John Drummond kept a Medical Journal from 29th March to 22 September 1828. Shortly after embarkation many of the prisoners became affected with slight bowel complains and catarrh. The surgeon attributed these complaints to the change in diet and clothing. Illness was increased by the extremely cold and damp weather that took place during the first two weeks after leaving Port. As they advanced further southwards cases of fevers and dysentery began to arise. During the latter part of the voyage the weather remained cold and damp with frequent gales. The men suffered much from the continual wet state of the prisons and sleeping berths. Owing to the faulty state of the ships decks, the prisons were often completely flooded. John Drummond made every attempt at cleanliness, scraping the decks each day and encouraging the men to keep themselves and their clothing clean. Any indulgence possible was granted to them which the safety and duty of the ship could allow. Schools were established and attended and with much good effort John Drummond had the satisfaction of landing all the convicts at Port Jackson, none having died on the voyage.
