“Clear picture,” said the Hofrat, “quite a decent leanness⁠—that’s the military youth. I’ve had paunches here⁠—you couldn’t see through them, hardly recognize a thing. The rays are yet to be discovered that will go through such layers of fat. This is nice clean work. Do you see the diaphragm?” he asked, and indicated with his finger the dark arch in the window, that rose and fell. “Do you see the bulges here on the left side, the little protuberances? That was the inflammation of the pleura he had when he was fifteen years old. Breathe deep,” he commanded. “Deeper! Deep, I tell you!” And Joachim’s diaphragm rose quivering, as high as it could; the upper parts of the lungs could be seen to clear up, but the Hofrat was not satisfied. “Not good enough,” he said. “Can you see the hilus glands? Can you see the adhesions? Look at the cavities here, that is where the toxins come from that fuddle him.” But Hans Castorp’s attention was taken up by something like a bag, a strange, animal shape, darkly visible behind the middle column, or more on the right side of it⁠—the spectator’s right. It expanded and contracted regularly, a little after the fashion of a swimming jellyfish.
