It may be proper to ask here how long it may be supposed men might have the seeds of the contagion in them before it discovered itself in this fatal manner,and how long they might go about seemingly whole,and yet be contagious to all those that came near them.I believe the most experienced physicians cannot answer this question directly any more than I can;and something an ordinary observer may take notice of,which may pass their observations.The opinion of physicians abroad seems to be that it may lie dormant in the spirits or in the blood-vessels a very considerable time.Why else do they exact a quarantine of those who came into their harbours and ports from suspected places?Forty days is,one would think,too long for nature to struggle with such an enemy as this,and not conquer it or yield to it.But I could not think,by my own observation,that they can be infected so as to be contagious to others above fifteen or sixteen days at furthest;and on that score it was,that when a house was shut up in the city and any one had died of the plague,but nobody appeared to be ill in the family for sixteen or eighteen days after,they were not so strict but that they would connive at their going privately abroad;nor would people be much afraid of them afterward,but rather think they were fortified the better,having not been vulnerable when the enemy was in their own house;but we sometimes found it had lain much longer concealed.
Upon the foot of all these observations I must say that though Providence seemed to direct my conduct to be otherwise,yet it is my opinion,and I must leave it as a prescription,viz.,that the best physic against the plague is to run away from it.I know people encourage themselves by saying God is able to keep us in the midst of danger,and able to overtake us when we think ourselves out of danger;and this kept thousands in the town whose carcases went into the great pits by cartloads,and who,if they had fled from the danger,had,I believe,been safe from the disaster;at least 'tis probable they had been safe.
And were this very fundamental only duly considered by the people on any future occasion of this or the like nature,I am persuaded it would put them upon quite different measures for managing the people from those that they took in 1665,or than any that have been taken abroad that I have heard of.In a word,they would consider of separating the people into smaller bodies,and removing them in time farther from one another -and not let such a contagion as this,which is indeed chiefly dangerous to collected bodies of people,find a million of people in a body together,as was very near the case before,and would certainly be the case if it should ever appear again.
The plague,like a great fire,if a few houses only are contiguous where it happens,can only burn a few houses;or if it begins in a single,or,as we call it,a lone house,can only burn that lone house where it begins.But if it begins in a close-built town or city and gets a head,there its fury increases:it rages over the whole place,and consumes all it can reach.
I could propose many schemes on the foot of which the government of this city,if ever they should be under the apprehensions of such another enemy (God forbid they should),might ease themselves of the greatest part of the dangerous people that belong to them;I mean such as the begging,starving,labouring poor,and among them chiefly those who,in case of a siege,are called the useless mouths;who being then prudently and to their own advantage disposed of,and the wealthy inhabitants disposing of themselves and of their servants and children,the city and its adjacent parts would be so effectually evacuated that there would not be above a tenth part of its people left together for the disease to take hold upon.But suppose them to be a fifth part,and that two hundred and fifty thousand people were left:
and if it did seize upon them,they would,by their living so much at large,be much better prepared to defend themselves against the infection,and be less liable to the effects of it than if the same number of people lived dose together in one smaller city such as Dublin or Amsterdam or the like.
It is true hundreds,yea,thousands of families fled away at this last plague,but then of them,many fled too late,and not only died in their flight,but carried the distemper with them into the countries where they went and infected those whom they went among for safety;which confounded the thing,and made that be a propagation of the distemper which was the best means to prevent it;and this too is an evidence of it,and brings me back to what I only hinted at before,but must speak more fully to here,namely,that men went about apparently well many days after they had the taint of the disease in their vitals,and after their spirits were so seized as that they could never escape it,and that all the while they did so they were dangerous to others;I say,this proves that so it was;for such people infected the very towns they went through,as well as the families they went among;and it was by that means that almost all the great towns in England had the distemper among them,more or less,and always they would tell you such a Londoner or such a Londoner brought it down.
It must not be omitted that when I speak of those people who were really thus dangerous,I suppose them to be utterly ignorant of their own conditions;for if they really knew their circumstances to be such as indeed they were,they must have been a kind of wilful murtherers if they would have gone abroad among healthy people -and it would have verified indeed the suggestion which I mentioned above,and which I thought seemed untrue:viz.,that the infected people were utterly careless as to giving the infection to others,and rather forward to do it than not;and I believe it was partly from this very thing that they raised that suggestion,which I hope was not really true in fact.
