As Ruhnken's reputation spread, many efforts were made to attract him back to Germany, but after settling in Leiden, he only left the country once, when he spent a year in Paris, ransacking the public libraries (1755). For work achieved, this year of Ruhnken may compare even with the famous year which Ritschl spent in Italy. In 1757 Ruhnken was appointed lecturer in Greek, to assist Hemsterhuis, and in 1761 _he_succeeded Oudendorp, with the title of ``ordinary professor of history and eloquence'', as Latin professor. <sep>, Pronoun: he <sep>, A: Ruhnken <sep>, B: Hemsterhuis
