H. de Veuve, of Galveston, Texas, lias invented an improved apparatus for lowering and detaching life and other boats. There are three chains-attached to the sides ami bottom of a boat, and terminating in a piece of iron having a head worked on to it. This head is grasped by a pair of callipers suspended by suitable tackle from the ship. When the weight of the boat is on the callipers, it holds them together, but the moment it % touches the water and is fairly afloat, the cal- lipers release themselves, and leave the boat f quite free. A patent was obtained this week
