Hans Castorp counted, tested, compared; he studied the structure and grouping of calyx and petals as well as the male and female organs; compared what he found with the sketches and diagrams in his book; and saw with satisfaction that these were accurate when tested by the structure of such plants as were known to him. Then he went on to those he had not known the names of, and by the help of his Linnaeus established their class, group, order, species, family, and genus. As he had time at his disposal, he actually made some progress in botanical systematization on the basis of comparative morphology. Beneath each dried specimen in his herbarium he carefully inscribed in ornamental lettering the Latin name which a humanistic science had gallantly bestowed on it; added its distinguishing characteristics, and submitted the whole to the approval of the good Joachim, who was all admiration.
