John Benbow, Jr., of Cowley Hall Mills, Middlesex, England, was an avid amateur beekeeper in the 1840s and 1850s. His "Bee Book" is a small (16mo) copiously illustrated treatise and journal of beekeeping. Divided into three parts -- "Other people's experiments," "Our own experiments," and an annual log (1846-1854) -- the book includes information on hive construction, seasonal management, the cleaning of hives, and other miscellaneous information culled both from printed sources and personal "experiments." The 44 pen and ink drawings include technical drawings of hives and beekeeping apparatus, along with humorous sketches of the activities of an "amateur apiarian."

William Clark kept this diary on an expedition to make a treaty with the Osage Indians in the Missouri Territory. A sketch drawn under the September 16 entry is apparently a draft of Clark's Fort Osage map, while the first page of notes presents color scheme used on another draft. See Kate L. Gregg, Westward with Dragoons (1937: 48) for the map in printed version.

A merchant and member of the Society of Friends, Pim Nevins (1756-1833) lived most of his life in the English midlands. Recorded in Pigot's Directory of 1834 as a member of the gentry resident in Hunslet Lane, Leeds, Nevins was a woollen cloth manufacturer, finisher, and merchant whose operations were located at Larchfield Mill, near Huddersfield. During a voyage to visit Friends' meetings in the United States in 1802-1803, Pim Nevins kept a journal to record his thoughts and experiences. In presenting a copy of his diary to his children, he wrote: "some parts [of the diary] wch. being by way of memorandum to assist my memory will of course be no ways interesting to you; other parts being fill'd with the effusions of my own thoughts, will I fear be dry to you unless your minds should in some measure be dip'd into the like state with mine when influencing my pen; some other parts may entertain you." The journal includes a mixture of description of the cities, towns and landscape through which Nevins passed and accounts of his visits with Friends in New York city, Philadelphia, Wilmington, Baltimore, Washington, Alexandria, Bethlehem, Pa., Easton, Pa., the Pocono Mountains, northern New Jersey, New Brunswick, N.J., and Trenton, N.J. It also includes a delicate watercolor drawing of the Delaware Water Gap.

This diary records the travels of Loammi Baldwin in the Netherlands (then including Belgium), England, and France, with detailed observations and careful pen-and-ink sketches of canals and canal machinery.

A physician, natural historian, and professor at the University of Pennsylvania, Benjamin Smith Barton (1766-1815) was one of the central figures in Philadelphia's early national scientific establishment. Having received his medical training in European universities, Barton was appointed Professor at the University of Pennsylvania in 1789, lecturing on botany, materia medica, natural history. A prolific author, he established his reputation as one of the nation's preeminent botanists through his botanical text book The Elements of Botany (1803), but his contribtions to zoology, ethnology, and medicine were equally noteworthy. Barton's monograph on the "fascinating faculty" of the rattlesnake and his efforts in historical linguistics (New Views of the Origin of the Tribes and Nations of America, 1798) were widely read, and his Philadelphia Medical and Physical Journal (1804-1809) was one of the nation's first medical journals and an important outlet for natural historical research. The Barton Papers offer a comprehensive view of the professional work of Benjamin Smith Barton from the time of his return to the United States in 1789 until his death. The collection is divided into five series: Correspondence, Subject Files, Bound Volumes, Graphic Materials, and Printing Plates. The collection includes a particularly valuable series of botanical, medical, and natural historical drawings collected by Barton for research, reference, and publication. Among the many artists represented are William Bartram, Frederick Pursh, Pierre Turpin, and Benjamin Henry Latrobe.
