Naborhood in Aqualungs
This one seems to be a cut-up or fold-in of the previous section - So Pack Your Ermines - and some other stuff. The main thing I got from the two of them was the constant mentions of metals, gases, liquids, colours and minerals. He keeps talking about suffocating people, carbon dioxide, silver, aqualungs, diving suits, ice, sapphires, emeralds, people turning blue, acid.
Limestone John luring people into the amphitheatre in order to suffocate them and paint the scene is an odd one. I had to read it a couple of times as I thought he was spraying the people and the painting was him literally suffocating them with paint rather than filling the place with carbon dioxide and painting the scene on the wall.
