Surgeon James Rutherford
James Rutherford kept a Medical Journal from 8 November 1832 to 9 May 1833.....
Of 236 convicts originally embarked eighty were received at Woolwich and 156 at Sheerness. I did not notice anything peculiar in their state of health or anything in their general condition except that some of them seemed to feel the want of flannels which they said they had been long accustomed to wear. 
There was an outbreak of cholera on board as well as scurvy. James Rutherford remarked on a symptom of scurvy he called spontaneous salivation which he had read about, and which he thought may have also affect those who engaged in religious fasting. He treated this symptom using a mixture of nitras potassa dissolved in equal parts of vinegar and lime juice, as used by Charles Cameron surgeon on the Ferguson in 1829.
James Rutherford went into great detail in his closing notes regarding the outbreak of cholera...The case called cholera asphyxia in the summary at the end of the journal, occurred at Sheerness a few days after the embarkation of the prisoners, and was officially reported a fortnight before the ship sailed from that place. In my report on that case, I said that the patient died of a disease attended with symptoms strongly suspicious of cholera and this cautious mode of giving a name or rather declining to give any name to that isolated case of obviously most alarming disease which exhibited at its very commencement every stymptom of malignant cholera that I am aware of, I adopted in order not to excite alarm believing as I did that the diorder was not importd with the prisoners but that it was occassioned be it cholera or not by the circumstance of the man having been deprived so he himself stated of flannels which he had been long accustomed to wear at the moment when he put on new clothes and was about to embark on board a convict ship not yet perhaps sufficiently aired and dried to preserve properly the health of a number of persons necessarily confined to a limited space within her sides.
For that a disease strongly resembling malignant cholera if not a mitigated form of that diease itself, might, independently of the ordinary cause of cholera whatever that may be, arise, at an early period after the embarkation of prisoners especially in the damp and foggy season of the year, on board such a ship must taken up after being for years comparatively uninhabited but occupied for the stowage of all sorts of cargo and probably before she was sufficiently dried and aired for the preservation of health in her crowded condition, when the breath and exhalations from the surface of so many individuals assembled together would greatly contributs to augment the damp of their prison, I hardly entertained a doubt.
The singledeath on the Mangles, that of William Buck, occurred while the ship still lay at Sheerness.
James Rutherford was also employed as surgeon on the convict ships Regalia in 1826, Pyramus in 1832 and the Hooghley in 1834.
A Visitor's Impression
Thomas Rolph gave the following account of his visit to a convict ship in November 1832 .......
We were detained some time at anchor, opposite Ryde, from the prevalence of adverse winds; the motion of the ship, when at anchor, in a rough sea, is extremely disagreeable. From our detention, an opportunity was afforded me of visiting a Convict ship, then taking in stores at Portsmouth. There were arrangements in her, for conveying two hundred and eighty criminals to New South Wales. The manner in which the ship was fitted up, combined security with comfort. The holds, in which the convicts sleep, were commodious: their allowance of food very liberal, and of the best quality, and every indulgence, consistent with their safety, is extended towards them, if their conduct is orderly and well behaved. The unfortunate creatures were taken on board the ship, during our stay at Portsmouth: they gave three hearty cheers as they left the land of their fathers; most of them for ever. The government, willing to show them every kindness, ordered the ship to remain off land for ten or twelve days, in order that they may communicate with their friends.......
