Mae'r toriad yn darllen fel a ganlyn: "On Tuesday last, John Phillips and Wm. Lewis, of Hakin, near Milford, fishermen, having set their trammel net in the mouth of the little creek they called Sandy Haven, about two miles below Milford, they, on the ebb of the tide, proceeded to haul their net, when they discovered a large fish had greatly injured it, having entangled itself, and was nearly dead from beating against a rock. The fish appears to be a species of the white shark. Its dimensions were as follows: - Length from the tip of the nose to the extremity of the tail, 3ft. 9in.; circumference at the middle 4ft. 7in.; with a strong fin on the back about 18 inches long, and horizontal tail two feet and a half deep; it had four rows of sharp teeth, about an inch long, in the lower, and two rows in the upper jaw, and weighed about four hundred weight."
