The air cy'linder carries, two inches 1' from its open base, two shelves, one on each side, on which are placed ballast-weights for the purpose of lowering the center of gravity, and thus maintaining the steadiness of the apparatus. Both shelves and weights are perforated to avoid resistance of water. As the area of the top of the air chamber is just fifty square inches, atmospheric pressure upon it equals, in round num bers, 750 pounds. With the ballast upon its shelves, the cylinder weighs ten pounds, giving an excess pressure of fi atmosphere. Weights are furnished in two sizes, in the shape of rectangular blocks of iron 45 by 2 inches surface, and about inch and 1 inch thick, respectively.
