Congratulations with the Fridtjof Nansen award. Was in Stockholm and celebrated Wittrock. Is travelling to Cherbourg and the biological station there to do some work; is Foslie interested in having calcareous algae from there. Expresses his opinion about Henckel's major work on phytoplankton in the Caspian Sea, that he is too irresponsible in his work.
