I was called to a Girl the first Day of her Seizure, who breathed without any Difficulty, her Warmth was moderate and natural, her Inwards free from glowing and Pain, and her Pulse not unequal or irregular; but, on the contrary, all Things genuine and well, as if she had ailed nothing; and indeed I was rather inclined to think she counterfeited being sick, than really to be out of Order, until examining her Breast, I found the certain Characters of Death imprinted in many Places; and in that following Night she died, before she her self, or any Person about her, could discern her otherwise out of Order. Some time after I visited a Widow of Sixty Years of Age, whom I met with at Dinner, where she had eat heartily of Mutton, and filled besides her Stomach with Broth; after I had enquired into several Particulars relating to her Health, she affirmed her self to have never been better in her Life, but upon feeling her Pulse, I perceived it to intermit, and upon examining her Breast, I found an Abundance of Tokens, which proved too true a Prognostick, that even after so good a Dinner she would by the Evening be in another World. AS to the Eruption of these fatal Characters, I judged them to be rather the Effects of the pestilential corrosive Salt, than of any Putrefaction of the Humours; for this Poison wanting room for Exhalation through the Pores of the Skin, collected in Quantities upon the Surface, and for want of Spirits to strive therewith, imprinted these Marks thereupon. FURTHERMORE these external Parts not only grew dry from the Acrimony of this Venom, but were also very liable to Sphacelation by an Extinction of the vital Spirits; but enough of this, because it would be but adding Light to the Noon-day Sun, to endeavour to confirm it by more Testimonies. THESE _Tokens_ did differ in Regard to their Colour and Hardness; of their Colour we shall speak hereafter: Their Hardness I used to try with a Needle or Penknife, to see whether the Sense and Life was perished or not; in which Trials I found a great deal of Difference, as some would be penetrated with very little Trouble, when others were even callous and horny, and difficult to be penetrated. The Origin of these I conjecture to be from the nervous Juice, or some gelatinous Substance evaporated into a gummy Consistence, not unlike those horny Excrescencies from the Bones; their Colour and Affinity in many Respects with Wharts is also remarkable.
