Regarding the illustrations which, according to the implications of the text, accompanied the supplement, the writer was specific. Most of them, he stated, were copies of “drawings taken in the observatory by Herbert Home, Esq., who accompanied the last powerful series of reflectors from London to the Cape. The engraving of the belts of Jupiter is a reduced copy of an imperial folio drawing by Dr. Herschel himself. The segment of the inner ring of Saturn is from a large drawing by Dr. Grant.” A history of Sir William Herschel’s work and a description of his telescopes took up a column of the _Sun_, and on top of this came the details--as the _Journal_ printed them--of Sir John’s plans to outdo his father by revolutionary methods and a greater telescope. Sir John, it appeared, was in conference with Sir David Brewster: After a few minutes’ silent thought, Sir John diffidently inquired whether it would not be possible to effect a _transfusion of artificial light through the focal object of vision!_ Sir David, somewhat startled at the originality of the idea, paused a while, and then hesitatingly referred to the refrangibility of rays and the angle of incidence. Sir John, grown more confident, adduced the example of the Newtonian reflector, in which the refrangibility was corrected by the second speculum and the angle of incidence restored by the third. “And,” continued he, “why cannot the illuminated microscope, say the hydro-oxygen, be applied to render distinct and, if necessary, even to magnify, the focal object?” Sir David sprang from his chair in an ecstasy of conviction, and, leaping half-way to the ceiling, exclaimed: “Thou art the man!” Details of the casting of a great lens came next. It was twenty-four feet in diameter, and weighed nearly fifteen thousand pounds after it was polished; its estimated magnifying-power was forty-two thousand times. As he saw it safely started on its way to Africa, Sir John “expressed confidence in his ultimate ability to study even the entomology of the moon, in case she contained insects upon her surface.” Thus ended the first instalment of the story. Where had the _Sun_ got the _Journal of Science_ supplement? An editorial article answered that “it was very politely furnished us by a medical gentleman immediately from Scotland, in consequence of a paragraph which appeared on Friday last from the Edinburgh _Courant_.” The article added: The portion which we publish to-day is introductory to celestial discoveries of higher and more universal interest than any, in any science yet known to the human race. Now indeed it may be said that we live in an age of discovery.
