From the sense of fatigue, from the continual menace of illness by organic derangement, the dwellers in the ether are free. Rest is not for them, as for us, a necessity ensuing on exercise. The body of the superhuman being, inaccessible to fatigue, does not need repose. Unembarrassed by the mechanism of a complicated machine, it subsists and sustains itself by the unaided force of the life which animates it. Its sole physiological function, probably, is the inhalation of ether, a function which, it is easy to conceive, may be exercised without the aid of numerous organs, if we see a whole class of animals--the Batrachian--for whose respiration the bare and simple skin suffices.
If we admit, that the only function which the superhuman being has to exercise is that of respiration, the extreme simplicity of his body will be easily understood. The numerous and complicated organs and apparatus which exist in the bodies of men and animals, have for their object the exercise of the functions of nutrition and reproduction. These functions being suppressed in the creature whom we are considering, his body must be proportionably lightened. Everything is reduced to respiration, and the preservation and maintenance of the faculties of the soul; all is in harmony with those ends. We admire, with good reason, the wise mechanism of the bodies of men and animals; but, if human anatomy reveals prodigies in our structure, marvellous provision in securing the preservation of the individual and his reproduction, what infinitely greater marvels would, if we were but permitted to study it, be revealed by the organization of the body of the superhuman being, in which everything is calculated to secure the maintenance and the perfection of the soul. With what astonishment should we learn the use and the purpose of the different parts of that glorious body, discover the relations of resemblance or of origin between the living economy of the human, and the living economy of the superhuman being, and divine the relations which might exist between the organs of the superhuman being and those which he should assume in another life, still superior, in which he should be the same being, again resuscitated in new glory and fuller perfection!
