Will use new English edition [5th, of Origin] in preparing for [4th] German edition. Bronn’s translation of Origin in the title as "Entstehung" is not so precise as "Ursprung" would be.

Recounts the trip back from St Petersburg – visits to botanic gardens and museums throughout Western Europe.
Pleased that CD admired Bentham’s address [see 6793]. JDH had read it in MS and modified some very heterodox passages about insularity. CD has hit the flaw in it.
