Daniel Conover composed this mathematics exercise book containing definitions, problems, solved examples, rules, cases, and remarks. Subjects covered include practical geometry, mensuration of superficies, conic sections, mensuration of solids, and cylindrical rings. Short sections relate to the application of the principles to the work of artificers, bricklayers, masons, carpenters and joiners, slaters and tilers, plasterers, painters and glaziers, pavers, as well as the construction of roofs and measuring timber. Conover illustrated examples of geometric shapes and angles, some painted with watercolors. A watercolor painting of a building also appears in the volume.

The collection consists of two volumes relating to the Dunwoody family of Marple Township, Pennsylvania, produced between 1807 and 1829. The first volume is a memoranda and expense book kept primarily by James Dunwoody, between 1807 and 1815. It documents financial transactions for meat and livestock, crops, and farm labor. Records also indicate when female laborers began their employment with the family, likely for domestic service, listing the wages and expenses for three of them. The second volume is a copybook kept by Jane B. Dunwoody in 1829 while attending the Marple Union Seminary, focusing on practicing forms for banking, business, legal, and real estate transactions.

The collection consists of two volumes relating to the Dunwoody family of Marple Township, Pennsylvania, produced between 1807 and 1829. The first volume is a memoranda and expense book kept primarily by James Dunwoody, but with references to his sons John, William, and Joseph, between 1807 and 1815. It documents financial transactions for meat and livestock, crops, and farm labor, with several entries with women or notes about cash being provided to wives. Records also indicate when female laborers began their employment with the family, likely for domestic service, including one under-age girl who took up work with her parents' consent and one African American woman ("Black Hariott"). It lists the wages and expenses of Hannah Griffith, Anna Griffith, and Hanah Sithers, documenting the items they were acquiring while in the employ of the family. A recipe for making pills is present, as well as a page of household expenses. The volume has paper covers with woodcut illustrations of four scenes: "Two Sturdy Bull Dogs," "The Fox and the Goat," "An Ass and His Master," and "A Dog and his Shadow."

The second volume is a copybook kept by Jane B. Dunwoody in 1829 while attending the Marple Union Seminary, focusing on banking, business, legal, and real estate transactions. She studied document forms, such as indentures for apprentices, promissory and judgement notes, property leasing, proxy votes, bonds, bills of sale, mortgages, among others. The volume has illustrated, printed covers. The front cover is labelled "The Pet Lamb" and shows a man holding a lamb in his arms with pasted-on letters "JBD Book," and the back cover is labelled "The Pheasant" and shows a pheasant accompanied by a description of the bird by Goldsmith.

The Isam Leonard Arithmetic Book includes mathematical rules, questions, practical examples, and solved exercises covering subtraction, multiplication, division, addition, reduction, fractions, decimals, the single rule of three direct, inverse and compound proportions, and simple interest. The volume includes calligraphic lettering and designs. One undated, unsigned pencil drawing of the "Old Mill at Iffley" is tipped into the volume.

In 1820, Robert Galbreath created this cypher book, sold by Bennet & Walton of Philadelphia, Pennsylvania. It includes rules, examples, and exercises for vulgar fractions, raising of powers, square and cube roots, measurements, gravity, and applied mathematics for walling, masonry, paving, shingling, plastering, and digging. The volume has several pen-and-ink drawings of geometrical objects related to math problems.
