The system of management of the convicts differed little in that I had adopted on former occasions - ventilation and cleanliness forming the chief features while the formation of cheerfulness and the affording of all possible occupation to the convicts was practised as much as circumstances would allow; the results were on the whole satisfactory, though I think that more cases requiring medical treatment occurred than I had previously met with; this remark more particularly applied to the month of October during which period the change of climate was sudden and the weather particularly unfavourable to cleanliness, exercise and comfort in general. It was under the last mentioned circumstances that symptoms of scurvy manifested themselves in a light grade and but with a single exception the disease gradually wore away as the weather improved.
