These papers include correspondence from over 180 individuals, lecture notes and essays on mathematics, astronomy, and electricity, and his diaries from journeys through Germany (1798) and Switzerland (1802).

The first fifteen volumes of these "Notes of Travel" are Lea's account of his trips to Europe during 1832 and 1852-1853. He met with naturalists, scientists, and did much sightseeing in England, France, Germany, Italy, and Austria. He records in detail visits and discussions with scientists, and makes sketches of many of the places he saw, particularly the Rhine River. The sixteenth volume is a memorandum book, 1853, containing accounts and expenses while in Europe.

This set of journals, copied legibly but with many excisions into the last volume, 914 Sm61, is from a tour of Germany, Denmark, Sweden, France, and England, to inspect technological improvements in manufacturing and mining. There are accounts of visits with C.D. Ebeling, Friedrich Klopstock, J.A.J. Reimarus, Anders Sparmann, and Karl P. Thunberg. Smith bequeathed this journal to the American Philosophical Society with the request that it be published if found to contain information "useful to the manufactories of my country."

William John Hamilton (1805-1867) English geologist and eldest son of the famed antiquarian and purchaser of the Rosetta Stone, William Richard Hamilton (1777-1859), studied at the University of Goettingen from 1825-1827. The Hamilton Papers consists principally of correspondence written by William John Hamilton to his parents, reflecting the young geologist's intellectual development, his course of study, student life, and holiday travels. Arranged chronologically, the letters mirror the political and cultural events of the period.

There are data on the Japanese, Chinese, Ainu, and French languages, and on Japanese manners and customs, wit and humor, gardening, painting, measurements, swords, etc. Notes and data on the life, travels, and publications of Bernard Varenius. Notes collected for Lyman's Vegetarian Diet and Dishes. Materials on the geology of New Jersey, Ohio, Pennsylvania, Virginia, Iowa, Colorado, New Mexico, and West Virginia; and on coal and iron fields in those states and elsewhere. Manuscripts of articles on instruments for boring wells, theodolites for mining and civil engineers, other surveying instruments, etc. >>> Of particular note is Lyman's period of study in Europe, where he attended the Imperial School of Mines in Paris, France (1859-1861), and the Royal Academy of Mines, Freiberg, Germany (1861-1862). There are about eleven notebooks for this period, written in English, French, and German, that contain: lecture notes, travel observations, comments on geology, mines and mining, railroads, with sketches of machinery, etc. There are a large number of letters (ca. 7,000 items), 1850-1917, from and to Lyman, on personal and business affairs.
