view the face of the man beside me. Seen by that glare, it was pale as the face of a corpse, but its expression was compassionate and serene. I hesitated, for the expression of that hueless countenance touched me; it was not the face which inspires distrust or fear. "Come," said I, gently; "grant my demand. The casket--"
