Another interesting fact, related to me by the same physician, serves to throw a light upon the connection of vital and physical energies. The doctor in question was treating a patient, who was apparently "obsessed," by means of electricity. The galvanometer needle showed what slight variations in the current there were during the course of the treatment. In the middle of the process, while the patient was conversing with the doctor, she was suddenly "obsessed." _Coincidental_ with this obsession, the galvanometer showed a tremendous and permanent fluctuation, indicating that the resistance of the body to the current had suddenly and greatly changed! Whatever view we may take of the facts, here is, at least, a striking incident, which the current theories of the varying causes of bodily resistance (in these psycho-galvanic reflexes) hardly serve to explain. Can it be that the subject's "etheric body" was in some way disturbed by an invading intelligence, and that this disturbance was manifested in the fluctuations recorded? Is there a nervous fluid, after all, as the magnetizers and mesmerists contend so strongly, but which has been relegated to oblivion since the advent of suggestion and hypnotism? Personally, I believe that there _is_, and I shall indicate very briefly some of my reasons for thinking so. In the _first_ place, the modern hypnotist can very rarely succeed in cultivating clairvoyance in his subject, whereas the records of mesmerism teem with cases which were developed under the old _regime_. Surely the dissimilarity in the effect points to a dissimilarity of cause. It has always appeared to me highly probable that mesmerism and hypnotism are dependent upon entirely different causes, and were not at all the same in the last analysis. In the _second_ place, the exhaustion which "healers" sometimes experience when treating patients of a certain temperament can hardly be due altogether to suggestion. I have been informed by "magnetic" and "spiritual" healers that this feeling of exhaustion is very great when a self-centred, selfish person is being treated, and correspondingly less whenever a generous, large-souled individual is receiving the treatment. "Osteopaths" have told me the same thing. Those possessing an active mind and brain, and who are analytical and unsympathetic by nature, are far harder to treat, and leave a far greater exhaustion, than those who are not so. This bears a very striking resemblance to the "good" and "bad" sitters in the Piper case, and also the Palladino case; in fact, it is true of everyday life, to a certain extent. The more active the mind, the greater the _grasp_ over life and self which we possess, the less susceptible are we to external or internal influences. Let us call to mind in this connection the remark of Dr. Snow in his treatise on _Anaesthetics_, that "the more intelligent the patient, the more anaesthetic is required to put him under."
