Mr. CRALLE, the intimate friend and confidential secretary of Mr. CALHOUN, is engaged in preparing for publication the Works of the great southern statesman, to be accompanied by a Biography. The whole will be comprised, probably, in six octavo volumes. The first volume, which is now printed, and will soon be ready for publication, is occupied by an elaborate disquisition on Government, and a Discourse on the Constitution and Government of the United States. These treatises have always been spoken of as the "great work" of Mr. Calhoun's life, setting forth in a systematic manner his views upon the philosophy of civil government. The treatises were commenced many years since, but never received the final revision and correction which the author intended to bestow upon them. The Complete Works of ALEXANDER HAMILTON are now in course of publication by C. S. Francis & Co. They are mainly printed from the manuscripts purchased by Congress, under the direction of the Library Committee. The collection will extend to seven octavo volumes. It has long been suspected that colors were depicted on Daguerreotype plates, if they could only be developed. Mr. HILL, of this State, announces that he has succeeded in producing pictures in which every tint and shade is accurately represented. We are assured by one of our most eminent operators, one of the very few who have seen the pictures, that there is no doubt of the fact. The inventor as yet keeps his process a secret, though we understand that he is preparing a memoir in relation to it. BAYARD TAYLOR'S El-Dorado has been translated into German by C. Hartman, author of a Geographical and Historical Description of California. Mr. SAMUEL MAVERICK, of Pendleton, S. C., who is still living, assisted in packing the first bale of cotton ever sent from the United States to Liverpool. It was sent in the seed, and the consignee informed his South Carolina correspondent that the article was useless, could not be sold, and advised him to send no more. 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. EUROPEAN.
