This volume was kept by a student at West Nottingham Academy and contains problems in algebra.

This volume is chiefly devoted to problems involving fractions, as well as a smaller section on geometrical proportions.

This volume includes definitions and problems on parabola, ellipse, and hyperbola.

These papers include diplomas, testimonials, and letters from Benjamin Rush.

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).

This volume contains two selections: the first are problems in geometry and trigonometry, and the second concerning fortifications and their layout. Note on fly-leaf says this volume was found in the Bastile.

This collection includes correspondence to and from Boskovic; a travel journal in Europe; and a large number of manuscripts on astronomy, hydrography, hydro-mechanics, mathematics, geometry, mechanics, and optics; and a volume of poetry.

This item contains much information about his various posts and about conflicts, personalities, and the politics of science. There are also many references and comments about scientific technology of the day, and of such people as Matthew F. Maury. There are numerous letters to A. D. Bache, James Henry Coffin, Charles Henry Davis, and William H. Willcox.

Principally covering botany and agriculture, this collection includes many manuscripts on trees, shrubs, and plants of different species, copies of botanical essays by others, essays on fruit trees, etc., by Auguste Denis Fougeroux de Bondaroy (1732-89), notes and drafts for the latter's revision of Duhamel's Traité des Arbres et Arbustres. Also miscellaneous essays, sketches, and memoranda on bones of birds and animals, electricity, fish, steam engines, ventilation, temperature and air pressure, mathmatics, paleontology ("Observations sur les os d'éléphants fossiles"), chemistry, metallurgy, entomology, architecture, taxidermy ("Méthode pour empailler les oiseaux"); lists of plants; notes on England, Canada, Mexico, China; notes of reading in Pliny, John Evelyn, Alexander Russell, William Derham, and others. An unpublished translation of Jethro Tull's Horse-Hoeing Husbandry, with additions and revisions by Duhamel du Monceau. An alphabetical catalogue of Duhamel's gardens, prepared by Fougeroux de Bondaroy. The collection has manuscript material in pre-publication form along with published material with marginalia for improvements of later editions. There are a multitude of sketches, botanical materials and seed packets. The collection includes lists of American trees and seeds shared with European scientists. Benjamin Franklin acts as a go between French and American botanists and John Bartram sends seeds to France from his garden. Also correspondence (ca. 170 pieces) with, among others, Peter Collinson, Duc d'Aven, Duc de Noailles, Louis J. M. Daubenton, Mathurin Jacques Brisson, Jean François Gauthier, Comte de La Galissonière, Chrétien Guillaume de Lamoignon de Malesherbes, Emerich Vattel. The collection has been described in part by Gilbert Chinard, "Recently Acquired Botanical Documents," APS Proc. 101 (1957): 508: and by Joseph Ewan, "Fougeroux de Bondaroy (1732-1789) and his Projected Revision of Duhamel du Monceau's Traité (1755) on Trees and Shrubs. I. An Analytical Guide to Persons, Gardens, and Works mentioned in the Manuscripts," APS Proc. 103 (1959): 807.

Robert Maskell Patterson (1787-1854, APS 1809) was a professor of chemistry and natural philosophy at the University of Pennsylvania (1812-1828) and professor of natural philosophy at the University of Virginia (1828-1835). He was director of the U.S. Mint from 1835 to 1851. His father, Robert Patterson, was a revolutionary soldier, professor of mathematics at the University of Pennsylvania (1779-1814), and director of the U.S. Mint (1805-1824).
