 Jamison had returned to Sydney aboard the Hercules in June 1802 after an eventful voyage from London (he had been forced to change ships in Rio de Janeiro because of a heated dispute with the master of his original vessel).Once ensconced back in Sydney, Jamison proved to be a diligent and capable medical practitioner.He was hampered, however, by a perpetual paucity of surgical supplies and assistants, about which he complained frequently to the authorities.
