The papers of George Royal consist of 24 undated composition books filled with notes by Dr. Royal, professor and dean of the State University of Iowa Homeopathic Medical Department from 1892 to 1921. The first book covers general education courses and appears physically to be from an earlier period than the others, perhaps from his high school studies or while at Amherst College during the early 1870s. Notebooks two and six cite materials published during the early 1890s, which were likely current, and this connects the notes with Royal's early years at SUI.Each of the composition books describes the medical uses of several plants, which are identified by their scientific names in the box list below. These notes are a product of Royal's research on the efficacy of homeopathic remedies, for which he was internationally known.Some of the notebooks were singed, presumably in the 1929 fire which destroyed the Homeopathic Hospital.
