Among the most common consequences of improper feeding and neglect of exercise is indigestion, attended by its usual concomitant, constipation. If moderate starvation does not soon restore the stomach, care must be taken that the liver is acting properly, the faeces being watched to see if they are of a proper color; if they are not, small doses of calomel or blue pill will be required: (1), (2), or 13). If, on the contrary, the liver acts properly, yet the stomach is out of order, recourse may be had to the stomachic bolus (59), or to the draught (60), which will very seldom fail, if aided by proper management. It should, however, never be forgotten that medicine is of no use, unless, at the same time, the diet is attended to, and sufficient exercise given. In cases of indigestion, it is particularly necessary to change the food every third or fourth day.
