CD had acted as treasurer for the Down National School accounts, but had passed on the responsibility to Robinson in 1868. In December 1868, Robinson went to Ireland for three months; CD had expressed concern about school subscriptions in Robinson’s absence (see Correspondence vol. 16, letter to J. B. Innes, 1 December 1868) and evidently took over the treasureship again in 1869 (see letter from John Lubbock, 8 February 1869, and Bromley Public Library, Downe National School Annual Report 1869 (P123/5/7)).
