The pimples or eruptions will gradually disappear when the causes are removed, and the same rule will apply to eczema or any chronic form of skin irritation. The patient should first be put upon a short fast of two or three days' duration, and caused to perspire freely each day for an hour or so. This can be accomplished by the aid of the Turkish bath, but preferably by exercise. On the first day the fast should be broken by taking either the juice of such fruits as plums, peaches, apples, grapes, and pears, or the juice of cantaloup and watermelon. DIET FOR DIS-EASES OF THE SKIN The diet should be gradually broadened by the addition of green salads, uncooked carrots, onions and turnips, and a limited quantity of such cooked vegetables as spinach, asparagus, squash, fresh corn, green peas or beans when in season. Later, the diet should be confined mainly to egg whites, skimmed milk, nuts, sweet fruits, salads, fresh green vegetables, including a very limited quantity of sugar and coarse cereals, two or three times a week. DIET FOR CHRONIC ECZEMA In extreme and chronic cases of eczema the diet should be confined entirely to green salads, sweet fruits, fresh vegetables, and about two ounces of olive-oil daily, feeding the body always somewhat below its normal requirements as indicated by hunger. Under this diet and regimen the patient will, of course, lose weight and possibly strength, but the body will so completely make use of all nutrition and the elimination of all waste will be made so completely, through the excretory channels, that the dis-ease will gradually disappear, owing to the removal of its primary causes. For "Sweet Fruits," see Lesson VIII, p. 313. APPENDICITIS There are three large colons in the intestinal tract which form an inverted U, the "ascending," "transverse," and "descending" colons. The descending colon is situated on the left side, its lower part opening into the rectal cavity. The ascending colon, located on the right side, connects with the small intestines, while the transverse colon goes across at a point opposite the navel, connecting the two.
