The first is, Where and how is food made into gas while in the body? If you will listen to a dyspeptic after eating you will wonder where he gets all the wind that he rifts from his stomach, and continues for one or two hours after each meal. That gas is generated in the stomach and intestines, and we are led to believe so because we know of no other place in which it can be made and thrown into the stomach by any tubes or other methods of entry. Thus by the evidence so far the stomach and bowels are the one place in which this gas is generated. Now comes question two: As I have spoken of the stomach that generates and ejects great quantities of gas for a longer or shorter time after meals, this class of people have always been called dyspeptics. Another class of the same race of beings stand side by side with him, without this gas generating. He, too, eats and drinks of the same kind of food, without any of the manifestations that have been described in the first class. Why does one stomach blow off gas continually, while the other does not? is a very deep, serious and interesting question. As number two throws off no gas from the stomach after eating, is this conclusive evidence that his stomach generates no gas? Or does his stomach and bowels form gas just as fast as No. 1? and the secretions of the stomach and bowels take up and retain the nutritious matter and pass the remainder of the gas by way of the excretory ducts through the skin? If the excretory ducts take up and carry this gas out of the body by way of the skin, and he is a healthy man, why not account for No. one's stomach ejecting this gas by way of the mouth, because of the fact that the secretions of the stomach are either clogged up or inactive, for want of vital motion of the nerve terminals of the stomach. Another question in connection with this subject: Why is the man whose stomach belches forth gas in such abundance also suffering with cold feet, hands and all over the body, while No. 2 is quite warm and comfortable, with a glow of warmth passing from his body all the time? With these hints I will ask the question: What is digestion? CHAPTER VI. THE LYMPHATICS.
