June 10 Saturday – Isabel Lyon’s journal: Mr. Clemens has introduced a delightful character into the microbe book—“Katherine of Arragon”—She is so sweet and so foolish and so innocent, and so profane and so sympathetic that she’s exactly right. Mr. Clemens is enjoying the writing of the book so much too. He doesn’t know that Katherine is anywhere around when in she pipes with a remark that staggers that dear cholera germ. Oh, it is so interesting, and its positively holy to hear Mr. Clemens read it [MTP TS 64-65].
