The Practical Mathematics manuscript contains definitions and problems related to algebra, geometry, trigonometry, navigation, and surveying. These categories are divided into specific applications; the section on algebra deals with topics such as basic algebraic statements, algebraic fractions, simple and quadratic equations, and arithmetical and geometrical progressions. Most of the problems are accompanied by illustrated figures and/or examples of concepts' practical applications. A section concerning globes pertains to both terrestrial and celestial globes, and includes a list of the signs of the zodiac, as well as descriptions of navigational methods, accompanied by a compass rose and charts, including "Mercator's Charts."

The manuscript also explains methods for determining location and time by observing celestial objects, and contains instructions for keeping ships' logs and surveying notes. A section on navigation includes a copied log from the voyage of the Pegasus from England to Barbados (January 31, 1737-March 22, 1737), as well as a map showing the coasts of France and Spain and the islands around Barbados. Some of the surveying problems are illustrated with a sailing ship, a tree, and a turret.

This log book contains daily reports for a French ship that sailed between the Caribbean and Europe, and around the Mediterranean in the 1730s. The book is preceded by the following statement: "Au nom de dieu soit fait a journal teneu par le St. francois pied noir..."

The bulk of the volume, around 400 pages, consists of daily log entries for voyages between April 1731 and January 1737, written by St. François, "pied noir" [black foot]. Most entries include reports on the weather, winds, and the ship's position. The ship called at Cadiz, Marseille, and St. Malo, among other ports.

The final pages are comprised of additional notes and instructions, such as a list of items sold in Cadiz, an illustrated method for calculating a building's height, and instructions for melting metal and producing gunpowder. An ink drawing of a flower appears on an early page. The volume contains the bookplate of Robert R. Dearden.

The Thomas and Daniel Osborn family papers contain correspondence and documents related to the ancestors and descendants of Yale graduate Daniel Osborn of Cutchogue, New York. The items primarily concern his son Thomas Osborn, a doctor in Riverhead, New York, and his grandson Thomas Gilbert Osborn, a Methodist Episcopal minister in New York and Connecticut. The materials pertain to family relationships and news, religion, property, family history, and other subjects.

The Thomas and Daniel Osborn family papers (81 items) contain correspondence and documents related to the ancestors and descendants of Yale graduate Daniel Osborn of Cutchogue, New York. The materials pertain to family relationships and news, religion, property, and family history, among other subjects.

The bulk of the collection is comprised of correspondence to and between members of the Osborn family, particularly Dr. Thomas Osborn of Riverhead, New York, and his son, minister Thomas Gilbert Osborn of Suffolk County, New York; Connecticut; and New York City. Dr. Thomas Osborn provided his son with family news from Riverhead, New York. Thomas Gilbert Osborn wrote about his experiences at a seminary in New York in 1841 and travel to the Azores on board a whaling vessel in the fall of 1842. Thomas G. Osborn later told his wife Jerusha of his father's failing health and funeral in the summer of 1849. Their letters also refer to finances, local news, and other aspects of everyday life. Thomas G. Osborn's incoming letters from acquaintances frequently pertain to the writers' religious beliefs.

The nine Tomas Gilbert Osborn diaries cover selected months between November 1, 1841, and April 6, 1844. At the time, he lived in Riverhead, New York, and his writings pertain to his educational and social life, employment, and health. He documented his efforts towards entering the law profession, including working with a lawyer in Riverhead, attending a semester at Harvard Law School, and reading legal texts. Othe educational and personal improvement efforts include notes on books read, reflections on historical and prominent figures, religious commentary, resolutions towards upright living, and involvement with the temperance movement.

Thomas G. Osborn's medical ailments are also featured heavily, primarily his ongoing bowel complaints and efforts to adjust his diet and lifestyle to recover his health. Medical notes, excerpts of medical texts, different advice and diets are covered in relation to dyspepsia and chronic diarrhea. In an effort to bolster his health, Osborn went on a mackerel fishing expedition, which he documents in detail, and joined a whaling voyage against his parents' wishes (see esp. entries beginning September 19, 1842). Capt. Rose [Jetur Rose?] was master of the vessel, apparently called Caroline. His entries about the expedition and his role as steward provide insight into labor, personal relations, illnesses, and diet onboard. A subsequent diary relates his and several crewmates' stay at a hospital at Faial, Azores, as they recovered from dysentery and other ailments, as well as an unpleasant sea voyage back to America. Several entries relate to the African American book during that homeward voyage, and sporadic mentions of African Americans can be found throughout the volume. Upon his return home, Osborn's journals turn more to documenting social visits, religious matters, and his entrance into preaching.

The collection includes several documents and ephemeral items. Three indentures concern Daniel Osborn's acquisition of land from 1737-1739, and 2 certificates pertain to claims registered by Samuel and Chatfield Osborn at a land office in Fort Wayne, Indiana, in 1838. Three medical lecture tickets (1804-1805) and a certificate (August 7, 1806) relate to Dr. Thomas Osborn's medical career, and fragments include an undated item with a lithograph portrait of George Washington surrounded by Civil War-era military paraphernalia and a brief poem.

A notebook contains recipes and instructions for medical treatments and additional notes and accounts, dated as early as 1797 and referring to events as late as 1874. A group of genealogical charts, copied letters, and notes (11 items total) provides information about members of the Fanning, Jagger, and Osborn families from the mid-17th to late 19th century. Two copies of a broadside regard the sale of items from Daniel H. Osborn's estate (March 5, 1867).

The Hinkley collection is comprised of an account book and exercise book owned by members of the Hinkley family of Georgetown, Maine, in the mid-18th and early 19th centuries. The materials pertain to John Hinkley's finances, Samuel P. Hinkley's finances and education, and religious poetry.

The Hinkley collection is comprised of an account book and exercise book owned by members of the Hinkley family of Georgetown, Maine, in the mid-18th and early 19th centuries. John Hinkley kept 125 pages of accounts from 1755-1779, Samuel P. Hinkley kept 3 pages of accounts from 1789-1805, and Samuel P. Hinkley recorded 56 pages of information about mathematics and navigational principles. The account book also has 8 pages of religious poetry.

The first 125 pages of John Hinkley's Account Book concern the period between June 1755 and May 1779, though most accounts are dated between 1755 and 1765. His double-entry records pertain to his purchases of chocolate, sugar, corn, meal, rum, molasses, and other foodstuffs, and some reflect his interest in a sawmill. Several aspects of the mill's business are covered, such as providing boards and hauling timber. John Hinkley frequently traded with other members of the Hinkley family, including Josiah Hinkley and Samuel Hinkley. The accounts are followed by 8 pages of religious poetry, with one poem attributed to Betsey Hinkley, and 3 pages of financial accounts that Samuel P. Hinkley sporadically recorded between December 1789 and June 1805.

Samuel P. Hinkley's Exercise Book, dated December 18, 1837, contains 56 pages of nautical navigational problems and exercises. Topics include plane sailing, traverse sailing, parallel sailing, middle latitude sailing, and Mercator sailing, as well as the method of ascertaining latitude by making observations. Hinkley recorded several case studies and accompanying exercises for each sailing method, and the book contains the mathematical calculations used to solve each problem. Some problems, particularly those in the traverse sailing section, are accompanied by tables. The last several pages are copied entries from an unnamed ship's log, originally recorded during a journey between Boston and Madeira in March and April 1824 and during an unspecified voyage in January 1824.

This collection is made up of 4 letters that D. Bell, Jr., wrote to his parents in England while traveling in Canada during the summer of 1777. Bell discussed his uncomfortable transatlantic voyage, his leisure activities in North America, his relationship with a woman back home, and other subjects. His letters contain brief references to the colonial "Rebels" and to General John Burgoyne.

The William Rawle letter book contains copies of letters that Rawle, a Loyalist, wrote to his sisters, mother, and stepfather from New York; Cork, Ireland; London, England; and Boulogne, France, between 1778 and 1782. Rawle commented on the progress of the war, local customs and politics, and his travels, among other subjects.

The William Rawle letter book (162 pages) contains copies of letters that Rawle wrote to his family from New York and Europe between 1778 and 1782. He most frequently addressed his letters to his sisters P. R. ("Adelaide") and A. R. ("Anna" or "Fanny"). Rawle occasionally wrote to his stepfather, former Philadelphia Loyalist mayor Samuel Shoemaker, with whom he had fled to New York, and to his mother, who had joined him in New York the following year. The letters sometimes appear out of chronological order, and the first 2 pages are missing. Rawle often signed his letters "Horatio."

Rawle's earliest letters to his sisters, dated around 1778, describe his journey from Philadelphia to New York on the sloop Harlem in mid-June 1778, a journey of nearly 2 weeks. After his arrival, he mentioned Long Island residents' preoccupation with politics and his own confidence in British success against the French fleet in the Caribbean. He commented most frequently on his social life, his concern for family members in Philadelphia, and news of acquaintances. In 1781, he began to discuss his desire to leave for England. He sailed on June 13, 1781, and arrived in Cork, Ireland, on July 15, 1781, where he wrote 2 letters to his mother, providing his impressions of the country. He also noted Irish support for the American Revolution, and expressed surprise at the freedom with which the Irish voiced their opinions. By October 1781, he had arrived in London, where he wrote about his activities, including his studies at the Middle Temple. Rawle also noted some differences between life in England and North America, and developed a desire a return to Pennsylvania, despite his Loyalism. His final letters pertain to his decision to go to France in 1782 and note his arrival in Boulogne that summer. Rawle's letters are followed by a page of brief biographical notes and a 2-page poem entitled "On the Death of a young Lady."

This log book pertains to the voyage of the bark Neptune from Philadelphia, Pennsylvania, to Mauritius and back to Philadelphia between May 1789 and August 1790, as well as multiple voyages of the schooner Federal between Pennsylvania and the Caribbean between March 1791 and November 1791.

This log book (around 200 pages) pertains to the voyages of the bark Neptune from Philadelphia, Pennsylvania, to the Isle of France (present-day Mauritius) and back to Philadelphia from 1789-1790 and voyages of the schooner Federal between Pennsylvania and the Caribbean in 1791. The log entries are written in a pre-printed The Seamen's Journal Book (London, 1785), with sections for each day's measurements and remarks.

The log entries from the voyages of the Neptune (which comprise the bulk of the volume) and the Federal are typically notes on the wind direction, ships' courses, and ships' positions. Additional prose remarks concern weather conditions, the sighting of land, encounters with other ships, and anchorage at a port or harbor. The log has gaps during the Neptune's stay at the Isle of France and during the Federal's time in Caribbean and United States ports.

The first page of the volume, preceding the printed title page, has calculations involving an epact. The book's final pages contain entries from one of the Federal's voyages and additional notes about the Neptune's time at the Isle of France in December 1789 (particularly regarding a thunderstorm). A sheet of paper laid into the book contains notes about an unknown vessel's anchorage at Saint Helena in May and December 1783.

This collection is primarily made up of correspondence between and addressed to members of the Gough family of Gort, Ireland, including George Stephens Gough; his wife, Jane Arbuthnot; and their children, Hugh, George, Rodolph, and Eleanor ("Nora").

The Correspondence series (740 items) largely consists of incoming personal letters addressed to Jane Gough, Viscountess Gough, and her son George. George Gough frequently wrote to his parents (most often his mother) throughout the 1860s, describing aspects of his education at Woodcote House in Henley-on-Thames, England; Eton College; and the University of Cambridge. He also commented on family news and his desire to join the military. George's later letters, written from the 1870s-1890s, concern his career with the British Army, which included service in England, India, and Africa; some of his letters from 1881 refer to political relations around the time of the First Boer War. He also wrote letters from Dresden, Germany, and from Switzerland.

Jane Gough received additional letters from acquaintances, including a group of letters expressing sympathy after George was wounded at the Battle of Abu Klea in January 1885. George Gough received letters from his siblings Hugh, Rodolph, and Nora, and from school friends and other acquaintances. One frequent correspondent, "Hubie," wrote throughout the 1860s, telling Gough about his experiences at Eton College and University College, Oxford.

The Diary (147 pages) recounts George Hugh Gough's travels in Canada and the United States during the fall of 1888. The volume covers the entirety of the trip up to Gough's return departure for Ireland, including ocean travel between Ireland and North America and railroad travel throughout Canada and the United States. Gough's entries regard daily activities, the scenery, historical context about places visited, and current events (such as the United States presidential election of 1888). The first page contains a list of visited locations and the distances between them. The final four pages contain a list of expenses incurred between September 28, 1888-November 15, 1888.

The George Barrell journal is a bound account entitled "Journal of a Voyage from Boston to Malaga in the Brig Venus and Return in the Schooner Louisiana by George Barrell." Along with Barrell's prose descriptions of life at sea and detailed depictions of Gibraltar and Malaga, the author drew 32 colored illustrations, primarily of landscapes and people he encountered on his journey. The account, which commenced on July 13, 1806, first chronicled the travels of the Venus to Gibraltar, Spain, via the Azores. Barrell made daily notations about the weather and often mentioned interesting occurrences; Spanish privateers, whom he detested, boarded the ship on several occasions, though the Venus also encountered friendlier British ships. By mid-August, they had arrived at Gibraltar, which Barrell described in detail on several pages, recording observations about the city and its people, including the weather, the Jewish population, local British officers, and local buildings. Following a quarantine period at Gibraltar, the Venus sailed to Malaga, about which Barrell also noted his observations. On September 28, 1806, he left on the Louisiana for New York City, but rough seas lengthened their journey to several months.

The journal also contains 32 color illustrations created by Barrell during the course of his travels. He often drew ships, landscapes, and various military officers seen along the Spanish shore.
