Breve Trattato di Geografia is a 55-page, 17th-century Italian work on celestial and terrestrial geography, including several maps and diagrams of the world. The treatise is divided into four primary sections and, within them, individual chapters. Early chapters in the book mention the zodiac and celestial features, while later chapters focus on the world's landmasses and degrees of latitude and longitude. The latter half of the volume contains several hand-drawn maps that depict the contemporary view of the world on several scales and according to different projections. One map of the world shows North and South America and "Terra Australe Incognita," while another map of North and South America is labeled "Mexicana" and "Peruana," respectively. Azimuthal projections of Africa and Asia and of the northern hemisphere and a map of Italy showing the location of Rome are also included.

The Henry Vignaud papers are made up of letters, manuscript notes, and published works concerning Vignaud's diplomatic career and scholarly life in Paris during the late 19th and early 20th centuries. Letters and notes by his correspondents and fellow “Americanistes” Pierre Margry and Henry Harrisse comprise the bulk of the collection. The following books include manuscript items related to Henry Vignaud, many of which are tipped into or otherwise affixed to the volumes: Inventory of Henry Vignaud manuscripts located in books at the William L. Clements Library.

The Henry Vignaud papers are made up of letters, manuscript notes, and published works concerning Henry Vignaud's diplomatic career and scholarly life in Paris during the late 19th and early 20th centuries. The collection is divided into four series: Henry Vignaud, Pierre Margry, Henry Harrisse, and Miscellaneous. Groups of correspondence, writings, printed materials, and biographical portraits are arranged within each series.

The Henry Vignaud series includes incoming and outgoing letters, manuscript notes, and published works related to Henry Vignaud.

The Correspondence subseries mainly consists of letters Vignaud received between 1866 and 1922 regarding his diplomatic work and academic interests. Correspondents, such as Pierre Margry and Henry Harrisse, often discussed articles and other publications about North American history. One 496-page letter book contains copies of Vignaud's outgoing correspondence from February 25, 1876, to June 1, [1888]. Written in both English and French, these letters relate to his appointment as secretary for the United States legation in Paris. The letter book contains a chart comparing the sizes and expenditures of the standing armies of European countries (p. 198) and a floor plan for the United States legation's new offices (p. 343).

The Writings subseries contains notes, speeches, and manuscript books by Henry Vignaud. He compiled notes about topics in American history and composed biographical sketches of Henry Harrisse. He entitled his manuscript books Lettre de Toscanelli à Martins (Texte et Traduction) and Notes de Ximenes sur la Lettre de Toscanelli. Additionally, his papers include the bottom portion of a colored map depicting the French-German border and a description of plans for an arc de triumphe to stand over the "Monument du Gen. Lafayette," accompanied by a photograph of the model of the monument. The second photograph is a of mock-up a statue of George Washington and Lafayette shaking hands; the statue now stands in Moringside Park,New York City. Both photographs are signed by [Frédéric-Auguste] Bartholdi.

The Writings of Ferdinand Denis, a fellow Americaniste and future librarian of the Saint Geneviève Library in Paris, consist of his manuscript notes on topics related to Portuguese exploration and colonies, particularly in South America.

The Printed Materials subseries includes articles that Benjamin Franklin Stevens wrote about unpublished manuscript collections in European archives and specimen pages from his annotated facsimile edition of Christopher Columbus: His Own Book of Privileges 1502…. Additional materials dated between 1895-1896 pertain to a legal case involving the former American consul to Madagascar, John L. Waller.

The Pierre Margry series of letters, writings, and other items relates to Margry's scholarly work on North America. The bulk of the Correspondence subseries comprises 381 incoming letters between June 1839 and October 1889 about his academic interests. Margry also composed Writings on various topics, such as Isle Royale, Canada, and Detroit. François-Edme Rameau de Saint-Père and Gabriel Gravier wrote Biographical Sketches about Pierre Margry shortly after his 1894 death; 4 engraved portraits of Margry accompany the biographies.

The Henry Harrisse series contains materials similar to those in the Pierre Margry series. The Correspondence subseries includes 11 letters, 3 undated and 8 sent between November 1866 and January 1904, Harrisse wrote about his academic work, discussion of publications by his colleagues, and his efforts to locate specific maps. The Writings subseries contains extensive manuscript notes related to his publications about the European discovery and early exploration of North America. This interest continue to be reflected in the Biographical Portraits subseries, which includes notes and proofs for Harrisse’s work on “Americus Vespuccius” and on the sixteenth-century explorers John and Sebastian Cabot, as well as a 1-page account of Harrisse written by John Johnson (June 23, 1891); Henry Vignaud's writings on Harrisse are located in the Henry Vignaud series.

The Miscellaneous series includes 13 additional letters, 3 postcards, 2 funeral invitations for Sigismond-Joseph-Marie-Louise de Pourcet, baron de Sahune and Antoinette Helin, an invitation to a ceremony honoring the 100th anniversary of the Louisiana Purchase on December 18-20, 1903, and other miscellaneous notes.

"Elements of Navigation," a manuscript adaptation of John Robertson’s work of the same name, provides instruction and practical exercises in arithmetic, geometry, trigonometry, geography, astronomy, and navigational principles (781 pages). The volume is illustrated with mathematical diagrams. It also contains a 1785 copy of a ship's log for a 1772 voyage from England to Madeira (21 pages). The book is divided into 14 primary chapters, 11 of them preceded by an ink or watercolor illustration of buildings, ships, and places, such as the watercolor drawings "The Desire in a Storm" and "A west View of Islington, old Church." (See below for complete list.) Several chapters are further divided into sections, and most chapters or sections are followed by problems, questions, case studies, answers, and explanations. Please see the box and folder listing below for a table of contents.

The volume begins with explanations of basic mathematical principles, including arithmetic operations, decimals and fractions, roots and powers, notation, and "Tables of English Money, Weights, and Measures" (pp. 9 verso-10 verso). This chapter is followed by theorems and problems of geometry and trigonometry. The subsequent section on geography contains prose explanations of the discipline's foundations, such as the shape of the Earth, the concept of latitude and longitude, and the currently known world. Remarks on the continents are accompanied by tables showing major countries, principal cities, rivers, and mountains. The tables for North and South America are split, and individual states within the United States are identified as "countries," as are California, New Mexico, Old Mexico, Louisiana, Canada, New Britain, New Wales, and others. Introductory geographic material also includes content on winds, tides, and bodies of water. A segment on "chronology" introduces several scales for measuring time, and explains the reasoning behind concepts such as the leap year and the "Golden Number" (pp. 147-147 verso).

The remainder of the work focuses on the art of maritime navigation. Several topics include: the calculation of compound courses, oblique and windward sailing, sailing in currents, and globular sailing. The sections devoted to each topic are comprised primarily of rules or theorems, exercises, and illustrations of practical applicability. A chapter on "spherics" introduces spherical geometry and trigonometry. Two chapters on astronomy explain concepts in "star astronomy," "terrestrial astronomy," and "spherical astronomy," such as the composition of the Solar System, planetary movements, and mathematical applications. The final 80 pages contain information on the art of sailing and expand on principles previously discussed. These pages include instructions on how to calculate the location of a ship at sea, make necessary observations, and correct a ship's course, among other similar topics.

The final 21 pages consist of a log from an unknown ship traveling from England to Madeira in 1772, transcribed by James West in 1785. Between July 2 and July 11, the log contains notes on the weather, wind direction, and general remarks of occurrences on board as the ship prepared for its journey at Deptford, London. On one occasion, the author mentioned a sailor being disciplined for drunkenness (July 3). Between July 12 and July 28, the log documents the weather, wind direction, ship's location, use of various sails, and other information compiled throughout the course of each day. The ship arrived at Madeira on July 28. The log is followed by a brief note by James West concerning the location of Funchal, Madeira.

The non-mathematical illustrations separating the book's chapters are done in ink or watercolor, and depict rural scenes and sailing ships.

This volume contains excerpts from correspondence, reports, and treatises concerning the relationships between the United States, Great Britain, France, and Spain during the Revolutionary War era. Two of the five excerpts originated from letters written by Silas Deane, an American agent in France; the other three narrate Benjamin Franklin's dealings with the French court, report on the British Army's finances, and analyze available options for amphibious military action. A later owner added brief biographical notes on the key Americans referenced within the volume.

This volume (117 pages) contains excerpts from correspondence, reports, and treatises concerning the relationships between the United States, Great Britain, France, and Spain during the Revolutionary War era. The first two segments (pp. 1-8 and pp. 9-33) are extracts of "intercepted letters" from Silas Deane to Brigadier General Samuel Holden Parsons (May 14, 1781) and Robert Morris (June 10, 1781) concerning diplomatic relations between the United States and the three major Continental powers (England, France, and Spain). Deane concentrated on the possible motives of France in assisting the American rebellion, noted the historical animosity between France and Great Britain, and shared his suspicion that France merely wished to see Great Britain's power diminished. He also questioned Spain's supposed neutrality and urged Parsons and Morris to consider reconciliation with Britain. The second letter focuses heavily on economic arguments, while the first primarily considers international politics and power relations.

The next excerpt is a third-person account of "Doctor Franklin's representations to the Court of France" (pp. 34-37), which recounts the American response to a recent French proposal. The summarized response cites the United States government's continuing desire to achieve full independence from Great Britain and its reluctance to accept the presence of large international military forces on its soil. Franklin also discussed French loans to the United States and reported his responses as the wishes of the United States Congress. The fourth, and lengthiest, excerpt, entitled "Extracts from the seventh report of the Commissioners of Public Accounts" (pp. 38-82), reflects the finances of British forces in North America from January 1, 1776-December 31, 1781. The report, issued on June 18, 1782, and later published, discusses funding for "extraordinary services of the Army" and notes specific amounts of money owed and supplies used during the Revolution.

The final essay, entitled "On Conjunct Expeditions" (pp. 83-114), discusses Great Britain's naval strength and posits a possible strategy for amphibious warfare combining infantry and naval forces. The treatise mentions several previous battles and examples and considers the drawbacks and benefits of these tactics. The essays are followed by brief biographies of Silas Deane, Samuel Holden Parsons, Robert Morris, and Benjamin Franklin, adapted from A Universal Biographical Dictionary, Hartford. S. Andrews & Son, 1856 (pp. 115-117).

This copy of Daniel Fenning's A New System of Geography (2 volumes, London: 1771) contains additional tipped-in maps, as well as manuscript notes by Richard Washington, who owned the books in the late 18th century.

This copy of Daniel Fenning's A New System of Geography (2 volumes, London: 1771) contains tipped-in maps, as well as manuscript notes by Richard Washington, who owned the books in the late 18th century. Additional notes in the first volume indicate that the books were given to F. G. O'Reilly by T. B. Tucker in St. George's, Bermuda, on December 14, 1837. Most of the notes are written directly into the volume, with a few appearing on pages tipped into the volume; some are dated as late as the early 1790s. Washington's notes appear most frequently in sections related to North America, the Pacific Ocean, and Europe. Many provide statistics about geographical locations, including population (often divided by race), imports, and exports. His notes about North America mention Native American tribes and United States independence. Washington also provided additional information about Pacific islands, based on the voyages of James Cook.

Sir Walter Raleigh's A Discourse of the Peace with Spain and retayning of the Netherlands is a 49-page manuscript treatise intended to persuade King James I to maintain a positive relationship with the Netherlands during peace negotiations with Spain in 1602.

Sir Walter Raleigh's A Discourse of the Peace with Spain and retayning of the Netherlands is a 49-page treatise, bound in vellum, intended to persuade King James I to maintain a positive relationship with the Netherlands during peace negotiations with Spain in 1602. Raleigh outlined the reasons for his belief that England should accept an alliance with the Netherlands following a thaw in relations with Spain and discussed relationships between major European powers.

This 238-page volume contains an unknown writer's opinions on the Revolutionary War and proposed military strategies, composed September-October 1776 and February 1778. Among other topics, the author discussed the relationship between land and naval forces and their relative strengths, explained possible ways in which economic affairs might affect the progress of the war, and promoted a strategy of dissolving the unity of the colonies. This volume belonged to Henry Dundas, 1st Viscount Melville, and includes his bookplate.

This 238-page volume contains an unknown writer's opinions on the Revolutionary War and proposed military strategies, composed September-October 1776 and February 1778. Among other topics, the author discussed the relationship between land and naval forces and their relative strengths, explained possible ways in which economic affairs might affect the progress of the war, and promoted a strategy of dissolving the unity of the colonies.

The volume is divided into two primary sections, with the author offering his thoughts on the war in late 1776 (pp. 1-146) and in early 1778 (pp. 147-238). Introductory remarks at the beginning of the first section suggest that the author intended his treatise for members of the British government. He focused on financial and economic affairs, such as the colonies' different currencies, the effects of privateering, and the difficulty of funding a war. In addition, he presented detailed proposals for British action, often revolving around a strategy of dissolving the colonies' confederacy. Some suggestions focused on specific cities or colonies.

The second section of the volume contains similar thoughts and strategies, with a focus on the differences between land and sea power. Though the author believed a British victory unlikely, he encouraged the government to focus on naval actions rather than land forces. Despite his skepticism, he concluded by affirming that the rebellion could be defeated by disrupting colonial unity and conquering Georgia by military force.

This volume belonged to Henry Dundas, 1st Viscount Melville, and includes his bookplate.
