“To judge from the size of the place, this Palace of Green Porcelain had a great deal more in it than a Gallery of Palaeontology; possibly historical galleries; it might be, even a library! To me, at least in my present circumstances, these would be vastly more interesting than this spectacle of oldtime geology in decay. Exploring, I found another short gallery running transversely to the first. This appeared to be devoted to minerals, and the sight of a block of sulphur set my mind running on gunpowder. But I could find no saltpeter; indeed, no nitrates of any kind. Doubtless they had deliquesced ages ago. Yet the sulphur hung in my mind, and set up a train of thinking. As for the rest of the contents of that gallery, though on the whole they were the best preserved of all I saw, I had little interest. I am no specialist in mineralogy, and I went on down a very ruinous aisle running parallel to the first hall I had entered. Apparently this section had been devoted to natural history, but everything had long since passed out of recognition. A few shrivelled and blackened vestiges of what had once been stuffed animals, desiccated mummies in jars that had once held spirit, a brown dust of departed plants: that was all!
