This is a detailed account of Robbins' life growing up on a farm in Northumberland County, Pennsylvania, as well as his educational career as a teacher and administrator, with insights into the educational system of the 1880s and 1920s. There are long accounts of domestic and farm life, including making cider, candles, and soap, butchery, and planting. Also included are accounts of the hard life during the economic upheaval of 1873.

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.

Part I contains a series of definitions of the principles of physics. Part II includes chapters on the visible world, the earth, the senses, light, and meteorology.

Opinions delivered before the Law Academy of Philadelphia by the provost and vice provost. The opinions are signed by Peter S. Du Ponceau as provost.

This is a circa eighteenth-century copybook with problems and illustrations in algebra and geometry. There are sections on extraction of the cube root, geometrical definitions of lines and angles, and first rudiments and preparatory problems in plane geometry.

This volume contains "solutions of the practical problems in [John] Gummere's astronomy."

Charles Morton's "System of Physicks" was among the most important texts in natural philosophy in early America, used to teach science and the scientific method to students at both Harvard and Yale from the late 1680s through the 1720s. This fair copy was probably transcribed at one of those institutions in about 1700, and is a fairly complete accounting of Morton's best known work.

A. Sager's brief notes provide an outline for a course of chemistry lectures, ca.1810. The notes, in Swedish, include sections on electricity and phlogiston.

This volume begins with lecture number 23 (1826 December 13) and ends with number 59 (1827 February 21) of Silliman's lectures at Yale College.

These papers pertain to minerals and mining, publications, his play "The Betrothed," St. John's College in Maryland, and Reconstruction in South Carolina.

This collection consists of a rough and finished draft of Coates' lecture, which was delivered before the Phrenological Society of Philadelphia. In it he included a review of Boston professor John C. Warren's work on the nervous system.

These are copies of the Board of Visitors minutes of the Albemarle Academy (25 March-17 June 1814), and Central College (5 May 1817-1819), both of which were forerunners of the university. There are also minutes of the reconstituted university (29 March 1819-7 April 1826, 10-24 July 1828). Among the members of the Board were Thomas Jefferson, James Monroe, and James Madison. Partly in hand of William C. Rives (?).

With a covering letter from the author to Isaiah Thomas, 1793. The manuscript was published by Thomas at Worcester, 1794.

This volume, written between May 3 and December 2, includes essays on mineralogy, the vegetable kingdom (such as botany and fruitification), and the animal kingdom (such as zoology, ornithology, and generation of animals).

The first volume contains mathematical problems, which appear to be college exercises (1814); the second volume is an essay on the projection of the sphere and spherical trigonometry, including an appendix on astronomy (1812); and the third volume is a lecture on natural philosophy, apparently prepared for delivery [n.d.].

This item is a book of calculations, including problems in the elements of astronomy; the calculations of lunar eclipses at Philadelphia, 1747-1761, and of solar eclipses in 1744 and 1752; and Halley's tables of the sun and moon.

This volume contains calculations of the distances of stars, eclipses, and longitude, made by William Maule, James Cresson, Joseph Jeanes, James James, and Robert Hutchinson, pupils in the Friends Academy, where Roberts was a teacher.
