Treatise on mathematics and astronomy: written about the year 1680, in Boston

Bound volume containing a late 17th century handwritten mathematical and astronomical text in one hand. The text is separated into mathematical and astronomical sections with rules, instructions for performing calculations, tables, and drawings. The subjects include arithmetic, geometry, astronomy, and trigonometry, and segments have titles such as "Subtraction," "A decimal table of English coince," "Logarithes & their use," and "To find the true place of the sun." The text is undated and unattributed but references Briggs, Oughtred, Ramus, and Apollonius. Certain tables are calculated from latitudinal and longitudinal numbers associated with Boston, and many of the examples use dates in the 1670s and 1680. The manuscript pages are mounted onto unruled pages, and some of the manuscript pages are fragments.

Deeds for properties in Boston [and Cambridge?], 1798-approximately 1945 (inclusive); approximately 1880-1920 (bulk)

This group of records contains deeds and related documents for a selection of properties owned by Harvard University in Boston and possibly Cambridge and other nearby communities through the mid 1940s. Documents include deeds, assignments of mortgages, receipts, correspondence, and other legal documents. Many of the documents record property transfers prior to Harvard's acquisition of the property, and often the documents do not fully identify Harvard's involvement with the property. The bulk of the documents date from the late 19th and early 20th centuries.
