I have referred to the fact that the most common causes of constipation, indigestion and other foul conditions of the alimentary canal favorable to the production of autogenetic poisons and their auto-infection, are such common and every-day matters, so familiar to almost every one that the victim, the parents and the physician feel no alarm of the coming danger for years. During these ignorant and innocent years the poison and filth were being absorbed, infecting the system with their morbific taint and lowering the quality of the blood and lessening its quantity, producing the state known as anemia. Associated with progressive anemia is mal-assimilation, improper nutrition, ebbing of the nervous and vital forces and the lessening of the secretory, excretory and digestive powers. By the time the poor victim is weighing fifteen to twenty-five pounds less than he ought to the symptoms of ill-health are sufficiently alarming to compel the sufferer to seek medical aid for disease of the stomach, bowels, liver, kidneys, lungs, etc. _Slow digestion_ is perhaps the most common form of functional disturbance of the stomach, due to an insidious auto-infection for years. The eyes and the skin begin to show the effect of the poisonous infection. The skin becomes dry, pale and muddy in color; has more or less annoying eruptions, and exhibits a jaundiced appearance. The body is ill nourished, the nervous system depressed, the blood impoverished, the memory failing, the general appearance languid, irritable, anxious. What a household picture this is to every one of the human family! But let us fill it out somewhat more fully. Note how the undue delay of food in the stomach occasions a sense of weight and oppression, the feeling beginning about an hour after a meal and continuing for hours, sometimes attended with fermentation and sometimes without it. At times there is a feeling of drowsiness due to the absorption of an excessive amount of the gases which distend the stomach and bowels, and this absorption is accompanied by pains in the stomach, head, between the shoulders and in the region of the heart. Sleep is disturbed by dreams, or one is awakened with a feeling of numbness and palpitation of the heart. At times the urine is scanty, strongly acid or high-colored. The tongue is more or less foul, with white or creamy coating. Now and then tasteless or saltish eructations occur. The appetite may be too good, or there is no appetite at all. Note the careworn expression, the wondering what to eat, what to drink or what remedy to take. So between much worse and some better, the trouble continues--both of body and mind.
