The hypothetical ether conceived of by scientists, to account for the transmission of light, is not hypothetical to this discoverer. He knows its nature and its power. By the operation of an instrument of his own invention, he can release it at will from the suspension in which it is always held in our atmosphere. It is so liberated, by an almost instantaneous process of intense vibratory action, and passed through a tube the opening of which is no larger than a pin's head, furnishing sufficient power to run a one hundred horse-power engine. The importance of this discovery cannot be conceived; its limit seems boundless; its value cannot be put in figures. Step by step, with a patient perseverance which one day the world will honour, this man of genius has made his researches, fighting with and overcoming difficulties which seemed insurmountable, during years in which no disinterested hands were extended to aid him, no encouraging words of appreciation bestowed upon him by the scientists whom he vainly tried to interest in his experiments; assailed by calumnies, which, emanating from those who should have been the first to extend aid, have over and over pierced his noble heart like poisoned arrows. History will not forget that, in the nineteenth century, the story of Prometheus found a counterpart, and that the greatest man of the age, seeking to scale the heavens to bring down blessings for mankind, met with Prometheus's reward from the vultures of calumny who, up to the present moment, have not spared their talons upon him. The dangerous conditions attending the introductory features of the development of etheric vapour are not yet entirely overcome; but this throws no shadow of a doubt as to the inventor's eventual success in the minds of those who know the magnitude of the difficulties he has already mastered. O. W. Babcock, in an American journal says of this discovery, "Human comprehension is inadequate to grasp its possibilities or power, for prosperity and for peace. It includes all that relates mechanically to travel, manufacture, mining, engineering and warfare. The discoverer has entered a new world, and although an unexplored wilderness of untold wealth lies beyond, he is treading firmly its border, which daily widens as with ever-increasing interest he pursues his explorations. He has passed the dreary realm where scientists are groping. His researches are made in the open field of elemental force, where gravity, inertia, cohesion, momentum are disturbed in their haunts and diverted to use; where, from the unity of origin, emanates infinite energy in its diversified forms," and to this I would add--where he, the discoverer, is able to look from nature up to nature's God, understanding and explaining, as no mortal ever before understood and explained, how simple is the way in which God "works His wonders to perform."
