Dr. William T. Cathell, of Baltimore, several years since recommended these waters to bring down one's weight. Of the French Vichys, he recommends the Grande Grille and the imported Kissingen. The artificial waters we get in siphons appear to do as well, and so do those prepared from the effervescing salts of Kissingen and Vichy on the market. Cathell recommends a full glass of Kissingen a half-hour after each meal one day; and the next day, in the same way, a glass of Vichy. Keep this up from day to day. If the patient loses more than two pounds per week in weight, take a small glass, or avoid the midday glass. If he loses less than two pounds per week, add the juice of half a lemon to each glass of Kissingen, or a teaspoonful of aromatic spirit of ammonia to each glass of Vichy. It is not necessary to restrict the diet, but cut down somewhat alcoholics, starch, sugar, and fats, if given to consuming large quantities of them. In other words, avoid overeating and excesses at the table. Sleep on an empty stomach as near as possible, so that some of the surplus fat may be burned up as fuel while the person sleeps. Take plenty of outdoor exercise to promote tissue oxidation. Another way is to take a glass of Vichy before breakfast and a glass of Kissingen at bedtime. Sipping from three to five glasses through the twenty-four hours is another way, alternating Vichy and Kissingen. Taking the waters may be kept up for six months or longer. This is said to be a revival somewhat of the Daucel system, giving sodium bicarbonate with tartaric acid and water in the effervescing state. There is no doubt the taking of these waters, curtailing somewhat the diet as to sweets and starches and fats, and taking plenty of outdoor exercise, does bring down the bodily weight in many cases and probably is a fairly safe method.
