This arithmetic copybook was compiled by an anonymous student in the nineteenth century. It includes rules and examples for addition, subtraction, multiplication, and division, as well as practical examples relating to money and weights and measures.

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.

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.

This currently unidentified student's cypher book contains mathematical rules and examples largely in the service of commerce. Entries relate to the addition of money, addition of Troy weight, addition of dry measure, subtraction, a numeration table, a multiplication table, the Golden Rule (i.e. the rule of three), and similar concepts. Currency in this volume is almost exclusively British coinage, but at least one problem references conversion of British pounds into the (newly created) U.S. dollar. The covers of the volume are (apparently re-used) canvas, possibly sailcloth. The cypher book was owned by the Higgins family of Cape Cod, Massachusetts, and it contains names of Higgins family members, but the author is yet undetermined.

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.

This cypher book, by Theophilus Norris of Epping, New Hampshire, contains mathematical rules, examples, and exercises. Entries also relate to practical uses, including surveying, weights and measures, and compound interest. Several handwriting exercises are also present, as well as brief genealogical notes relating to Elizabeth Brier and Elizabeth Norris.

The William Yardley Mathematics and Surveying Exercise Book contains solved geometric, trigonometric, and surveying exercises, including practical problems and illustrated examples that feature drawings of buildings, animals, and landscape elements.

One letter written by Harry [Crockett?] to his mother, Mrs. L. F. Crockett, from Portland, Maine, on October 8, 1903, is laid into the volume. Written on John W. Perkins Company, Wholesale Druggists, illustrated stationery, the letter comments on family matters, business, and deaths of acquaintances, including one gentleman who was killed by an electric car.
