Exhalations, either breathed in at the Mouth or Nofe, and fo affeft- 
ing the Lungs and Brain, or piercing ;thrOPgh the Skin into the o- 
ther parts of the Body, and there working , not by CeagnUtion (as 
Dr. ^i//// would have it, on whom the Author animadverts, though 
very civilly,) but by Corr^/fi^;;, which, in his opinion , depends not 
from Heat or any other of the four Firft Qualities, celebrated in the 
Schools, but from a certain Conformation of Salin corrofive par- 
ticleSjmanLfcftin y^r/mV^, by many effcds, here fpecified, and par- 
ticularly thofe, that have been obferved in the Bodies of fuch as dyed 
of the Plague, in which not only the interior membrane of the Sto- 
mach, but alfo all the Bowels have been found corroded , black, 
fphacelated and corrupted. Yethedenieth not, but that with this 
Arfenicd venom fome Other, and tfptchUy Mercfiriai, Vapors may 
concur, which being joyned and fublimed together with other Vo- 
latil particles become highly deflruSive, being taken into fuch Bo- 
dies, as were predifpofed, before others, to receive them by their 
depraved conftitution, or by a ^too great fulnefs of bloud, orob- 
flrudions, or perturbations of humors caufed from fancy , fear and 
confternation, &c. 
As for the Spreadingnefs of the Plague, he efteems, and endea- 
vors to evince, that it is not fo Contagious as is commonly believed; 
but that , (Whereas there are ten perhaps that get it by infedion 
from others , there are thoufands that are ftruck with it from, 
the Air , harbouring the feeds of it in a peftilentiai conlHtu- 
tion. 
In the o//?rr Differ tation the Author delivers the fcveral Means of 
Curing the Plague ^ either by expelHng, or difperfing, or intang- 
ling, or rebating, or fixing, or impeding the penetration of thofe 
Corrofive particles, that invade the Body where he mentions the 
fevcral remedies, by him judged proper in the faid refpeftive me- 
thods : Concluding with a difcourfe about the beft wayes of Prefcr- 
vation from the Plague V of which he prefcribeth principally thcfe 
three, either by Retiring a far off, or by Correding, or by Forti- 
fying our felves againft the Peflilential Air ^ adding his thoughts^ 
how the two lattex wayes may he beft performed.
