In regard to other complaints, I may say still more. Of rheumatism, I have scarcely had a twinge in twelve or fourteen years. My eruptive complaint is, I believe, _entirely_ gone. The weakness of my eyes has been wholly gone for many years. Indeed, the strength and perfection of my sight and of all my senses, till nearly fifty years of age--hearing perhaps excepted, in which I perceive no alteration--appeared to be constantly improving. My stomach and intestines perform their respective duties in the most appropriate, correct, and healthful manner. My appetite is constantly good, and as constantly improving;--that is, going on toward perfection. I can detect, especially by taste, almost any thing which is in the least offensive or deleterious in food or drink; and yet I can receive, without immediate apparent disturbance, and readily digest, almost any thing which ever entered a human stomach--knives, pencils, clay, chalk, etc., perhaps excepted. I can eat a full meal of cabbage, or any other very objectionable crude aliment, or even cheese or pastry--a single meal, I mean--with apparent impunity; not when fatigued, of course, or in any way debilitated, but in the morning and when in full strength. It is true, I make no experiments of this sort, except occasionally _as_ experiments. In my former statements I gave it as my opinion that vegetable food was less aperient than animal. My opinion now is, that if we were trained on vegetable food, and had never received substances into the stomach which were unduly stimulating, we should find the intestinal or peristaltic action quite sufficient. The apparent sluggishness of the bowels, when we first exchange an animal diet for a vegetable one, is probably owing to our former abuses. At present, I find my plain vegetable food, in moderate and reasonable quantity, quite as aperient as it ought to be, and, if I exceed a proper quantity, too much so. I have now no remaining doubts of the vast importance that would result to mankind, from an universal training from childhood, to the exclusive use of vegetable food. I believe such a course of training, along with a due attention to air, exercise, cleanliness, etc., would be the means of improving our race, physically, intellectually, and morally, beyond any thing of which the world has yet conceived. But my reasons for this belief will be seen more fully in another place. They are founded in science and the observation of facts around me, much more than on a narrow individual experience.
