Human Electro-magnetism


Professor Bain, another eminent authority, tells us: "The structure of

the nervous substances, and the experiments made upon the nerves and

nerve-centres, establish beyond a doubt certain peculiarities as

belonging to the force that is exercised by the brain. This force is of

a current nature; that is to say, a power generated at one part of the

structure is conveyed along an intervening substance and discharged at

som
other part. The different forms of electricity and magnetism have

made us familiar with this kind of action."



Professor Draper, another eminent authority, says: "I find that the

cerebrum is absolutely analogous to in construction to any other nervous

arc. It is composed of centripetal and centrifugal fibres, having also

registering ganglia. If in other nervous arcs the structure is merely

automatic, and can display no phenomena of itself, but requires the

influence of an external agent--the optical apparatus inert save under

the influence of light, the auditory save under the impression of

sound--the cerebrum, being precisely analogous in its elementary

structure, presupposes the existence of some agent to act through it."



Prof. M. P. Hatfield has said: "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 senses that an electrical

battery is not the same thing as a live man; but, nevertheless,

nerve-force is closely allied to that wonderful thing that for want of a

better and clearer understanding we agree to call 'electricity.'"
