SURGEON WILLIAM EVANS
William Evans kept a Medical Journal from 15 July 1836 to 5 January 1837 during the voyage from Deptford, Kingstown and Cork to Sydney. He joined the Earl Grey on 15 July 1836 at Deptford
On 25th July, the soldiers of the Guard joined the vessel. The Guard consisted of Lieut. Ronald McDonald of the 80th regt., Lieut. R. B. Hill, 41st regt., Quarter Master Potter 4th regt., Assistant Surgeon Graydon 50th regt., Assistant Surgeon Allman 4th regt., one Sergeant and 29 rank and file of the 28th, 50th and 80th regts., 5 women and 7 children. 
Cabin Passengers included Mrs. Macdonald, Mrs. Allman and Mrs. Potter.
DEPTFORD TO KINGSTOWN
They sailed from Deptford on the 27th July and reached Kingstown on the 14th August. On 16th August, 91 convicts were received from the Essex Hulk.
The following day the Earl Grey sailed for Cork arriving there on 21st August. On the 23 August, 192 convicts and 5 free boys, the sons of convicts in the colony were embarked. In total there were 384 people on board.
The Earl Grey departed Cork on 27 August 1836.
Between Cork and the latitude of Madeira there were a few slight cases of fever arising from the damp, crowded dormitory. After passing the Cape Verde Islands the heat became oppressive and on entering the rainy regions thirteen men were suffering from scurvy. William Evans thought scurvy and scorbutic dysentery seemed to arise partly from the impurity of the water but also from foul stagnant air between decks, combined with depression, anxiety of incarceration and sea diet. The water had been taken on at Deptford with very little care and sometimes at improper times of the tide, though Government regulations were imperative on this head.
CROSSING THE EQUATOR
On the evening of 1 October they crossed the equator with a fine breeze from south southeast and passed rapidly through the south east trades, reaching the Tropic of Capricorn in 11 days from the line. There were now 30 men suffering from scurvy and on 19th October William Evans recommended the master to call at the Cape for refreshment, experience having taught him that 'lime juice and nitrate of potash are mere prophylactics' and that fresh meat and vegetables were the only sure means of ensuring health for the rest of the voyage.
CAPE OF GOOD HOPE
At 5pm on 4 November the Earl Grey anchored in Simon's Bay, where they remained for eight days. They received fresh beef, mutton and vegetables and took on board 5 live bullocks and 60 sheep. In less than a fortnight, thirty men who had been bed ridden were convalescent and continued to improve in spite of the weather.
Eight prisoners were taken on at the Cape - Jacob alias Jacob Asolie;
Edward Henry Elphie
Joseph Job Broadbent
Although he had not had the chance to examine the convicts, Surgeon Bailey R.N., at the Cape of Good Hope referred to the prevalence of scurvy on the Earl Grey in Memorandum on Scurvey by Surgeon Bailey R.N. Superintendent of the Somerset (Civil) Hospital at the Cape of Good Hope.
On 20th December 1836, Cape Otway was sighted and soon after the north end of King's Island. The following day they passed through Bass Straits with a fine breeze from the westwards.
On 31 December 1836 the Earl Grey reached Sydney after a voyage of 18 weeks from Cove of Cork. The weather was fine and by the time they reached Sydney. The convict indents report three deaths during the voyage - Charles McCarthy, Michael Coyle and Patrick Bryan,
The Military Guard were landed and marched to their barracks on the 2nd January 1837. 
The convicts remained on board where a muster would have taken place. The indents include name, age, education, religion, marital status, family, native place, occupation, offence, date and place of trial, prior convictions and physical description. There are occasional notes about dates of death, pardons and tickets of leave but no details of where the men were assigned. 
They were landed 'at the point' on 18th January 1837. According to the surgeon, there was not one of the 288 convicts who were landed who could not walk to the Hyde Park Convict Barracks to be inspected.
