Inedited Correspondence of Goethe and Schiller.--By many friends of German literature it will be remembered that Goethe, during his life, carefully preserved a particular portion of his papers and letters, which he in 1827 transferred to the government of Weimar, on the condition that the box in which they were contained should not be opened until the present year. The 17th of May was the date fixed upon, and in accordance with the will of the deceased poet, his heirs and those of his brother poet Schiller were on that day judicially summoned to Weimar to witness the opening of the case. Of Schiller's descendants there were present on the occasion, his eldest son and eldest daughter, and the widow of Ernst von Schiller. Goethe was represented by his daughter-in-law and his two grandsons, Wolfgang and Walther, who came from Vienna, their present place of residence, for the purpose. Schiller's eldest son is chief inspector of forests in Wurtemberg. Madame de Junot and Frau von Goethe were also present. The box on being opened was found to contain a full correspondence between Schiller and Goethe, ready arranged for the press. A codicil in Goethe's will provides for their publication. Most of the letters, all of Schiller's in fact, are autograph. * * * * * The Countess Ossoli, (Margaret Fuller,) we learn from the _Tribune_, will be in New York about the 20th of the present month. Her work on Italy will be given to the press immediately after her arrival. * * * * * Dr. Hoefer against Dr. Layard.--Dr. Hoefer, a well-known _savant_ in France and Germany, has astonished the Parisians by the publication of a work in which he boldly denies the authenticity of the ruins of Nineveh. Even admitting, he says, that the ruins of Nineveh remain, it is impossible that they can be in the place which Dr. Layard has explored; and, moreover, the Assyrian-like sculptures and inscriptions found in the supposed Nineveh, were the work of a later, and a different people, who had the affectation of imitating Assyrian taste. * * * * * Both Rogers and Wilson, it is said, have declined the laureateship. Referring to the office, the _Daily News_ has a very prosy simile: "A dog, of any sense or self-respect, with a tin-kettle tied to his tail, acutely feels the misery and degradation of the music he is compelled to make. What the tin-kettle is to the dog, the yearly Ode is to the muse. The board, if you please, but not the annoyance and irritation of the jangle." * * * * *
