On July 30, 1896, Higginson wrote in his journal: "Sent to printers first (new) instalment of narrative... Collapse... This involves putting back on milk diet and cessation of drives for a time."
This relapse also forced Higginson to give up some of his upcoming lectures and trips (one was planned for England). He was resigned to his condition and, in the same journal entry, speculated: "Very possibly semi-invalidism for the rest of my life. Still this to be quietly faced and recognized." Elsewhere, on the cover of this journal, he wrote: "Now that I begin to know a little, I die."
His concern was unfounded, however. Higginson soon recovered and made his trip to Europe after all. Even so, he noticed the positive aspect in his experience as a "semi-invalid." He had read 42 books during the period, for example, and his focus on writing allowed him to earn more money than ever before. Higginson lived for a couple decades longer before his death in 1911.
