How do the three friends describe to each other their maladies?

We were all feeling seedy, and we were getting quite nervous about it. Harris said he felt such extraordinary fits of giddiness come over him at times, that he hardly knew what he was doing; and then George said that he had fits of giddiness too, and hardly knew what he was doing. With me, it was my liver that was out of order. I knew it was my liver that was out of order, because I had just been reading a patent liver-pill circular, in which were detailed the various symptoms by which a man could tell when his liver was out of order. I had them all.

We've pretty much covered J. George, on the other hand;

George fancies he is ill; but there’s never anything really the matter with him, you know.

“Rest and a complete change,” said George. “The overstrain upon our brains has produced a general depression throughout the system. Change of scene, and absence of the necessity for thought, will restore the mental equilibrium.”

George has a cousin, who is usually described in the charge-sheet as a medical student, so that he naturally has a somewhat family-physicianary way of putting things.
