"[on the collapse of Ayr Bank] Englishmen of course suspected a plot by those canny Scots. ‘The deel away wi ye all ye English Pudding boys ken ye nae that Paper is lighter of digestion than Gold’, cries the Scot on the broomstick in the London satire reproduced here, as he zooms back to Scotland with bags full of English gold, leaving chaos and destruction in his wake." (Jonathan Conlin, Critical Lives-Adam Smith)
