Her presence doubtless coloured all the scenes through which I passed, yet they were enough of themselves to impress my mind. We alighted on the mainland and made our way out towards the archway which spanned the root of the promontory. The weight of our bodies as we stood upon a certain spot swung up the transparent portcullis, and we found ourselves in a spacious entrance hall, its roof a moving orrery of the sky of night, its walls lit pictures of the ocean around framed in living sections of the sea alive with sea-denizens, its floor a tidal beach of sand, soft yet firm, whereon the sea ever seemed to cream and retreat. It had all the beauty and the freshness of the shore beneath the starred night when the tide is making. The next chamber we entered was as vast, and was as many-coloured as the rainbow. It was the index hall; for here were marked the name and number and situation of every chamber in Oomalefa, and underneath each name was shown in graphic experiment the effect of the different medicated atmospheres upon the various tissues of the human body. Complete reproductions of the bones and muscles, the flesh and blood, the cells and nerves and coatings were here enclosed and the transformations pictured in the transparent sections of the walls. An expert from the family having the manufacture of each atmosphere under its charge stood by and guided and explained the process. It was a physiological laboratory, in which every Limanoran might see with his own eyes and hear explained by one who knew, every modification in the tissues that a longer or shorter time spent in any chamber would produce. Twin with this hall was that of measurement and consultation. Here every entrant had all his important organs and tissues tested scientifically, and was then told the atmospheres which would best suit the development of any or all of his parts and faculties. He stated the chief purpose of his existence, and consulted the experts on the directions that would best lead to it. He was told of any defect in his organic functions and advised how it could be remedied. After this consultation he could return to the hall of experiment and see with his own eyes the effect of the various atmospheres upon the unseen portions of his system. Then he was permitted to enter the halls of nutrition and medication, and choosing those which he specially needed that day spent the time required in each. He found exit again by the hall of measurement, and there another testing revealed whether he had been successful in his alimentary sojourn in Oomalefa, and whether he would have to remain longer or have a certain atmosphere introduced into his sleeping-chamber in his own mansion.
