This course was taken with John Palmer, and the true secret of his mysterious power of vision detected in an instant.

On applying the ophthalmoscope, the committee ascertained in a moment that the boy's eye was abnormally shaped. A natural, perfect eye is perfectly round. But the eye examined was exceedingly flat, very thin, with large iris, flat lens, immense petira, and wonderfully dilated pupil. The effect of the shape was at once apparent. It was utterly impossible to see any object with distinctness at any distance short of many thousands of miles. Had the eye been elongated inward, or shaped like an egg—to as great an extent, the boy would have been effectually blind, for no combination of lens power could have placed the image of the object beyond the coat of the retina. In other words, there are two common imperfections of the human organ of sight; one called myopia, or "near-sightedness;" the presbyopia, or "far-sightedness."

"The axis being too long," says the report, "in myopic eyes, parallel rays, such as proceed from distant objects, are brought to a focus at a point so far in front of the retina, that only confused images are formed upon it. Such a malformation, constituting an excess of refractive power, can only be neutralized by concave glasses, which give such a direction to rays entering the eye as will allow of their being brought to a focus at a proper point for distant perception."

"Presbyopia is the reverse of all this. The antero-posterior axis of such eyes being too short, owing to the flat plate-like shape of the ball, their refractive power is not sufficient to bring even parallel rays to a focus upon the retina, but is adapted for convergent rays only. Convex glasses, in a great measure, compensate for this quality by rendering parallel rays convergent; and such glasses, in ordinary cases, bring the rays to a focus at a convenient distance from the glass, corresponding to its degree of curvature." But in the case under examination, no glass or combination of glasses could be invented sufficiently concave to remedy the malformation. By a mathematical problem of easy solution, it was computed that the nearest distance from the unaided eye of the patient at which a distinct image could be formed upon the retina, was two hundred and forty thousand miles, a fraction short of the mean distance of the moon from the earth; and hence it became perfectly clear that the boy could see with minute distinctness whatever was transpiring on the surface of the moon.

Such being the undeniable truth as demonstrated by science, the declaration of the lad assumed a far higher value than the mere dicta of spiritualists, or the mad ravings of a monomaniac; and the committee at once set to work to glean all the astronomical knowledge they could by frequent and prolonged night interviews with the boy.

It was on the night of January 9, 1876, that the first satisfactory experiment was tried, testing beyond all cavil or doubt the powers of the subject's eye. It was full moon, and that luminary rose clear and dazzlingly bright. The committee were on hand at an early hour, and the boy was in fine condition and exuberant spirits. The interview was secret, and none but the members of the committee and the parents of the child were present. Of course the first proposition to be settled was that of the inhabitability of that sphere. This the boy had frequently declared was the case, and he had on several previous occasions described minutely the form, size and means of locomotion of the Lunarians. On this occasion he repeated in almost the same language, what he had before related to his parents and friends, but was more minute, owing to the greater transparency of the atmosphere and the experience in expression already acquired.

The Lunarians are not formed at all like ourselves. They are less in height, and altogether of a different appearance. When fully grown, they resemble somewhat a chariot wheel, with four spokes, converging at the center or axle. They have four eyes in the head, which is the axle, so to speak, and all the limbs branch out directly from the center, like some sea-forms known as "Radiates." They move by turning rapidly like a wheel, and travel as fast as a bird through the air. The children are undeveloped in form, and are perfectly round, like a pumpkin or orange. As they grow older, they seem to drop or absorb the rotundity of the whole body, and finally assume the appearance of a chariot wheel.

They are of different colors, or nationalities—bright red, orange and blue being the predominant hues. The reds are in a large majority. They do no work, but sleep every four or five hours. They have no houses, and need none. They have no clothing, and do not require it. There being no night on the side of the moon fronting the sun, and no day on the opposite side, all the inhabitants, apparently at a given signal of some kind, form into vast armies, and flock in myriads to the sleeping grounds on the shadow-side of the planet. They do not appear to go very far over the dark rim, for they reappear in immense platoons in a few hours, and soon spread themselves over the illuminated surface. They sleep and wake about six times in one ordinary day of twenty-four hours. Their occupations cannot be discerned; they must be totally different from anything upon the earth.

The surface of the moon is all hill and hollow. There are but few level spots, nor is there any water visible. The atmosphere is almost as refined and light as hydrogen gas. There is no fire visible, nor are there any volcanoes. Most of the time of the inhabitants seems to be spent in playing games of locomotion, spreading themselves into squares, circles, triangles, and other mathematical figures. They move always in vast crowds. No one or two are ever seen separated from the main bodies. The children also flock in herds, and seem to be all of one family. Individualism is unknown. They seem to spawn like herring or shad, or to be propagated like bees, from the queen, in myriads. Motion is their normal condition. The moment after a mathematical figure is formed, it is dissolved, and fresh combinations take place, like the atoms in a kaleidoscope. No other species of animal, bird, or being exist upon the illuminated face of the moon.

The shrubbery and vegetation of the moon is all metallic. Vegetable life nowhere exists; but the forms of some of the shrubs and trees are exceedingly beautiful. The highest trees do not exceed twenty-five feet, and they appear to have all acquired their full growth. The ground is strewn with flowers, but they are all formed of metals—gold, silver, copper, and tin predominating. But there is a new kind of metal seen everywhere on tree, shrub and flower, nowhere known on the earth. It is of a bright vermilion color, and is semi-transparent. The mountains are all of bare and burnt granite, and appear to have been melted with fire. The committee called the attention of the boy to the bright "sea of glass" lately observed near the northern rim of the moon, and inquired of what it is composed. He examined it carefully, and gave such a minute description of it that it became apparent at once to the committee that it was pure mercury or quicksilver. The reason why it has but very recently shown itself to astronomers is thus accounted for: it appears close up to the line of demarcation separating the light and shadow upon the moon's disk; and on closer inspection a distinct cataract of the fluid—in short, a metallic Niagara, was clearly seen falling from the night side to the day side of the luminary. It has already filled up a vast plain—one of the four that exist on the moon's surface—and appears to be still emptying itself with very great rapidity and volume. It covers an area of five by seven hundred miles in extent, and may possibly deluge one half the entire surface of the moon. It does not seem to occasion much apprehension to the inhabitants, as they were soon skating, so to speak, in platoons and battalions, over and across it. In fact, it presents the appearance of an immense park, to which the Lunarians flock, and disport themselves with great gusto upon its polished face. One of the most beautiful sights yet seen by the lad was the formation of a new figure, which he drew upon the sand with his finger.
