The John Thomas case.
--The case of the negro, John Thomas, who was brought to Richmond from New York, has been bauled up by the Black Republicans. The New York correspondent of the Philadelphia Ledger says:‘ In the Court of Oyer and Terminer, this morning, Judge Mullen addressed the grand jury on the subject of the habeas corpus of the fugitive slave, John Thomas. Some men, said the Judge, had seized this person in the street, and taken him, by force, before one of the U. S. Courts, and from there he was conveyed to Virginia.
His Honor went on to say that it was due to the law of the land that this case be not passed by as a trifle; if a colored man be so carried off, a white man could be served in the same manner; and although, in the present disturbed state of the country, he did not like to allude to such a topic, still it was necessary to preserve the dignity of the law and the rights of individuals. His Honor would not state whether the United States Marshal of this District was or was not a party to the transaction; but it was certain that the legal forms had been complied with, and he hoped that the grand jurors would take such action in the premises as they deemed proper to punish the authors of such an outrage.
