These are two manuscript copies of Marchetti's translation of Lucretius, Tito Lucrezio della natura delle cose.

William Badgley's papers form the bulk of the family's papers and consist of a book of legal notes and judgments, 1801-1826; legal commissions, 1823-1866; as well as circulars, petitions and correspondence for the Constitutional Association, 1834-1839. Other papers include family correspondence, 1823-1829, and deeds of sale, 1831-1852, of James Thompson Badgley.

Hardinge's papers are divided into two series: manuscripts and correspondence. The manuscripts comprise about 550 documents, reports, memoranda, etc. relating to Hardinge's work as a career soldier and administrator. The Indian phase of his career is the least well covered. Many of these documents were written by others, such as the Duke of Wellington or Lord John Russell, though they contain Hardinge's marginal notes. Papers on the British Army cover such topics as religious services for soldiers, 1823-1844; the organization and reform of military supply departments, 1822-1830; an inquiry into British military education, 1822-1829; and the organization of the Medical Department, 1812-1828. Material on the Home Army covers the period 1814-1850 while material on Ireland, 1816-1843, concern not only the militia, but also more wide ranging economic, social and political issues, such as the commutation of tithes. Papers on British North America, 1815-1844, concentrate on defence of the St. Lawrence Valley and the Maritimes, with special emphasis on canals (Rideau, Lachine, Welland). The strength, distribution, health problems and pay of troops in India, 1846-1847; the fortification of Aden, 1825-1847; and military matters pertaining to the West Indies, Bermuda, Australasia, South Africa, Mauritius, China, the Iberian peninsula and the Crimea are also discussed. It should be noted that the Australian papers also contain a considerable body of civilian population statistics. Hardinge's files also contain materials on military finance, particularly army estimates, 1826-1844; half-pay and pensions, 1812-1832; pay and allowances, 1827-1841; and the finances of the War Office, 1803-1847. Finally, a section of miscellaneous papers includes addresses by Hardinge, memorials of civil and military officers, cases of military discipline, proposals for new weaponry, and some documents on the reorganization of the government in 1827. The only items of personal interest concern the duel between Wellington and Lord Winchelsea, in which Hardinge was Wellington's second. The Hardinge correspondence is of much the same character as the manuscripts. It comprises over 2,000 letters, the largest blocks falling in the periods 1828-1831, 1842-1844, and 1852. There is a particularly substantial body of letters from Wellington and Lord Londonderry. Supplementing these papers is a microfilm of Hardinge materials in Cambridge University Library. These place more stress on the Indian period, with a large number of letters from Sir Robert Peel.

This material consists of business documents and correspondence reflecting the activities of the St. Lawrence Steamboat Co., mostly for the pre-1840 period, although there are documents dating to 1863. The major portion of the fonds, comprising 83 of a total 89 volumes, consist of freight books (1819-1833) and passage books (1822-1838). These logs provide information on passengers and goods carried between Montreal and Quebec, as well as other stops such as Chambly. The fonds includes information on fifteen steamboats and two barges, operated by the St. Lawrence Steamboat Company, which made voyages between 1819 and 1838. The data found in the vessel logs in the fonds include names of vessels, details on their crews, quantities of fuel aboard such as wood and coal, and the number of downbound voyages (that is, from Montreal to Quebec) and upbound voyages per seasons (generally from May through November). Lists of cabin and steerage passengers as well as descriptions and quantities of goods carried between Montreal, Chambly, Sorel, Trois-Rivieres, and Quebec are also sometimes included in the logs. The information also includes charges levied for passage and for freight as well as the names of consignors (shippers of goods) and consignees (receivers of goods, usually a merchant), as well as the destination address. The steamboats found in the fonds also frequently towed barges and brigs, whose names are sometimes recorded along with the charges levied. In addition to these vessel logs, the fonds also includes: account books, 1803-1818, 1844, 1851; wage books, 1826-1832-1835; bills of lading, 1812-1813; and letterbooks, 1827-1829, 1843-1863. One book of account pertains to laundering costs for the years 1819 to 1828; a journal (log book) for the “Lady Sherbrooke” for 1823 is also included. Finally, there is an inventory of furniture, bedding and wares onboard th steamers in 1829, 1831, and 1833, and an unrelated and incomplete pay list for dock workers dated September 1892.
