I allude to such productions as the Arabian Nights, Sir Thomas More's Utopia, Bishop Berkeley's Adventures of Signior Gaudentio Di Lucca, Swift's Gulliver's Travels, De Foe's Robinson Crusoe, Bunyan's Pilgrim's Progress, and Lord Erskine's Armata, besides numerous others of a similar character but of a less celebrated reputation. Among this class of extraordinary fictitious narratives and supposed discovery, may be placed the renowned Moon Hoax, by Richard Adams Locke. When it first made its appearance from day to day in one of the morning papers, the interest in the discovery was intense, so much so that the circulation of the paper augmented five fold, and in fact, was the means of giving the journal a permanent footing as a daily newspaper. Nor did this multiplied circulation of the paper satisfy the public appetite. The proprietors of the journal had an edition of 60,000 published in pamphlet form, which were sold off in less than one month; and of late this pamphlet edition has become so scarce that a single copy was lately sold at the sale of Mr. Haswell's Library for $3.75. The book is still in demand. As an instance of this the following will give some idea at what pains and cost some will go to procure it. I lately had a letter from a Gentleman residing in Wisconsin, making inquiry if I had such a book, he further informed me that his attention had been called to my book establishment in consequence of having sent to the _Sunday Times_, published in this city, the following query, "Can you inform me if such a book can be procured, and if so where, as 'The celebrated Moon Hoax?'" The answer was that if it could be procured at all, it would be at 85 Centre Street, New York. By this circuitous method, this dilligent far-west bookcollector procured his copy of the "Moon Hoax" to his great satisfaction. August 1, 1859. PUBLISHER.

In this unusual addition to our Journal, we have the happiness of making known to the British public, and thence to the whole civilized world, recent discoveries in Astronomy which will build an imperishable monument to the age in which we live, and confer upon the present generation of the human race a proud distinction through all future time. It has been poetically said, that the stars of heaven are the hereditary regalia of man, as the intellectual sovereign of the animal creation. He may now fold the Zodiack around him with a loftier consciousness of his mental supremacy.
