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

These contain a few notes and memoranda by Van Vleck, but the bulk of the collection is letters to and from him. Correspondents include Raymond T. Birge, Gerhard H. Dieke, Paul A. M. Dirac, Edwin C. Kemble, and Robert S. Mulliken.

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 (?).

These volumes contain notes from lectures taken by Wistar and lectures given by Wistar. Subjects include bones, teeth, amputation, and midwifery.

These cards of admission were to lectures held at the University of Pennsylvania, St. George's Hospital (London), and the University of Edinburgh. Rush has written comments on the lecturers on the backs of several of the cards.

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.

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 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.

Notes kept by the Yale undergraduate John Austin Stevens on 20 lectures on natural philosophy delivered by Jeremiah Day during the fall, 1812. Includes lectures on gravitation, mechanics, and hydrostatics (hydrology), the last including theories of rivers, springs, and groundwater.
