After William Temple Franklin returned to Europe in 1792, he left oversight of his financial interests in America in the hands of his intimate friend and fellow land speculator, George Fox. A physician and member of the American Philosophical Society, Fox also took possession of the remainder of Benjamin Franklin's papers, which eventually passed through his son, Charles Pemberton Fox, to the APS. The Franklin-Fox Collection contains 98 items, consisting mostly of letters from William Temple Franklin to George Fox regarding land holdings and finances, and retained copies of Fox's letters to Franklin. The correspondence is fairly relentlessly focused on business matters and rarely contains personal comments, however there are occasional requests for books and two reference to the yellow fever epidemic of 1798 and the death of Benjamin Franklin Bache.

These are accounts of expenditures for various legal services rendered as magistrate, as well as some miscellaneous personal accounts.

A mineralogist and chemist associated with the University of Pennsylvania (1822-1828), William H. Keating was a central figure in the scientific community in Philadelphia during the 1820s and 1830s. Active in the American Philosophical Society and Academy of Natural Sciences, and a founding member of the Franklin Institute, Keating was official geologist on Stephen Harriman Long's expedition to the Great Lakes in 1823 and spent three years in the late 1820s surveying the mineral resources of Mexico. The William H. Keating notebooks include three cash books (daybooks of cash expenditures, 1830-1839) and a book containing surveys of Keating lands in Potter County, most undertaken by Silas McCarty for William's father John Keating (1801-1818). The surveys associated with John Keating are an interesting record of land investment and speculation in the northern tier of Pennsylvania. William Keating's meticulous cash books provide a detailed record of his domestic expenses, philanthropic involvements (donations to the Catholic Church, the Prison Society), his reading (newspapers and books are listed individually), socializing (theatre tickets, Assembly fees), and a variety of miscellaneous expenditures ranging from purchase of a lithograph of Dugald Stewart to a table lamp from C. Cornelius. His accounts also include lists of servant's wages and wages for washerwomen.
