Abstract : A study was made of the steel shot used as ballast in the bathyscaph TRIESTE, to compare the type procured in Italy with that available in the United States. Tests indicated that the 0.079-inch-diameter steel shot obtainable in the United States will function as effectively as the Italian shot, under similar conditions.
