Seeing, then, that we could come at the certainty of things by no method but that of inquiry of the neighbors or of the family (and on that we could not justly depend), it was not possible but that the uncertainty of this matter would remain as above.
It is true, masters of families were bound by the order to give notice to the examiner of the place wherein he lived, within two hours after he should discover it, of any person being sick in his house, that is to say, having signs of the infection; but they found so many ways to evade this, and excuse their negligence, that they seldom gave that notice till they had taken measures to have every one escape out of the house who had a mind to escape, whether they were sick or sound. And while this was so, it was easy to see that the shutting up of houses was no way to be depended upon as a sufficient method for putting a stop to the infection, because, as I have said elsewhere, many of those that so went out of those infected houses had the plague really upon them, though they might really think themselves sound; and some of these were the people that walked the streets till they fell down dead: not that they were suddenly struck with the distemper, as with a bullet that killed with the stroke, but that they really had the infection in their blood long before, only that, as it preyed secretly on their vitals, it appeared not till it seized the heart with a mortal power, and the patient died in a moment, as with a sudden fainting or an apoplectic fit.
I know that some, even of our physicians, thought for a time that those people that so died in the streets were seized but that moment they fell, as if they had been touched by a stroke from heaven, as men are killed by a flash of lightning; but they found reason to alter their opinion afterward, for, upon examining the bodies of such after they were dead, they always either had tokens upon them, or other evident proofs of the distemper having been longer upon them than they had otherwise expected.
This often was the reason that, as I have said, we that were examiners were not able to come at the knowledge of the infection being entered into a house till it was too late to shut it up, and sometimes not till the people that were left were all dead. In Petticoat Lane two houses together were infected, and several people sick; but the distemper was so well concealed, the examiner, who was my neighbor, got no knowledge
