Letter from William Prescott to Oliver Prescott, 1782 October 19

Two-page handwritten letter from Harvard undergraduate William Prescott to his classmate, Oliver Prescott, that chiefly describes, in florid language, the discipline received by John Rowe (Harvard AB 1783) and others from College officers for disorderly behavior.

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).
