Financial account books of the Royal Society The series falls into two chronological groups. The first series contains the early financial accounts for the Royal Society, 1660-1768. Much of this material deals with the financial state of the Society during James West's Presidency, and represents the administrative work of the two Library Keepers/Clerks, Francis Hauksbee and Emanuel Mendes da Costa. The second series consists of cash-books and ledgers of the 19th and 20th centuries, 1867-1976. These deal with the Society's general finances, as well as its administration of the Government Grant and various Trust Funds. A third section contains copies of the Royal Society's Annual Accounts - both signed and unsigned. 1660-2004
