Reports on settlements in Australia visited by Backhouse and Walker during 1833-1835, probably contemporary copies. The 'Australian dictionary of biography' has the following entry on the reports (vol. I, p. 45): 'They gave (Sir George) Arthur eight valuable reports on the penal settlements of Macquarie Harbour and Port Arthur, the Aboriginal establishments on Flinders Island...In New South Wales and its dependencies Governor Bourke encouraged similar work in 1835-37...Their reports were sent to London Friends and to the Colonial Office'.
