Sec. 315. Chronical Diseases not coming within the Plan of this Work, I purposely forbear treating of any Kind of those tedious Cholics, which afflict some People for many Years: but I think it my Duty to admonish such, that their Torments being very generally occasioned by Obstructions in the _Viscera_, or different Bowels of the Belly, or by some other Fault, and more particularly in those Organs, which are intended to prepare the Bile, they should, 1, avoid with the greatest Care, the Use of sharp, hot, violent Medicines, Vomits, strong Purges, Elixirs, _&c._ 2, They should be thoroughly on their Guard against all those, who promise them a very speedy Cure, by the Assistance of some specific Remedy; and ought to look upon them as Mountebanks, into whose Hands it is highly dangerous to trust themselves. 3, They should be persuaded, or rather convinced, that they can entertain no reasonable Hope of being cured, without an exact Conformity to a proper and judicious Regimen, and a long Perseverance in a Course of mild and safe Remedies. 4, They should continually reflect with themselves, that there is little Difficulty in doing them great Mischief; and that their Complaints are of that Sort, which require the greatest Knowledge and Prudence in those Persons, to whom the Treatment and Cure of them are confided. __Chapter XXII.__ _Of the Iliac Passion, and of the Cholera-morbus._ __Sect.__ 316. These violent Diseases are fatal to many Country People, while their Neighbours are frequently so ignorant of the Cause of their Death, that Superstition has ascribed it to Poison, or to Witchcraft. Sec. 317. The first of these, the _Miserere_, or Iliac Passion, is one of the most excruciating Distempers. If any Part of the Intestines, the Cavity of the Guts is closed up, whatever may have occasioned it, the Course or Descent of the Food they contain is necessarily stopped; in which Case it frequently happens, that that continual Motion observed in the Guts of a living Animal dissected, and which was intended to detrude, or force their Contents downwards, is propagated in a directly contrary Manner, from the Guts towards the Mouth.
