How did the seaman react to Dr. Livesey's advice?

From the text:

‘Were you addressing me, sir?’ says the doctor; and when the ruffian had told him, with another oath, that this was so, ‘I have only one thing to say to you, sir,’ replies the doctor, ‘that if you keep on drinking rum, the world will soon be quit of a very dirty scoundrel!’
The old fellow’s fury was awful. He sprang to his feet, drew and opened a sailor’s clasp-knife, and balancing it open on the palm of his hand, threatened to pin the doctor to the wall.
