Now the most healthy person in the world, would ere long have an acid stomach, as well as weakened lungs, who should undertake to live in this way; how much more a person who has long been feeble, especially in his lungs, nervous system, and even his digestive system, for that was active rather than strong.
Indeed, there are many circumstances which favor the belief that he burned himself out by excess of stimulus, or, in chemical language, by excess of carbon. His thoughts seem to have been very largely on eating. It will be seen by the extracts I have made from his letters, that after speaking on any other needful topic, he would soon get back to the subject of eating. Observe, too, he says he feels no temptation to eat between his meals; but why? First, doubtless, because he eat to the full at his regular meals; and secondly, because the food was mostly, if not always, set away out of his reach.
Another thing deserves consideration. Not only was he, but his friends also, inclined to the opinion that he would not, and perhaps could not, hurt himself on such things as plain dry bread; but they also appeared to believe, practically, at least,—and the belief is very common,—that the use of bread would atone for other transgressions. Thus, suppose he were to have, for once, a rich pudding to eat, or some baked beans, or sweetened rice pudding,—which, as you know, are of themselves very pure nutriments,—set before him, and he were to eat to the full, till the question should begin to arise in his own mind, whether he had not gone too far, it was apt to be thought, or rather felt, that an addition of plain bread, or some fruit, or a few cold potatoes, or some other vegetable, would be a correction for the preceding excess. Such, I say, is the virtue which, by a kind of tradition, is awarded to coarse and plain food, and to fruits, and even nuts. I know, indeed, that this idea would hardly be defended in so many words; still, it is practically entertained.
To make plainer a great dietetic error, I will explain my meaning. It is believed, for example, that a pound or two of greasy baked beans would not be so likely to hurt a person, if a little bread or fruit or potatoe or sauce were eaten after them, as if eaten alone,—a belief than which none can be more unfounded or dangerous.
One more proof that Samuel was constantly inclined to excess in eating, is found in the fact that there was a continual tendency, in his stomach, to acidity, which was best relieved by a day of entire abstinence; and the same might be said of a tendency to relaxation of the bowels, and its correction. In short, if there be a plain truth fairly deducible from the facts in the case, it is that he was destroyed by a carbonaceous nutriment in too great proportion for his expenditure.
It may have been feared by his friends, that he yielded, at this period, to other propensities. Indeed, one letter which I received after his death, more than intimated all this. The remark alluded to was as follows:—"I have had the fear that there was something unexplained about his case, as you say you once had." For various reasons, I am inclined to believe that the indulgence referred to had little to do with his comparatively sudden death. His whole soul was pivoted on that great central organ, the stomach. For this he lived, and for this, probably, he died.
My own principal error, in relation to the case, was, in suffering him to go upon the farm with such unintelligent, though well-intentioned teachers. Lord Bacon and others have said, "A little knowledge is a dangerous thing;" and in nothing is the remark more applicable than to the first or pioneer knowledge of people on hygiene. From the very nature of the case it must be so. I ought either to have protested against the farm, in toto, or given such minute instructions that they could not have been easily mistaken. But I had my reasons, at the time, for the course I took, and I thought them quite sufficient. How easy it is, in this world, to find cause for misgivings!
