As long as the State of the Pulse is promising; Respiration or Breathing is free; the Brain does not seem to be greatly affected; while the Patient takes his Medicines, and they are attended with the Consequence that was expected; and he both preserves his Strength pretty well, and continues sensible of his Situation, we may reasonably hope for his Cure. As often as all, or the greater Number of these characterizing Circumstances are wanting, he is in very considerable Danger. The Stoppage of Perspiration is often mentioned in the Course of this Work. We call the Discharge of that Fluid which continually passes off through the Pores of the Skin, _Transpiration_; and which, though invisible, is very considerable. For if a Person in Health eats and drinks to the Weight of eight Pounds daily, he does not discharge four of them by Stool and Urine together, the Remainder passing off by insensible Transpiration. It may easily be conceived, that if so considerable a Discharge is stopt, or considerably lessened; and if this Fluid, which ought to transpire through the Skin, should be transfered to any inward Part, it must occasion some dangerous Complaint. In fact this is one of the most frequent Causes of Diseases. To conclude very briefly--All the Directions in the following Treatise are solely designed for such Patients, as cannot have the Attendance of a Physician. I am far from supporting, they ought to do instead of one, even in those Diseases, of which I have treated in the fullest Manner; and the Moment a Physician arrives, they ought to be laid aside. The Confidence reposed in him should be entire, or there should be none. The Success of the Event is founded in that. It is his Province to judge of the Disease, to select Medicines against it; and it is easy to foresee the Inconveniences that may follow, from proposing to him to consult with any others, preferably to those he may chuse to consult with; only because they have succeeded in the Treatment of another Patient, whose Case they suppose to have been nearly the same with the present Case. This were much the same, as to order a Shoemaker to make a Shoe for one Foot by the Pattern of another Shoe, rather than by the Measure he has just taken.
