    Warns travellers of the dangers of eating adulterated pickles in Heidelberg hotels. Urges the traveller that, if he cannot obtain the services of a toxicologist, then he should 'immediately attempt to detect the presence of copper' in the pickles. The suggested method for detecting copper is to 'offer the lowest silver coin in your possession, and to ask for change for that amount'; this will provide a measure of how much copper the pickles contain.
