We might multiply these _authentic_ accounts indefinitely. Facts analogous to those already mentioned of communications from a distance, whether at the moment of death or in the normal condition of life, are not so rare--without, however, being very frequent--but that every one of our readers may have heard such cited, or perhaps have observed them himself in more than one instance. Besides, experiments made in the realms of magnetism show also that under certain ascertained psychological conditions an experimenter can act upon his subject not only at the distance of a few metres, but of several kilometres, and even of more than a hundred kilometres, according to the sensitiveness of the subject, as well as to the intensity of the magnetizer's will. Moreover, space is not what we suppose. The distance from Paris to London is great for a walker, and was even insurmountable before the invention of boats; it is nothing for electricity. The distance from the Earth to the Moon is great for our present modes of locomotion; it is nothing for attraction. In fact, from an absolute point of view, the space which separates us from Sirius is not a greater part of infinity than the distance from Paris to Versailles, or from your left eye to your right. There is more yet; the separation which seems to us to exist between the Earth and the Moon, or between the Earth and Mars, or even between the Earth and Sirius, is only an illusion due to the insufficiency of our perceptions. The Moon acts constantly upon the Earth, and moves it perpetually. The attraction of Mars for our planet is equally acute, and we in our turn disturb Mars in its course in submitting to the influence of the Moon. We act upon the Sun itself, and make it move as if we touched it. By virtue of attraction, the Moon causes the Earth to turn every month around their common centre of gravity,--a point which travels one thousand seven hundred kilometres below the surface of the globe. The Earth causes the Sun to turn annually around their common centre of gravity, situated four hundred and fifty-six kilometres from the solar centre; all the worlds act upon each other perpetually, so that there is no isolation, no real separation, between them. Instead of being a void separating the worlds from one another, space is rather a connecting link. Now, if attraction thus establishes a real, perpetual, active, and indisputable communication between the Earth and its sisters in immensity, as proved by the precision of astronomical observations, we do not see by what right pretended positivists can declare that no communication can be possible between two beings, more or less distant from each other, either on the Earth or in two different worlds.
