[Matthias Jacob Schleiden and the Meetings of German Natural Scientists and physicians].

Making use of two non published and hand-written documents it will be described the travel of the botanist M. J. Schleiden (1804-1881) from Jena to Nurnberg in September 1845 to the 23rd Meeting of the German naturalists and physicians, his stopovers and acquaintances. About this journey Schleiden wrote a little journal, and in November 1845 he had given a lecture ("Pawlowna-lecture") in Weimar about this congress. Also it will touch on Schleidens first years as university teacher at Jena likewise his participation in other meetings of the naturalists in the following years.
