The volumes were heavy, unhandy. Hans Castorp propped them against his chest or stomach as he lay; they were heavy, but he did not mind. Lying there, his mouth half open, he let his eye glide down the learned page, upon which fell the light from his red-shaded lamp, though he might have read, if need were, by the brilliance of the moonlight alone. He read, following the lines down the page with his head, until at the bottom his chin lay sunk upon his breast⁠—and in this position the reader would pause perhaps for reflection, dozing a little or musing in half-slumber, before lifting his eyes to the next page. He probed profoundly. While the moon took its appointed way above the crystalline splendours of the mountain valley, he read of organized matter, of the properties of protoplasm, that sensitive substance maintaining itself in extraordinary fluctuation between building up and breaking down; of form developing out of rudimentary, but always present, primordia; read with compelling interest of life, and its sacred, impure mysteries.
