Therewith Zee began to enter into an explanation of which I understood very little, for there is no word in any language I know which is an exact synonym for vril.  I should call it electricity, except that it comprehends in its manifold branches other forces of nature, to which, in our scientific nomenclature, differing names are assigned, such as magnetism, galvanism, &c.  These people consider that in vril they have arrived at the unity in natural energetic agencies, which has been conjectured by many philosophers above ground, and which Faraday thus intimates under the more cautious term of correlation:—­

“I have long held an opinion,” says that illustrious experimentalist, “almost amounting to a conviction, in common, I believe, with many other lovers of natural knowledge, that the various forms under which the forces of matter are made manifest, have one common origin; or, in other words, are so directly related and mutually dependent that they are convertible, as it were into one another, and possess equivalents of power in their action.  These subterranean philosophers assert that by one operation of vril, which Faraday would perhaps call ’atmospheric magnetism,’ they can influence the variations of temperature—­in plain words, the weather; that by operations, akin to those ascribed to mesmerism, electro-biology, odic force, &c., but applied scientifically, through vril conductors, they can exercise influence over minds, and bodies animal and vegetable, to an extent not surpassed in the romances of our mystics.  To all such agencies they give the common name of vril.”

Zee asked me if, in my world, it was not known that all the faculties of the mind could be quickened to a degree unknown in the waking state, by trance or vision, in which the thoughts of one brain could be transmitted to another, and knowledge be thus rapidly interchanged.  I replied, that there were amongst us stories told of such trance or vision, and that I had heard much and seen something in mesmeric clairvoyance; but that these practices had fallen much into disuse or contempt, partly because of the gross impostures to which they had been made subservient, and partly because, even where the effects upon certain abnormal constitutions were genuinely produced, the effects when fairly examined and analysed, were very unsatisfactory—­not to be relied upon for any systematic truthfulness or any practical purpose, and rendered very mischievous to credulous persons by the superstitions they tended to produce.  Zee received my answers with much benignant attention, and said that similar instances of abuse and credulity had been familiar to their own scientific experience in the infancy of their knowledge, and while the properties of vril were misapprehended, but that she reserved further discussion on this subject till I was more fitted to enter into it.  She contented herself with adding, that it was through the agency of vril, while I had been placed in the
