5360. It was observed, that, in one city, almost a fourth part of those who appeared there - who were of a different genius from, and, consequently, turned their back to, the others - only appeared when they turned themselves into some similarity of affection. The portion that was of a wholly different genius, and did not accord with the citizens, were allotted quarters under the city, and this in various places. I beheld, in the London there, the ground heaped up in the shape of a small hill, and an entrance under it. Under the hill there, although it was small, there was an immense number of the wicked, amounting to many thousands, all of whom were then cast into the hells - because from them, as long as they are there, an exhalation arises to the inhabitants of the city, which infests them and changes their affections and thoughts. On some occasions, also, certain ones go out from thence, and make their appearance; but they return again. This occurs under the cities, in many places. Thus, also, are the cities always cleansed by the Lord.
