"Almost every known body in nature is susceptible of three several states of existence,--the solid, the liquid, the aeriform. These conditions depend on the quantity of heat they contain. The same object at one moment may be liquid; at the next moment solid; at the next aeriform. The water that flows before your gaze may stop consolidated into ice, or ascend into air as a vapour. Thus is man susceptible of three states of existence,--the animal, the mental, the spiritual; and according as he is brought into relation or affinity with that occult agency of the whole natural world, which we familiarly call heat, and which no science has yet explained, which no scale can weigh, and no eye discern, one or the other of these three states of being prevails, or is subjected." I still continued silent, for I was unwilling discourteously to say to a stranger so much older than myself, that he seemed to me to reverse all the maxims of the philosophy to which he made pretence, in founding speculations audacious and abstruse upon unanalogous comparisons that would have been fantastic even in a poet. And Sir Philip, after another pause, resumed with a half smile,-- "After what I have said, it will perhaps not very much surprise you when I add that but for my belief in the powers I ascribe to trance, we should not be known to each other at this moment." "How? Pray explain!" "Certain circumstances, which I trust to relate to you in detail hereafter, have imposed on me the duty to discover, and to bring human laws to bear upon, a creature armed with terrible powers of evil. This monster, for without metaphor, monster it is, not man like ourselves, has, by arts superior to those of ordinary fugitives, however dexterous in concealment, hitherto for years eluded my research. Through the trance of an Arab child, who, in her waking state, never heard of his existence, I have learned that this being is in England, is in L----. I am here to encounter him. I expect to do so this very night, and under this very roof." "Sir Philip!" "And if you wonder, as you well may, why I have been talking to you with this startling unreserve, know that the same Arab child, on whom I thus implicitly rely, informs me that your life is mixed up with that of the being I seek to unmask and disarm,--to be destroyed by his arts or his agents, or to combine in the causes by which the destroyer himself shall be brought to destruction." "My life!--your Arab child named me, Allen Fenwick?"
