There is one circumstance which I must not omit, because it is full of admonition and instruction. I have elsewhere stated that, twenty-three years ago, I had incipient phthisis. Of this fact, and of the fact that there were considerable inroads made by disease on the upper lobe of the right lung, I have not the slightest doubt. The symptoms were such at the time, and subsequently, as could not have been mistaken. Besides, what was, as I conceive, pretty fully established by the symptoms which existed, is rendered still more certain by auscultation. The sounds which are heard during respiration, in the region to which I have alluded, leave no doubt on the minds of skillful medical men, of their origin. Still I doubt whether the disease has made any considerable progress for many years. But, during the winter of 1837-8, my employments became excessively laborious; and, for the whole winter and spring, were sufficient for at least two healthy and strong men. They were also almost wholly sedentary. At the end of May, I took a long and rather fatiguing journey through a country by no means the most healthy, and came home somewhat depressed in mind and body, especially the former. I was also unusually emaciated, and I began to have fears of a decline. Still, however, my appetite was good, and I had a good share of bodily strength. The more I directed my attention to myself, the worse I became; and I actually soon began to experience darting pains in the chest, together with other symptoms of a renewal of pulmonary disease. Perceiving my danger, however, from the state of my mind, I at length made a powerful effort to shake off the mental disturbance--which succeeded. This, together with moderate labor and rather more exercise than before, seemed gradually to set me right. Again, in the spring of 1848, after lecturing for weeks and months--often in bad and unventilated rooms and subjecting myself, unavoidably, to many of those abuses which exist every where in society, I was attacked with a cough, followed by great debility, from which it cost me some three months or more of labor with the spade and hoe, to recover. With this and the exceptions before named, I have now, for about twenty years, been as healthy as ever I was in my life, except the slight tendency to cold during the winter of which I have already taken notice. I never was more cheerful or more happy; never saw the world in a brighter aspect; never before was it more truly "morning all day" with me. I have paid, in part, the penalty of my transgressions; and may, perhaps, go on, in life, many years longer.
