Prevailing diseases were catarrh, rheumatism and several severe cases of scurvy 'caused by the cold, damp and heavy state of the weather, and the 'wet state of the ship' at the start of the month.

CONVICT ATTITUDES TO THEIR NEW LIFE
Amongst the convicts were two men who had been held in London prisons in 1837. George Caddell
and John Cook were interviewed while in prison by John Ward who later gave evidence at the Molesworth Select Committee on transportation. -
Q. - Did you find that they were aware at all that if they committed offences in the colony they would be subjected to very severe punishment? -
A. - I do not believe that the agricultural prisoners that I spoke to, had any idea of that.
Q. - Did you find that the more educated class, for instance, the London thieves, had any idea of that description? -
A. - In Maidstone gaol I examined George Caddell
, who was under sentence of transportation for 14 years, for uttering; he had been in prison before, having been a year in Coldbath-fields; he told me that he knew nothing of the place where he was going to, for he had never read about it or heard any particulars; he thought that other prisoners were equally ignorant with himself; he did not particularly dread going out, because he did not know what he might meet with, and when he was in prison he knew what he must expect. In Aylesbury county gaol I examined John Cook, who was under sentence of transportation for life, for sheep stealing; he said he knew nothing about the place to which he was going; that he did not know how he might find it, but he thought it could not be worse than a prison.
