The consciousness must work with and through its own physical phases of being; they work through adapted nerves and muscles. The sun directly helps vegetable growth; indirectly aids the growth of animal tissues. It helps to wind up the energies in every physical system as literally as it raises the vapor of water into the air to become clouds, to condense and fall again to the earth.

We must, if we would learn to become the true sovereigns of the states of consciousness, as well as of material nature, begin to attach a "rigid mechanical signification" to all the joint activities of the mind-unit and its body. Between the lifting force of the sunbeam working with its many physical allies, and all physical activity, there are definite, necessary, measurable interactions. Heat and light, Nature's great lifting powers, are related to the every-day welfare of human beings in many ways which we have been much too little accustomed to consider.

Every sunbeam is an active lever, and in almost every molecule it can find both its fulcrum and the weight to be lifted. Without its continuous help, directly or indirectly given, to elevate or wind up

the forces with their extensions, in every part of every organic structure, no vegetable growth would be possible, no chick could mature in the egg or begin to run about; no arm could move, and no

brain could promote thought. Mental power is

represented physically by the structure and size of the brain and nervous system, as also by the size and structure of the entire organism, as really as the gravitative force in a cannon ball is represented by its weight and the height to which it has been elevated.

Mind must work through its organism; it must accept and use the conditions imposed upon it by the material side of its nature. Its physical and its psychical activities must work together; for they are but the jointly conditioned phases of one indivisible, individualized existence.

of readers dits

have the bearing of the alleged facts distinctly indicated, while to others this must be quite superfluous. The golden mean is, therefore, but a shifting point, varying as all eye-glasses must vary, to suit the need of different eyes. It seems best to freely repeat such thoughts as are most needed in connection with remaining suggestions, to give, in summing up, a fairly complete outline of the argument, which attempts to show that a conscious immortality for each mind must be an abiding con

stitutional fact. The interests at stake would justify even unneeded iteration.

We claim that each ultimate atom,-whether conditioned by physical properties only; as unquestionably all simply material units may be, so far as anything is now known to the contrary, though we may not have evidence enough to determine this point from sufficient data; or whether conditioned by both physical and psychical properties, as all atoms must be when they possess the capacity to live, to be thrilled by any kind of felt experience, whether of a low or of a high order,-we claim that every atom in the universe, without exception, is, to itself, the axis or centre of the entire universe, in such a sense that it can and does coöperate with all other units in all directions, radiating its influence outward like a true central star; giving and receiving various modes of activity on all sides, and exchanging with its neighbors always on the rigid mathematical basis of equivalent for equivalent of working energy.

In proof of this position, we appeal directly to well known and admitted facts. Whoever is still

doubtful as to the value of the evidence already offered on this point, must take up the subject for himself. He can surely determine in his own mind how any centre of force is able to co-work with other centres of force. With the attention concentrated on any one simple point of departure, if our theory is tenable, all the remaining units of the cosmos will be ranged about it as the sheaves of Joseph's brethren were around about Joseph's sheaf, bowing down before it; they all vibrate in response to its vibrations. But it responds to them all with equal courtesy; for in the great commercial mart of material nature there are no privileged traders enriching themselves at the expense of their fellows.

If we can satisfy ourselves that substances exchange, not innate forces, but modes or ways of working, that they exchange motive tendencies, opposed in direction, in rate or circuit of vibration, or in some occult trait of motion, which can enable them to share equitably in the results, we shall then find no difficulty in comprehending that we ourselves may be each a true material unit; taking unconsciously a full and fair continuous share in the manifold oper
