How Stevenson describes him:
"the neat, bright doctor with his powder white as snow, and his bright, black eyes and pleasant manners"
The role he plays in Treasure Island:
A decent, honourable man, who is practical and sensible even when things get tough. Due to his commonsense the treasure is found and brought safely home.
What he has to say:
"It was an interesting little trip - slight bit of bother on the way, but nothing serious."
