Fatal Occurrence . – The Lexington Observer of the 22d inst. says – “we learn by a gentlemen, that, on Monday last Mr. John R. Scott of Jessamine county, was shot through the head with a pistol, and expired in a few hours afterwards. The circumstances have not been fully related to us, but it appears that a recontre had taken place, or was about to take place, between two individuals, January and Reese, and that the deceased interfered to put a stop to it, when he was unintentionally shot by Reese, who perhaps intended to shoot his antagonist, January. The deceased was highly respectable.”
