Dr. Goadby, who has recently delivered in this city a very interesting course of lectures upon insects, has a most valuable series of dissections, prepared at a cost of labor which would seem almost incredible. The anatomy of a caterpillar, comprising three distinct preparations—its nervous system, its organs of respiration, and its organs of nutrition—occupied the undivided labor of thirteen weeks, at the rate of fourteen hours a day.

Gen. Henderson, who was on trial at New Orleans on the charge of being implicated in the Cuban invasion, has been discharged, the jury being unable to agree. The District Attorney therefore entered a nolle prosequi in the case of Governor Quitman and all others under indictment.

The new Leipzig Deutsches Museum (Westermann Brothers, New York,) promises to meet the want which we have for some time found it impossible to supply, of a German literary Magazine. In the recent revolutionary storms this class of periodicals generally went down, so that for information as to the working of the German mind we have been forced to rely upon chance notices in the political journals, or trust to foreign sources. It is published semi-monthly. Its cost in Leipzig is 12 Thalers; and is furnished here for the same number of dollars.

Under the title of Causeries du Lundi M. St. Beauve has just put forth a volume of sketches of contemporary French authors, which almost forces us to envy the happy land blessed with such a number of men, the worst of whom exceeds our ideas of any attainable height of perfection. A word or two of criticism is awarded to Lamartine, but too bland to wound even the vanity of the gentle Alphonse. But Girardin and Villemain, Cousin and George Sand, Thiers and Montalembert receive a most unqualified apotheosis. The title of "Monday Chat" simply indicates that the book is made up of articles which appeared on Mondays in the Constitutionnel newspaper.

Pictures by the "Old Masters," as all the world knows, are manufactured as readily, and almost as extensively, as calico. It is not, however, so well known that "old and rare editions" of books are produced nowadays. The passion of book-collectors has given a new impulse to this business. Within a few months the beautiful editions of the classics of the Elzevirs and the Stephens have been reproduced with wonderful skill. In paper, type, ink, and binding there is no perceptible difference; while the precise air of antiquity desired is produced by chemical means.

M. Feuillet de Conches, a Parisian virtuoso, and great admirer of La Fontaine, has spent a vast sum in having printed for his own sole use a single copy of the works of the famous fabulist. It is illustrated in the most gorgeous style, by the first artists of the day; and is accompanied with notes and prefaces by the most eminent writers, and is a very miracle of expensive typography and binding.

Victor Hugo has published nothing for some years, having been paid by a publisher not to print. Report says that he will, at the close of his term, which soon expires, make amends for his long silence by issuing poems to the amount of three volumes, and romances to that of twelve.

A work by Origen, the celebrated Father in the Church, hitherto unknown, has been discovered and published by the librarian of the National Assembly—so M. Villemain announced at a recent meeting of the Académie des Belles Lettres at Paris. The work traces the heresies of the third century to the writings of the Pagan Philosophers, and throws new light upon ancient manners, literature, and philosophy.

In the album presented to the King of Bavaria by the artists of Münich, is an admirable composition by Hübner. It is an expression of the feelings of a large portion of Upper Germany. It represents a female prostrate upon the ground, with the arms crossed, the face entirely hidden, in an attitude of the deepest despair. The long hair floats over the arms, and trails along the ground. The whole figure is a mixture of majesty and utter abandonment. The simple title of the piece is—"Germania, 1850."
