I want to know the answer to the following question:
Where was the book, On the Origin of Species first offered for sale?
All the background I'm provided with is that "The third edition came out in 1861, with a number of sentences rewritten or added and an introductory appendix, An Historical Sketch of the Recent Progress of Opinion on the Origin of Species, while the fourth in 1866 had further revisions.". Is that enough to answer the question?
Answer: no
