The documents in this series, previously located at ML A78-1, were purchased in 1884 from Lord Brabourne by Sir Saul Samuel, the Agent-General for New South Wales. They were transferred to the Mitchell Library in 1910 and were part of the accession which became known as the Brabourne collection. It is now not possible to reconstruct Banks' original arrangement. The series has therefore been arranged chronologically.
Sir Joseph Banks was the recipient of many letters requesting financial support, or his support in obtaining a position or promotion.
