Includes Frammenti de Diario, a fragment of a diary kept on a trip to Britain, circa 1783-1784; Viaggio da Milano a Parigi, journal of a voyage from Milan to Paris, 1784; Viaggi di un gentiluomo milanese, Giornale, typed transcriptions of the travels of a gentleman from Milan, containing notes on the Iroquois Indians, 1790; Giornale de Filadelfia a Quebec, journal from Philadelphia to Quebec, 1791; and, journal of a trip through New York state (including visits to Albany, the reservations of the Six Nations, Saratoga, and the Shaker community at New Lebanon), 1790;

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."

[The following comprises the original Abstract, which will be significantly revised.] >>> These are notes, sketches, memoranda, etc., made while Lyman directed the geological survey of Japan, 1873-1879, with reports on petroleum resources, copper, coal, iron, and gold mines, oil, mineral springs, and other mineral resources of the Japanese archipelago. 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.

The natural historian Richard Harlan was a pioneer in the study of comparative anatomy and vertebrate paleontology in the United States during the years following the War of 1812. Having received his medical degree from the University of Pennsylvania in 1818, Harlan was employed as an instructor of anatomy at Joseph Parrish's school and at the Philadelphia Museum. A practicing physician and member of the Academy of Natural Sciences of Philadelphia and the American Philosophical Society, Harlan made important contributions in comparative neuroanatomy, paleontology, herpetology, and systematic zoology. He died shortly after moving to New Orleans in 1839. Harlan's journals document two of the three overseas voyages he undertook during his lifetime. The first took place in 1816-1817 when Harlan was still a medical student, accompanying an East Indiaman to Calcutta as ship's surgeon. The second took place when Harlan was at the peak of his career in 1833, venturing to England, France, and Italy to strengthen contacts with European colleagues. Interesting travel narratives in themselves, the journals mingle enthusiasm for the new and exotic with a touch of Harlan's truculance. The European journal includes a valuable account of the 3nd meeting of the British Association for the Advancement of Science at Cambridge at which Harlan delivered a paper on fossil reptiles.

After a brief career in the Congregational church, J. Peter Lesley (1819-1903) left the ministry in 1852 to work full-time as a geologist. Having gained experience in structural geology and stratigraphy with the First Pennsylvania Geological Survey (1836-1842), Lesley became an expert in the geology of coal, working for the Pennsylvania Railroad and other corporations and conducting some of the first systematic studies of the state's hydrocarbon resources. A long-time professor at the University of Pennsylvania, he was elected to the APS in 1856, serving variously as its librarian, secretary, and vice president, and he was selected as Director of the Second Pennsylvania Geological Survey (1875-1889). The Lesley Papers include letters to and from Peter Lesley and his wife, Susan on geology, coal and iron mining, abolition, educational reform, organized charity, and Unitarianism. The collection offers important insight into academic and applied geology in late 19th century Pennsylvania, the development of the coal and iron industries, as well as into the Lesleys' progressive social and intellectual milieu. It is divided into three series: Lesley's general correspondence, his correspondence with his brother Joseph, and microfilms of Lesley's research notes.
