Declines the honour of writing a biography of Leopold von Buch, on grounds that he would not do it well; nor does he hold Buch so high as the world at large does.
Thanks ES for his note [missing]. CD had understood that what was wanted was a eulogy [of Leopold von Buch] combined with historical criticism, after the French practice. Agrees that historico-critical sketches of work of great foreigners have a place in Philosophical Transactions and wishes he had taste and capacity for it.
Is unequal to taking chair as President of Natural History Section of BAAS meeting in Liverpool. Very little fatigue or excitement brings on swimming of head, nausea, and other symptoms.
CD and Hooker suggest Sir John Richardson for Royal Medal. Other suggestions are George Bentham, Joseph Prestwich, Albany Hancock.
Would rather not serve on Royal Society committee [for a North American exploring expedition]. Suggests subjects for geological investigation.
