This is of first importance as a general renovator of vital action. The secretion of gastric juice is, under ordinary circumstances, proportionate to the amount of nourishment which the system is prepared to assimilate. Exercise creates a demand for food, and so stimulates both assimilation and secretion. The best forms of exercise are those which will secure the most uniform activity of the several parts of the muscular system. Riding, walking, rowing, and especially horseback riding, are to be recommended as excellent. Gymnastic exercises and the judicious use of the "health lift" are also good; and for persons who from lack of time, or other cause, cannot adopt the other methods, these may be considered as almost indispensable. Such exercises as running, jumping, base-ball playing, "walking matches,"' and other violent exercises, cannot be recommended. Trapeze exercises must also be discountenanced on the same grounds. Agriculture, especially the raising of small fruits and the cultivation of flowers, cannot be too highly recommended as forms of exercise for dyspeptic patients. For that large class of sallow-skinned, weak-backed, dyspeptic young ladies who have been made dyspeptics by idleness and too much "coddling" by fond mothers, who sacrifice themselves to the monotonous drudgery of the cook-stove and the sewing-machine, and their daughters to sentimental idleness and fashionable piano-thrumming,-for the indigestion of these poor victims of mistaken maternal care, the varied exercise necessitated by domestic labor is a most admirable panacea. And for the gaunt, hollow-cheeked, sunken-eyed, slab-sided, cigar-worshiping young man whose chief occupation is cultivating a mustache, smoking cigarettes, and swinging a gold-headed cane, a little wholesome experience in earning a subsistence by the sweat of the brow, instead of leaning upon rich relatives, will prove a specific for "softening," which begins in the brain and extends to every part of the system.

Exercise before breakfast, while excellent for some, cannot be too much condemned for others. Persons who suffer with "goneness," "faintness," "sinking," and allied pains when the stomach is empty, and especially in the morning, must avoid exercise to any considerable extent before eating. Disregard of this rule occasions loss of appetite and weakening of digestion. Persons who are very weak must also avoid exercise before eating in the morning.

As before remarked, only gentle exercise can be taken soon after eating, or immediately before, without injury. Persons who feel a con stant "sinking" or weakness in the stomach and bowels will derive benefit from wearing about the body a broad band of flannel.
