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.

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.

This volume, written by an unknown author, describes general principles of physics, with numerous sketches illustrating the text. There are a few notations in Spanish by Juan Bastolleros.

During the late eighteenth and early nineteenth centuries, the American Philosophical Society regularly received letters, and occasionally full blown manuscripts, from members of the public regarding their ideas on science or technology. In 1829, Edward Mulhern of Philadelphia submitted a manuscript on terrestrial magnetism that he felt had implications for navigation. Little is known about Mulhern other than that he died before 1833. Mulhern's "Dissertation on the doctrine and principles of magnetism &" is an attempt to work through some fundamental issues in terrestrial magnetism, including the relative orientation and positions of the geographic and magnetic poles, with an eye toward their impact on navigation. The APS Minutes for April 15, 1833, read: "An application from Alex Mulhern to have returned to him a paper on the 'doctrine of Magnetism' laid before the society by his deceased father, was received and the Librarian was directed to return the same.'"

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.

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 (?).

This is Taylor's dissertation for the degree of Doctor of Medicine from the University of Edinburgh. It was originally published in Latin (Edinburgh, 1800), and John Brandreth made this English translation for a friend in 1830.

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

Twice a refugee from the revolutionary violence in the French colony of Saint Domingue, John Thomas Carré became head of the Clermont Seminary in Philadelphia from 1804-1825, a select boarding school for boys. Carré's diary from 1807-1809 provides a basic chronology of his life at the Clermont Seminary, with a few comments on his students and their families. The entries are typically very brief and are confined to a relatively limited range of topics, including the weather, Carré's poor health, his visitors, and correspondents. There is also a biographical memoir by his granddaughter, Ann Virginia Sanderson Farquhar.

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