From 'Visits Sheffield' part of 'Memoirs Of My Life And Writing'

Mr. d'Alembert relates, that as he was walking in the gardens of Sans Souci with the King of Prussia, Frederic said to him,

Do you see that old woman, a poor weeder, asleep on that sunny bank? she is probably a more happy being than either of us.'

The king and the philosopher may speak for themselves; for my part I do not envy the old woman.
