A return of appetite, of sleep, of chearfulness, are the necessary consequences of motion; but the precaution should be observed, of not taking any thing of a violent motion immediately after a meal, and not to eat while warm from exercise; which should be taken before a meal, with allowance of some moments of rest before the sitting down to it. _EVACUATIONS._ The evacuations are apt to be disordered along with the other functions, and their disorder increases that of the whole machine; it is then of importance to give attention thereto, in order to the earliest remedy. The evacuations which principally require observation are, the stools, the urines, the perspiration, and the saliva. The best way to keep them in due order, or to bring them to the point at which they ought to be at, is to govern one’s self by those precepts which I have laid down on the other objects of regimen: when those are heedfully attended to in practice, the evacuations, whose greater or the less regularity is the barometer of the better or worse state of digestions, proceed regularly enough. That evacuation which it is of the most importance to favor, as being the most considerable, is perspiration, which very easily goes out of order, in weak persons. It may be aided by having the skin very regularly rubbed with a flesh-brush, or a flannel; but when it is very languishing indeed, there is not a surer way to restore it, than to put the whole body immediately into woollen covering. And yet care should be taken to avoid too warm a dress, for fear of sweating, which is always detrimental to perspiration; the forced strainers remain the weaker, and perform their functions the worse: too cool a dress is also to be shunned, as that is an enemy equally to all cutaneous evacuations. The part which every person, and especially the weak, ought to keep the warmest, is the feet. This easy precaution would never be neglected, if the importance of it to the preservation of the whole machine was sufficiently known. Frequent catching cold of the feet disposes to the most terrible chronical diseases. There are many on whom it immediately produces bad effects. But those especially who are subject to disorders of the breast, to cholics, or to obstructions, cannot too much guard against these dangers. Those priests who used to walk bare-footed on the pavement of the temples were often attacked with violent cholics.
