"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.
