This electrode is made largeand applied snugly to the surface of the abdomen, in order tothoroughly diffuse the current as it passes through the skin, andprevent any destructive effects at that point. The clay electrode 334 PRACTICAL ELECTRICITY IN MEDICINE AND SURGERY. of Apostoli (Fig. 241) is somewhat awkward to handle, andvarious modifications of it have heen suggested or employed. Fig. 242 shows Goelets clay electrode, which is more cleanlyand less inconvenient to handle. The clav is first worked to the
