"'I assert my former assertion,' began Kopy-Keck, with a plunge. 'There is not a fault in the princess, body or soul; only they are wrong put together. Listen to me now, Hum-Drum, and I will tell you in brief what I think. Don't speak. Don't answer me. I won't hear you till I have done.--At that decisive moment, when souls seek their appointed habitations, two eager souls met, struck, rebounded, lost their way, and arrived each at the wrong place. The soul of the princess was one of those, and she went far astray. She does not belong by rights to this world at all, but to some other planet, probably Mercury. Her proclivity to her true sphere destroys all the natural influence which this orb would otherwise possess over her corporeal frame. She cares for nothing here. There is no relation between her and this world. "'She must therefore be taught, by the sternest compulsion, to take an interest in the earth as the earth. She must study every department of its history--its animal history; its vegetable history; its mineral history; its social history; its moral history; its political history; its scientific history; its literary history; its musical history; its artistical history; above all, its metaphysical history. She must begin with the Chinese Dynasty, and end with Japan. But first of all she must study Geology, and especially the history of the extinct races of animals--their natures, their habits, their loves, their hates, their revenges. She must----' "'Hold, h-o-o-old!' roared Hum-Drum. 'It is certainly my turn now. My rooted and insubvertible conviction is that the causes of the anomalies evident in the princess's condition are strictly and solely physical. But that is only tantamount to acknowledging that they exist. Hear my opinion.--From some cause or other, of no importance to our inquiry, the motion of her heart has been reversed. That remarkable combination of the suction and the force pump, works the wrong way--I mean in the case of the unfortunate princess: it draws in where it should force out, and forces out where it should draw in. The offices of the auricles and the ventricles are subverted. The blood is sent forth by the veins, and returns by the arteries. Consequently it is running the wrong way through all her corporeal organism--lungs and all. Is it then all mysterious, seeing that such is the case, that on the other particular of gravitation as well, she should differ from normal humanity? My proposal for the cure is this:
