[Renewed whispering and laughter among the young people.
Professor (stops and casts a severe look round). Mediumistic energy has been known to mankind for ages: prophecy, presentiments, visions and so on, are nothing but manifestations of mediumistic energy. The manifestations produced by it have, I say, been known to mankind for ages. But the energy itself has not been recognised as such till quite recently—not till that medium, the vibrations of which cause the manifestations of mediumistic energy, was recognised. In the same way that the phenomena of light were inexplicable until the existence of an imponderable substance—an ether—was recognised, so mediumistic phenomena seemed mysterious until the now fully established fact was recognised, that between the particles of ether there exists another still more rarefied imponderable substance not subject to the law of the three dimensions....
[Renewed laughter, whispers, and giggling.
Professor (again looks round severely). And just as mathematical calculations have irrefutably proved the existence of imponderable ether which gives rise to the phenomena of light and electricity, so the successive investigations of the ingenious Hermann, of Schmidt, and of Joseph Schmatzhofen, have confirmed beyond a doubt the existence of a substance which fills the universe and may be called spiritual ether.
Fat Lady. Ah, now I understand. I am so grateful....
Leoníd Fyódoritch. Yes, but Alexéy Vladímiritch, could you not ... condense it a little?
Professor (not heeding the remark). And so, as I have just had the honor of mentioning to you, a succession of strictly scientific experiments have made plain to us the laws of mediumistic phenomena. These experiments have proved that, when certain individuals are plunged into a hypnotic state (a state differing from ordinary sleep only by the fact that man's physiological activity is not lowered by the hypnotic influence but, on the contrary, is always heightened—as we have recently witnessed), when, I say, any individual is plunged into such a state, this always produces certain perturbations in the spiritual ether—perturbations quite similar to those produced by plunging a solid body into liquid matter. These perturbations are what we call mediumistic phenomena....
[Laughter and whispers.
Sahátof. That is quite comprehensible and correct; but if, as you are kind enough to inform us, the plunging of the medium into a trance produces perturbations of the spiritual ether, allow me to ask why (as is usually supposed to be the case in spiritualistic séances) these perturbations result in an activity on the part of the souls of dead people?
Professor. It is because the molecules of this spiritual ether are nothing but the souls of the living, the dead, and the unborn, and any vibration of the spiritual ether must inevitably cause a certain vibration of its atoms. These atoms are nothing but human souls, which enter into communication with one another by means of these movements.
