I should be glad to learn if you expect to be in Jena during the months of February & March next? I have some hope of being able, then, to fulfil my || long cherished intention of paying you a visit. You will possibly remember that I wrote you from London in the autumn of last year. Since that I have had the pleasure of reading „The Wonders of Life“ & beg to add my small mead of thanks for the valuable || assistance which this work has given to students like myself.
