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.

Barbary Aplin's Cyphering Book contains examples and explanations of arithmetic operations, and genealogical information about the Applin, Sparks, and Coxe families of New Jersey.

The Barbary Aplin Cyphering Book contains examples and explanations of arithmetic operations, and genealogical information about the Applin, Sparks, and Coxe families of New Jersey. The first 10 pages of the book are arithmetic rules, proofs, problems and solutions, and tables. Although the manuscript inscription on the cover is "Barbary Aplin's Cyphering Book," Elizabeth Sparks signed her name on page five, suggesting that she may have contributed to the volume.

Eight additional pages contain sparse genealogical notes regarding the Applin, Sparks, and Coxe families of New Jersey, including birth and death dates for several members of the families. Also of interest is a brief note regarding the deaths of Mary and Hanna Sparks in 1824, accompanied by a small swatch of cloth.

The fourth page of the volume includes a young person's drawings of plants, a person, buildings, a fence, and a bird.

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.

This collection is made up of 2 volumes that Marianna Chandler Lanman composed while studying at Mrs. Rowson's Academy for Young Ladies in Boston, Massachusetts, around 1814. One concerns arithmetic, focusing on practical applications in bookkeeping, conversion, and monetary transactions; the other contains copied poems, calligraphic alphabets, and graphic illustrations.

One concerns arithmetic, focusing on practical applications in bookkeeping, conversion, and monetary transactions; the other contains copied poems, calligraphic alphabets, and graphic illustrations. Lanman dedicated both volumes to her parents.

Lanman composed the first volume, entitled "Practical Arithmetic[:] Comprising All the Rules for Transacting Business" (10"x16", 60 pages), at Mrs. Rawson's Academy in 1814. Its sections, each labeled in calligraphy, concern mathematical operations, rules and theorems; weights and measures; and practical applications of mathematical principles. Many of the later pages concern subjects such as the calculation of simple and compound interest, the value of "federal money" against "lawful money" (state currencies), commission charges, and bookkeeping. The explanatory text is accompanied by finished exercises and problems. The volume also includes tables of weights and measures and an index.

The second volume, "Specimens of Penmanship" (16"x10", 23 pages), is undated. Lanman copied poetry and proverbs on the book's odd-numbered pages; most concern subjects such as happiness, rural living, and gratitude. The title of a poem on the "Pleasures of retired Life" is written on a drawing of a ribbon (p. 19). One poem, entitled "Virtue's Tears Embalm the Brave," is dedicated to the memory of American casualties of the War of 1812 (p. 21). The volume contains several drawings: a hermit in his home (p. 3), a bald eagle among patriotic decorations (p. 21), a sailing ship (p. 21), and a line drawing of a bird with the word "industry" in its feathers (p. 23). The volume also includes examples of cursive, German, and Old English alphabets.

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.
