The fragments from the acetabulum are indicated bythe clots. The head of the femur is uninjured. This skiagraph wasmade on an 8x10 plate, with a compression diaphragm and a me-dium vacuum tube energized by a 24-inch coil with an electrolyticinterrupter, in twenty seconds. It would have required from twoto five minutes to have made the same skiagraph with a static ma-chine, provided the machine had been in perfect order, with otherconditions equally favorable. Only the induction coil or trans-former can be relied upon to produce satisfactory skiagraphs.
