immortality. Can another body, then, avail to stay the hand of death, and shall man by a second nervous system escape scot free from the ruin of the first? We think not. The laws connecting consciousness with changes in the brain are very definite and precise, and their necessary consequences are not to be evaded by any such means. Consciousness is a complex thing made up of elements, a stream of feelings. The action of the brain is also a complex thing made up of elements, a stream of nerve-messages. For every feeling in consciousness there is at the same time a nerve-message in the brain. This correspondence of feeling to nerve-message does not depend on the feeling being part of a consciousness, and the nerve-message part of the action of a brain. How do we know this? Because the nervous system of animals grows more and more simple as we go down the scale, and yet there is no break that we can point to and say, 'above this there is consciousness or something like it; below there is nothing like it'. Even to those nerve-messages which do not form part of the continuous action of our brains, there must be simultaneous feelings which do not form part of our consciousness. Here, then, is a law which is true throughout the animal kingdom; nerve-message exists at the same time with feeling. Consciousness is not a simple thing, but a complex; it is the combination of feelings into a stream. It exists at the same time with the combination of nerve-messages into a stream. If individual feeling always goes with stream of nerve-messages, does it not follow that when the stream of nerve-messages is broken up, the stream of feelings will be broken up also, will no longer form a consciousness? does it not follow that when the messages themselves are broken up, the individual feelings will be resolved into still simpler elements? The force of this evidence is not to be weakened by any number of spiritual bodies. Inexorable facts connect our consciousness with this body that we know; and that not merely as a whole, but the parts of it are connected severally with parts of our brain-action. If there is any similar connexion with a spiritual body, it only follows that the spiritual body must die at the same time with the natural one. Consider a mountain rill. It runs down in the sunshine, and its water evaporates; yet it is fed by thousands of tiny tributaries, and the stream flows on. The water may
