This Fifth and Last Class contains all such infected Persons, as without perceiving any Emotion, or there appearing any Trouble or Lesion of their natural Function, have Buboes and Carbuncles, which rise by little and little, and easily turn to Surpuration, becoming sometimes scirrhous, or which is more rare, dissipate insensibly, without leaving any bad Effect behind them; so that without any loss of Strength, and without changing their manner of Living, these infected Persons went about the Streets and publick Places, only using themselves a simple Plaister, or asking of the Physicians and Surgeons such Remedies as are necessary to these sorts of suppurating or scirrhous Tumours. The Number of the infected contained in the two last Classes, were so considerable, that one may affirm, without any exaggeration, that more than fifteen or twenty Thousand Persons were found in these sorts of Cases; and if the Distemper had not often taken this turn, there would not have been left in this City the fourth Part of its Inhabitants. We may very well admit a Sixth Class of such as we have seen perish without any Forerunner, or other manifest Hurt, than only a decay in Strength; and who being asked concerning their Condition, answered, that they were not sensible of any Disorder, which for the most part denoted a desperate Case, and an approaching Death; but the Number of these were very small in Comparison of such as made up the preceding Classes. Besides all these Observations, it has happened that amongst so great a Number of infected Persons, we have seen many particular Cases, wherein, contrary to our Expectation, and all the Appearance of Reason, the Sick have perished or recovered; but we are of Opinion that it would be useless to relate them here, and to give of them a long and tedious Account; being moreover persuaded that these Sorts of particular Events can serve as no sure Rule to form a Prognostick, or how to proceed in the like Distemper. It is therefore more proper to keep to the Observations we have made, and that the rather, since they are found conformable to those of our Collegues who have laboured in concert with us in this so painful and dangerous Work; and who have always professed to relate what they have seen and observed themselves, without suffering themselves to be prejudiced by all the Reports that a vain Credulity, a popular Superstition, the Boastings of Empericks, and the Greediness of making Profit by the publick Calamity, have spread through this City.
