It is very common to see Children in the Country (and they are seldom more than Children who have it so very gently) run about in the open Air, through the whole Course of this Disease, and feeding just as they do in Health. Even those who take it in a somewhat higher Degree, commonly go out when Eruption is finished, and give themselves up, without Reserve, to the Voracity of their Hunger. Notwithstanding all this Neglect, many get perfectly cured; though such a Conduct should never be proposed for Imitation, since Numbers have experienced its pernicious Consequences, and several of these Children have been brought to me, especially from _Jurat_, who after such Neglect, in the Course of the mild and kindly Sort of this Distemper, have contracted Complaints and Infirmities of different Kinds, which have been found very difficult to subdue. Sec. 211. This still continues to be one of these Distempers, whose Danger has long been increased by its improper Treatment, and especially by forcing the Patients into Sweats; and it still continues to be increased, particularly among Country People. They have seen Eruption appear, where the Patient sweats, and observed he found himself better after its Appearance: and hence they conclude that, by quickening and forcing out this Eruption, they contribute to his Relief; and suppose, that by increasing the Quantity of his Sweats, and the Number of his Eruptions, the Blood is the better cleared and purified from the Poison. These are mortal Errors, which daily Experience has demonstrated, by their tragical Consequences. When the Contagion or Poison, which generates this Disease, has been admitted into the Blood, it requires a certain Term to produce its usual Effects: at which Time the Blood being tainted by the Venom it has received, and by that which such Venom has formed or assimilated from it, Nature makes an Effort to free herself of it, and to expell it by the Skin, precisely at the Time when every Thing is predisposed for that Purpose. This Effort pretty generally succeeds, being very often rather too rapid and violent, and very seldom too weak. Hence it is evident, that whenever this Effort is deficient, it ought not to be heightened by hot Medicines or Means, which make it too violent and dangerous: for when it already exceeds in this Respect, a further Increase of such Violence must render it mortal. There are but few Cases in which the Efforts of Nature, on this Occasion, are too languid and feeble, especially in the Country; and whenever such rare Cases do occur, it is very difficult to form a just and proper Estimation of them: for which Reason we should be very reserved and cautious in the Use of heating Medicines, which are so mortally pernicious in this Disease.
