This may be illustrated by the following anecdote: A certain scavenger went into the perfume-sellers' bazaar, and, smelling the sweet scents, fell down unconscious. People came round him and sprinkled rose-water upon him and held musk to his nose, but he only became worse. At last one came who had been a scavenger himself; he held a little filth under the man's nose and he revived instantly, exclaiming, with a sigh of satisfaction, "Ah! this is perfume indeed!"
