2. The relief of the gastro-intestinal catarrh in gouty dyspeptics may often be accomplished solely by dietetic restrictions and by the aid which may be given to primary digestion. It is often necessary, however, to direct some special medication toward the relief of the catarrhal lesion. The circumstances which demand this special medication are the existence of portal congestion, the result of functional derangement, or of chronic atrophy of the liver, or of chronic diffuse or interstitial nephritis, or of cardiac disease. The hydragogues, such as calomel, podophyllin, colocynth, and other vegetable cathartics, with the salts of sodium and magnesium, constitute the most common and efficient means of relieving portal congestion, whether it arise from temporary functional derangement or from organic disease. The renown of some of the more famous mineral springs in relieving the miseries of gouty sufferers is due mainly to the relief of portal congestion and the washing away of the catarrhal mucus which obstructs the process of primary food transformation and absorption. This is especially true of the sulphate of sodium waters, like those of Carlsbad, Marienbad, Friedrichshall, Pullna, and Hunyadi János. While the value of these waters in chronic gout is unquestionable where their use is properly regulated, there is good reason to believe that their long-continued employment is often harmful by relaxing the mucous membrane, and thereby tending to aggravate the condition they are given to relieve. This is markedly true of their use in weak and anæmic persons. For these the milder magnesian waters, such as those of Kissengen, Hombourg, Wiesbaden, and Saratoga, are to be preferred. 3. The augmentation of food-oxidation may be accomplished in a large degree by regulation of the diet and by out-door exercise. The {132} regulation of the diet according to the occupation and habits of life is a point of primary importance in securing proper blood-elaboration. My experience leads me to believe that the evil consequences of in-door occupations and sedentary habits are most common in those who live upon a diet composed largely of starchy and saccharine foods, and that a diet in which animal foods and fats predominate is best suited to indoor workers, whether they be engaged in mechanical or intellectual labor.
