A plan of Cambridge Green, 1780 September 14

Small pen-and-ink and watercolor drawing of Cambridge Green created by Harvard senior John Davis, presumably as part of his undergraduate mathematical coursework. The map surveys Cambridge Commons and includes a few rough outlines of College buildings and the Episcopal church, and notes the burying ground, and the roads to Charlestown, Menotomy, the pond, Watertown, and the bridge. The original handwritten text is faded and was annotated with additional text by Davis including the note "[taken in my Senior year at H. College Septr 1780] Surveyed in concert with classmates, Atkins, Hall 1st, Howard, Payne, &c.- J. Davis." There is a note that "Atkins afterwards took the name of Tying." Davis refers to Dudley Atkins Tyng, Joseph Hall, Bezaleel Howard, and Elijah Paine, all members of the Harvard Class of 1781.

Notebook of Obadiah Ayer, 1708-1716

The leather-bound notebook contains academic texts copied by Obadiah Ayer while he was a student at Harvard, and after his graduation in 1710. There is a general index to the included texts at the end of the volume.

Student notebook of Samuel Dunbar, 1721-1722

This leather-bound volume contains substantial transcriptions copied by Samuel Dunbar from textbooks while he was a student at Harvard in 1721 and 1722. There is a general index to texts at the end of the volume. Dunbar's notebook provides a window into the state of higher education in the eighteenth century and offers a firsthand account of academic life at Harvard College. Notably, he often indicated the number of days spent copying texts into his book.

Student mathematical textbook of James Freeman, 1774

Manuscript volume containing portions of text copied from Nicholas Saunderson’s Elements of algebra, Nicholas Hammond’s The elements of algebra, and John Ward’s The young mathematician’s guide. The volume is divided into two main parts: the first is titled Concerning the parts of Arithmetick (p. 1-98) and the second, The elements of Algebra, extracted from Hammond, Ward & Saunderson (p. 99-259).

Student mathematical notebook of Thomas Noyes, 1793

This sewn volume contains Noyes’ mathematical exercises in geometry; trigonometry; surveying; measurement of heights and distances; plain, oblique, parallel, middle latitude, and mercator sailing; and dialing. Many of the exercises are illustrated by carefully hand-drawn diagrams, including a mariners’ compass and moon dials.

Student mathematical notebook of Ebenezer Hill, 1785

This mathematical notebook of Ebenezer Hill was kept in 1795 while he was a student at Harvard College. The volume contains rules, definitions, problems, drawings, and tables on arithmetic, geometry, trigonometry, surveying, calculating distances, and dialing. Some of the exercises are illustrated by hand-drawn diagrams, including some of buildings and trees.

Student mathematical notebook of Ephraim Eliot, 1779

Handwritten mathematical notebook of Ephraim Eliot, kept in 1779 while he was a student at Harvard College. The volume contains rules, definitions, problems, drawings, and tables on arithmetic, geometry, trigonometry, surveying, calculating distances, and dialing. Some of the exercises are illustrated by unrefined hand-drawn diagrams, as well as a sketch of a mariner’s compass. The sections on navigation, mensuration of heights, and spherical geometry are titled but not completed. The ink of the later text, beginning with Trigonometry, is faded.

Commonplace book of Benjamin Penhallow, 1721-1724

This leather-bound volume contains excerpts copied by Benjamin Penhallow from books he read while he was a student at Harvard in the 1720s. The volume contains extracts from two texts: Johanis Henrici Alstedii's (John Henry Alsted / Johann Heinrich Alsted) Geometria Domini, and the anonymous text "The Legacy of a dying Father; bequeath'd to his Beloved Children, or Sundry Directions in Order unto a well Regulated Conversation," from 1724 (originally published in 1693-4). The last page of text in the volume contains the hymn "The Sacred Content of Praise" first published in 1734, and added after Penhallow's death.

Student notebook of James Varney, 1721-1725

The bound notebook contains academic texts copied by Harvard student James Varney in the early 1720s. The texts are written tête-bêche (where both ends of the volume are used to begin writing). The front paste-down endpaper reads 'James Varney his book 1724,' and the rear paste-down endpaper reads 'Joseph Lovett' [AB 1728].

Student mathematical notebook of William Emerson Faulkner, 1795

Leather hardcover notebook with unruled pages containing the handwritten mathematical exercises of William Emerson Faulkner, begun in 1795 while he was an undergraduate at Harvard College. The volume contains rules, definitions, problems, drawings, and tables on geometry, trigonometry, surveying, calculating distances, sailing, and dialing. Some of the exercises are illustrated by unrefined hand-drawn diagrams, including some of buildings and trees.

Student mathematical notebook of William Tudor, 1795

Notebook containing the handwritten mathematical exercises of William Tudor, kept in 1795 while he was an undergraduate at Harvard College. The volume contains rules, definitions, problems, drawings, and tables on geometry, trigonometry, surveying, calculating distances, sailing, and dialing. Some of the exercises are illustrated with hand-drawn diagrams. The Menusration of Heights and Distances section contains color drawings of buildings and trees, and some have been altered with notes in different hands and with humorous additions. For instance, a drawing of a tower was drawn into a figure titled “Egyptian Mummy.” Some of the images are identified: “A rude sketch of the Middlesex canal,” Genl Warren’s monument on Bunker Hill,” “Noddles Island,” “the fields of Elysium,” and the “Roxbury Canal.” The annotations and additional drawings are unattributed.

Mathematical notebook attributed to Thaddeus Mason Harris, ca. 1787

Hardcover notebook containing handwritten transcriptions of rules, cases, and examples from 18th century mathematical texts. The author and purpose of the volume is unclear, though it has been connected with Thaddeus Mason Harris (Harvard AB 1787). Most of the entries include questions and related answers, suggesting the notebook was used as a manuscript textbook and workbook. The extracts appear to be copied from John Dean's " Practical arithmetic" (published in 1756 and 1761), Daniel Fenning's "The young algebraist's companion" (published in multiple editions beginning in 1750), and Martin Clare's "Youth's introduction to trade and business" (extracts first included in 1748 edition).

Student notebook of Marston Cabot, ca. 1720-1735

This leather-bound volume contains excerpts copied by Marston Cabot from books he read while he was a student at Harvard in 1723. The volume includes extracts from Charles Morton's 1687 Compendium Physicae (titled "of Phisicks" by Cabot), Dr. Adriani Heereboord (Adrianus Heereboord), Philosophia Naturalis and Johanne-Henrico Alstedio’s (John Henry Alsted) geometry text Compendium Geometria. The excerpts from Compendium Geometria include both figures and text, primarily in Latin with some Greek. The volume also includes “Theses quaedam extractae potissimum ex Enchiridio Metaphysico Domini Johannis Clerici" a précis of Jean Le Clerc's Ontologia et Pneumatologia made by Jonathan Remington, a Harvard Tutor from 1703 to 1711, to serve in place of printed textbooks. The names Jonathan Jackson and Edward Jackson are written on the inside cover, suggesting the book may have been handed down to Edward Jackson (Class of 1726) and his son Jonathan Jackson (Class of 1761). The text of the volume is in Marston Cabot's hand.

Notebook concerning mathematical equations : manuscript, 1769-1774

Notes on measuring height and distance, trigonometry, spherical projection, and other mathematical equations. Probably William Winthrop (1753-1825; Harvard AB 1770).

Of the invention of theorems : manuscript, [17--]

Mathematical notes, equations, theorems, and definitions. Probablynot by William Winthrop (Harvard AB 1770) as it is different handwriting and language habits from other of his manuscript.
