One prophecy, indeed, made on that carnival evening, made in mockery, was fulfilled: Hans Castorp’s fever chart did display a sharply rising curve. He marked it down with a feeling of solemnity. Thereafter it fell a trifle, and then ran on, unchanged save for slight undulations, well above its accustomed level. It was fever, the degree and persistency of which, according to the Hofrat, was out of all proportion to the condition of his lung. “H’m, young fellow me lad, you’re more infected than one would take you for,” he said. “We’ll have to come on to the hypos. They’ll serve your turn, or I’m a Dutchman. In three or four months you ought to be as fit as a fiddle.” Thus it came about that Hans Castorp had to produce himself, twice in the week, Monday and Saturday after the morning exercise, down in the “lab,” where he was given his injections.
