The cashbook contains receipts from fees, 1714-1718, (folios 1-23), miscellaneous expenses, 1718, (folios 23 verso-31), "Accompt of what I have receiv'd of the rents of Kildonand", 1714-1718 (folio 36), and miscellaneous expenses, 1714-1717 (folios 41-72).

The volume is assigned to William Eccles on the grounds that it belonged to a doctor practising in Edinburgh, and that according to Sir Robert Douglas in ‘The Baronage of Scotland’, volume i, page 437, the estate of Kildonan belonged to William Eccles 'an eminent physician in Edinburgh'. An entry under miscellaneous expenses for 10 November 1718 (folio 29 verso), 'James Graduation' provides confirmation: according to Douglas, Eccles' son James was a doctor and the only medical graduation at Edinburgh in that year was of Jacobus Eccles on that day (see ‘Nomina eorum qui gradum Medicinae Doctoris adepti sunt’, page 1).
