In June 1810 he stepped down as rector and presented 'De perscrutatione mentis humanae maximum medico faciente emolumentum' (the investigation of the human mind, the greatest contribution made by the physician), in which he urges physicians to practise therapy.
  In 1806 Krauss was elected a correspondent, living in the Netherlands, of the Royal Institute of the Netherlands.
