SURGEON ALICK OSBORNE
Alick Osborne kept a Medical Journal from 22 July 1838 to 5 January 1839. He noted in his journal that the convicts were received in good health at Dublin and that the vessel sailed at a favourable period of the year.
departed Dublin on 8th September 1838.
The surgeon remarked that the scorbutic (scurvy) cases were noticed promptly and quickly yielded to his treatment of nitre and vinegar. He administered this remedy to all patients with boils, ulcers, or eruptions with good effect.
On the 18th November the Elphinstone was in latitude 48° south, longitude 30° east and on the 22nd November in latitude 25° south, longitude 36° east.
arrived in Port Jackson on 29 December 1838.
The prisoners were landed on Saturday 5th January 1839. Although they arrived at the hottest time of the year, there was little sympathy for newly arrived convicts and they were put to work as soon as possible. John Gannon, aged 55, did not survive long after arrival. Just ten days after landing, on 15th January, the hottest day of the year, he was working in the streets when he was taken ill. He was removed to the prisoner barracks and then to the hospital but died soon afterwards A coroner's inquest found that he had died to exposure to the sun and exhaustion.
