George Roberts kept a Medical Journal from 15 April to 10 September 1836.....
The prisoners when they came on board, were apparently healthy although they seemed in a low state from deficient nourishment. The Waterloo weighed anchor almost immediately the convicts were embarked and although the weather was fine they still suffered much from sea sickness which caused great debility. They were also unaccustomed to cocoa and were unable to use it. There was little illness amongst the prisoners during the voyage, just a few trifling complaints, never more than 5 or 6 at a time. 
Passengers included Major Cotton, Mrs. Cotton and 4 children.
Lieut. Mackay of 28th regt., 20 rank and file of the 28th and 9 of the 50th regiment; 7 women and 5 children.
The Waterloo departed Dublin on the 21st May 1836.
At 8 o'clock every morning the prisoners were ordered upon deck and remained until twelve when the prison was thoroughly cleaned and freely ventilated. The prison decks were either dry scraped or dry stoned. Lime juice and sugar were issued in the proportion of an ounce of each to a man mixed in a pint of water and one half given fore and afternoon . This was continued during the period that the ship was passing through the tropics and on getting to the southward and eastward when the temperature became much colder an allowance of wine was added. The voyage was without a symptom of scurvy and the prisoners were landed in excellent health.
The four men treated by George Robert's who were mentioned in his journal were:
William Johnston - A stout athletic man with a pale anxious countenance
John Honan - Of a weak habit of body, occasioned from irregular habits.
John Lawler - Of a scrofulas habit of body.
John Hassen - Naturally of a weak habit of body and shattered constitution from previous bad habits.
