A fluid flowing from the trachea of fetal lambs was collected and its surface active components were concentrated by foaming. The foam showed a greater concentration of active phospholipids and a greater surface stability than did the crude lung fluid. The residuum after foaming had less phospholipids and less surface stability than the crude lung fluid.
