QUOTE : But when the physicians assured us that the danger was as well from the sound (that is, the seemingly sound) as the sick, and that those people who thought themselves entirely free were oftentimes the most fatal, and that it came to be generally understood that people were sensible of it, and of the reason of it; then, I say, they began to be jealous of everybody, and a vast number of people locked themselves up, so as not to come abroad into any company at all, nor suffer any that had been abroad in promiscuous company to come into their houses, or near them—at least not so near them as to be within the reach of their breath or of any smell from them; and when they were obliged to converse at a distance with strangers, they would always have preservatives in their mouths and about their clothes to repel and keep off the infection. It must be acknowledged that when people began to use these cautions they were less exposed to danger, and the infection did not break into such houses so furiously as it did into others before; and thousands of families were preserved (speaking with due reserve to the direction of Divine Providence) by that means.
