Tono-Bungay by H.G. Wells — Read

I seem to remember very quick changes of mind after that lunch. The muzzy exaltation of the unaccustomed stimulants gave way very rapidly to a model of pellucid and impartial clairvoyance which is one of my habitual mental states. It is intermittent; it leaves me for weeks together, I know, but back it comes at last like justice on circuit, and calls up all my impression, all my illusions, all my willful and passionate proceedings. We came downstairs again into that inner room which pretended to be a scientific laboratory through its high glass lights, and indeed was a lurking place. My uncle pressed a cigarette on me, and I took it and stood before the empty fireplace while he propped his umbrella in the corner, deposited the new silk hat that was a little too big for him on the table, blew copiously and produced a second cigar.

It came into my head that he had shrunken very much in size since the Wimblehurst days, that the cannon ball he had swallowed was rather more evident and shameless than it had been, his skin less fresh and the nose between his glasses, which still didn't quite fit, much redder. And just then he seemed much laxer in his muscles and not quite as alertly quick in his movements. But he evidently wasn't aware of the degenerative nature of his changes as he sat there, looking suddenly quite little under my eyes.
