Note 63 — Chapter VI · James Watt, Mathematical Instrument Maker.

When the Lowlanders want to drink a cheering cup, they go to the public-house, called the Change-house, and call for a chopin of twopenny, which is their yeasty beverage, made of malt, not quite so strong as the table-beer of England.... The Highlanders, on the contrary, despise the liquor, and regale themselves with whisky, or malt spirit, as strong as Geneva, which they swallow in great quantities, without any signs of inebriation: they are used to it from the cradle, and find it an excellent preservative against the winter cold, which must be extreme on these mountains.—Smollett, ‘Expedition of Humphry Clinker.’
