CHAP. IX. Of GANGREN'S.
GAngren's are of the Nature of the Plague; and they are of Two sorts, as the Plague is; the one more sudden and deadly than the other: The only difference of their Insecting Qualities, is, That Gan∣gren's spread by insecting still the next, or Neigh∣bouring Parts; whereas Plagues infect Forrein, as much as Home-Parts. Also, the deadly sort of Gan∣gren's, infect (as I may say) from the Circumference towards the Center: when as the deadly sorts of Plague, infect from the Center, towards the Circum∣ference. But, that sort of Gangrene that is the weaker sort, infects only the next adjoining Parts, by degrees, and after a spreading manner, rather than after a pier∣cing manner.
But some may object, That Plagues and Gangren's are produced from different Causes; as for example, Extream Cold will cause Gangren's; and Extream Heat causes Plagues.
I answer, That Two opposite Causes may pro∣duce like Effects, for which may be brought numerous Examples.
