Chapter 27: The timeline of the concluding chapter is odd. September

9, 1861 the party is at the end of North Devon. The next day (September 10) they are picked up by the Danish whaler. Ten days later (September 20) they arrive in Denmark. The 13th of the same month (September 13? October 13?) they reach London. July 15 (1862?) Clawbonny attends the Royal Geographical Society of London meeting. For this to astonish the learned assembly it would need to be two days after their arrival in London rather than 9 months.
