[1] While he was in his third year at Balliol, his father suffered financial ruin, and Mitchell had the unexpected task of finding a livelihood.

He switched courses from history to classics and secured a second-class honours degree which enabled him to gain appointment as a master at Eton in 1866, remaining there until compelled by ill-health to retire in 1901.

[3] A later Eton master, G. W. Lyttleton, who as a schoolboy had played cricket under Mitchell's supervision, considered him a philistine housemaster: "unless you were a dab at some game you cut no ice".

[6] Mitchell was a right-handed batsman, occasional wicket-keeper and right arm medium pace roundarm bowler.

Mainly associated with the Eton Ramblers, Oxford University and Marylebone Cricket Club (MCC), he made 57 known appearances in first-class matches.
