observe that, though the operations of nature seem, at first thought, to be wonderfully complex and mysterious, yet if the views here presented be correct, the marvel is changed; and we are brought to a profound admiration of the _simplicity_ of the means by which the Almighty conducts His material operations. A _single_ agent made to perform processes so infinitely numerous, diversified and apparently complex! How amazing! Simplicity in complexity!--majestic, like the mind of God. THEORY OF MAN. Let the question now be raised--_What is man?_ The answer will have much to do with the remedial system which I aim to teach. For this reason it is thus early introduced. My answer to the above question is as follows: _Man is a threefold being, composed of a body material, a body electrical, and a spirit rational and indestructible._ Let the elements of this definition be a little amplified: 1. _The material body._ This is composed of various metals, earths, carbon, phosphorus, and gases. I need not go into a representation of their multiplied and curious combinations to form the many parts of the body complete. But these are the ultimate elements; and a most superb and wonderful structure they here compose. Yet, notwithstanding all the manifest skillfulness of its contrivance, and the power of its accomplishment, and the niceness and beauty of its execution, it were a useless display if unaccompanied with the invisible agents which compose the two other grand constituents of man, to wit: the body electrical and the spirit, or mind. Without these, it would quickly fall into decay, as we see it when deprived of them, and would be resolved into its original elements again. But to our gross material bodies the Creator has added,
