QUOTE : Good heavens!” I said. “Strychnine and vitriol in beer?”<br /><br />“And in gin too. Enough to impart hallucinations and a nasty disruption of the bowels. And I have seen far worse: indianberry – very toxic – added to beer to make it more intoxicating. Custard flavoured with laurel – a mortal poison; pepper made from floor sweepings, comfits from china clay. Double Gloucester cheese coloured with red lead. Lead, copper, mercury, arsenic – deadly, all – they are everywhere. I myself can attest that lead salts taste quite delicious.
