Haddock also approvingly quotes the following from Dr. M. P. Hatfield, an authority with whom I, personally, am not familiar: "The arrangement of the nerve-envelopes is so like that of the best constructed electrical cables that we cannot help thinking that both were constructed to conduct something very much alike. I know that there are those who stoutly maintain that nerve-force is not electricity, and it is not, in the sense that an electrical battery is the same things as a live man; but nevertheless nerve-force is closely allied to that wonderful thing that for the want of a better and clearer understanding we agree to call electricity."

Haddock adds: "All states of body and mind involve constant molecular and chemical change. The suggestion arises that the brain, with its millions of cells and its inconceivable changes in substance, may be regarded as a transmitting and receiving battery. The brain being a kind of battery, and the nerves conductors of released stored-energy to different parts of the body, by a kind of action similar to the actions of electricity and magnetism, it is suggested that, either by means of the ether, or of some still finer form of matter, discharges of brain energy may be conducted beyond the limits of the body. If the nerve-track corresponds to wires, this refined medium may correspond to the ether-field supposed to be employed in wireless telegraphy. As electrical movements are conducted without wires, or other visible media, so may brain-discharges be conveyed beyond the mechanism of the battery, without the intervention of nerves - except, as they may constitute a part of the battery. Generally speaking, such discharges would originate in two ways: by direct mental action, or by mental or physical states - perhaps by a combination."

In the above quotations, there will be found constant reference to vibrations in the universal ether. That there is a place, and plenty of room, in the scale of eth-eric vibrations for the vibrations of mental-force, may be seen by a reference to the following quotations from eminent authorities:

Professor Gray has said: "There is much food for speculation in the thought that there exists sound waves that no human ear can hear, and color waves of light that no eye can see. The long, dark, soundless space between 40,000 and 400,000,000,000,000 vibrations per second, and the infinity of range beyond 700,000,000,000,000 vibrations per second, where light ceases, in the universe of motion, makes it possible to indulge in speculation."

Professor Williams has said: "There is no gradation between the most rapid undulations or trembling that produce our sensation of sound, and the slowest of those which give rise to our sensations of gentlest warmth. There is a huge gap between them, wide enough to include another world of motion, all lying between our world of sound and our word of heat and light. And there is no good reason whatever for supposing that matter is incapable of such intermediate activity, or that such activity may not give rise to intermediate sensations, provided there are organs fro taking up and sensifying these movements."

A recent writer in the "London Post" says, "The knowledge we gain by experiment brings home to us what a miserably imperfect piece of mechanism our bodies are. The ear can detect the slow-footed sound vibrations that come to us at the rate of between 40 and 40,000 a second. But the whole of space may be quivering and palpitating with waves at all sorts of varying speeds, and our senses will tell us nothing of them until we get them coming to us at the inconceivable speed of 400,000,000,000,00 a second, when again we respond to them and appreciate them in the form of light."

Another writer, an American psychologist, carries on the tale from this point, as follows: "The first indications of warmth comes when the vibrations reach the rate of 35,000,000,000,000 per second. When the vibrations reach 450,000,000,000,000 the lowest visible light ray manifests. Then comes the orange rays, the golden yellow, the pure yellow, the greenish yellow, the pure green, the greenish blue, the ocean blue, the cyanic blue, the indigo, and finally the violet, the highest degree of light which the human eye can register, and which occurs when the vibrations reach the rate of 750,000,000,00,00 per second. Then come the ultra-violet rays, invisible to human sight, but registered by chemical media. In this ultra-violet region lie the 'X Rays' and the other recently discovered high-degree rays; also the actinic rays which, while invisible to the eye, register on the photographic plate, sunburn one's face, blister one's nose, and even cause violent explosions in chemical substances exposed to them, as well as acting on the green leaves of plants, causing the chemical change of transforming carbonic acid and water into sugar and starches. These forms of'dark light,' that is, light too fine to be perceived by the human eye, are but faint indications of the existence of still higher and finer vibrations - the 'finer forces of nature.'"

Oh, yes! There is plenty of space and room in Nature's scale of forces, for the vibrations of mental energy, nerve-force, and personal magnetism, which combines the two. I trust that the foregoing statements of scientific fact have cleared your mind of any lurking doubts on the subject.
