I do not of course undertake to say that he owed his recovery from his long sickness, above described solely to drinking cold water, there are so many other circumstances to be taken into the account, in settling all questions like this, that such an assertion would be hazardous, not to say foolish. His fever at the time of making his experiment, had already passed away; and having great tenacity of life, it was but reasonable to expect nature would ere long, rally, if she _could_ rally at all. It is also worthy of remark, that though his physician was one of those men who place their chief reliance on the medicine they give, rather than on the recuperative powers of the system, yet to his credit be it said, he had in this instance departed from his usual routine, and given comparatively little. Perhaps we may explain the phenomenon of his recovery, as follows: nature long oppressed, yet by rest partially restored to her wonted energy, was now ready to rally as soon as she could get the opportunity; this the moderate draughts of water by their effects on the circulation enabled her to do; then, too, one consideration which I forgot to mention in its place, deserves to be noticed. When the sick man began the use of water, he laid aside (without the knowledge of his physician) most of what pills and powders and tinctures were prescribed him. And finally he had great faith in the water, as you have already seen; whereas he had lost all faith in drugging and dosing. And the efficacy of faith is almost sufficient in such cases, to work a cure, were this our only reliance. Of this we shall have an illustration in Chapter LXXVI. But though the water, as I now fully believe--and as I more than half believed when I heard of the facts at the time,--was fairly indicated, there is great hazard, in such circumstances in its use. Had this gentleman taken a large draught at first, or had he swallowed more moderate draughts with great eagerness, and a quick succession, it might have produced an ill effect; it might, even, have provoked a relapse of his dysentery and fever. Many a sick patient in the same circumstances, would have poured the cooling liquid into an enfeebled throat and stomach without the least restraint. And why did not he? I will give you one reason. He was early taught to govern himself. He told me, when eighty-eight years of age, he had made it a rule, all his life long, never to eat enough, but always to leave off his meals with a good appetite. He did not indeed, follow out with exactness the rule of the late Amos Lawrence: "Begin hungry and leave off hungrier," but he came very near it. He managed so as always to have a good appetite, and never in the progress of more than fourscore years, whether by night or day, to lose it. Such a man, if his mind is not too much reduced by long disease, can be safely trusted with cold spring water, even during the more painful and trying circumstances of convalescence from acute disease.
