Dr. Macfarlane was alert and vigorous. His white hair set off his pale and placid, although energetic, countenance. He was richly dressed in the finest of broadcloth and the whitest of linen, with a great gold watch-chain, and studs and spectacles of the same precious material. He wore a broad-folded tie, white and speckled with lilac, and he carried on his arm a comfortable driving-coat of fur. There was no doubt but he became his years, breathing, as he did, of wealth and consideration; and it was a surprising contrast to see our parlour sot—bald, dirty, pimpled, and robed in his old camlet cloak—confront him at the bottom of the stairs.
