May 28. Yesterday dined here his honor Judge Murray Hoffman, Bidwell, G.F. Allen, Professor Guyot of Princeton,* and Mr. Ruggles. Guyot talks like a man of learning and original thought; rather disposed, perhaps, to strain his analogies too far, to stretch his grand generalizations on the universe till they become mere all-pervading floods of moonshine. Hes our possible post-graduate lecturer on geology, and I dont know that we can do better than take him.
*Arnold Henry Guyot (1807-1884), the Swiss-born geographer, had been invited to America by Agassiz, and in 1854 had accepted the chair of physical geography and geology at Princeton where he is commemorated by Guyot Hall.
