Oh! my dear, dear neighbour, surely I can't be wrong, surely I'm not making a mistake here: you and I spent many happy days together in Ceylon, just as nearly as possible two hundred years ago? Did we not?" "'Then he got into all sorts of labyrinths of incoherence, and I saw well enough whom I had to do with, and got away from him as quickly as I could, though not without some difficulty. "'When I asked the landlady about him, I found that my neighbour, who had long been a much esteemed savant and man of business, with much many-sided cultivation, had a short time before fallen into a profound _maliconia_, in which he believed that everybody was inimically disposed to him and wanted to do him some harm; till all at once he thought he had discovered the means of finding out those who were his enemies and were hostile to him; upon which he had passed into his present tranquil and contented condition of madness with "fixed idea." It seems he sits nearly all day at his window making experiments with his glass. His own kindly disposition is seen in the circumstance that he nearly always augurs well of the people whom he experiments upon, and when he comes across anybody whom he thinks inimical, or dubious, he is not angry, but droops into a state of quiet sadness. So that his madness is quite harmless, and his elder brother, who manages his affairs, can let him live wherever he chooses, and has no occasion to give himself any trouble about him.' "'So that your ghost,' said Severin, 'belongs to the category of those in Wagner's "Book of Apparitions," inasmuch as your explanation--to the effect that it was due to natural causes, and was chiefly the result of your own imagination--comes dragging in at the tail of the story, as is always the case in that most prosy of books.' "'If nothing short of a ghost will satisfy you,' said Marzell, 'of course that is so. However, this madman of mine with whom I'm now on the most intimate terms--is a very interesting specimen; and there's only one thing connected with him that I don't altogether like, namely, that he's beginning to take to _other_ fixed ideas; for instance, that he's the King of Amboyna, and has been taken prisoner, and exhibited for money about the country, as a bird of paradise, for fifty years. Now that sort of thing is capable of turning into a violent form of insanity. I knew a man who used to shine as the moon in the quietest and happiest madness every night, till he took it in his head that he had got to rise as the sun also, and then he broke out into the wildest violence.' "'My dear fellows,' cried Alexander, 'is this talk for a place like this, in the middle of thousands of people in their holiday clothes, enjoying themselves in the bright sunshine? All we want to make us perfect is that Severin--who's looking much paler and more pensive than I like to see him shall have had some more terrible experience than even we have, and will tell us about it.'
