The following is an extract from a private letter dated Barrancas, Fla., Oct. 5, 1864:
"Gen. ASBOTH, who was so seriously wounded at Marianna, Fla., was taken yesterday noon from his immovable position to a more comforable one. His arm, with the double fracture, was placed in an angular splint, and the other wound was properly examined and dressed.
The General, though he took chloroform, was yet fully conscious, and conversed fluently and in a joking manner with those around him, evidently not suffering much pain under the operation. Among the medical officers in attendance was Dr. PALMER, the Fleet Surgeon, Navy Surgeon TURNER, rebel Admiral BUCHANAN's Fleet Surgeon CONRAD and others. Dr. PALMER is confident that the arm can be saved and the General soon brought again into the saddle. The General himself is in the best of spirits, continuing to attend to his official duties, and resorting at times to the diversions of the chess board, which he plays with equal fondness and skill."
