Apologises for long delay since receiving Smith's letter from Professor [Josef August] Schultes. Has been unable to find the 'Tilia' requested by Smith as he is too ill to go to the Stokenchurch area and it is not present in the Oxford Botanic Garden and there are no full specimens in Oxford herbaria. Describes another failed attempt to acquire it. The Botanic Garden has a plant of Mr Whitehead's 'Aconitum' but it is now too mature for Smith to obtain any information from a specimen.

Glad that MPH is vacationing with Mrs. Delevaux. Sorry about Charles Babbage's loss. Journey from Innsbruck. Meeting with Josef Fraunhofer. Georg von Reichenbach is dangerously ill. Met Captain Feilding and family. Itinerary for return journey via Hanover. Will visit caves of Bayreuth and J. W. A. Pfaff in Erlangen.
