To Ernst Haeckel   2 September 1879

My dear Haeckel,

I shall be delighted to see you here on any day at any hour. But would it not be the best plan for you to sleep here? There is a train which leaves Charing Cross for Orpington Station, where at 4.54 I would have a carriage waiting for you, and you could return as early as you liked next morning.¹ As I cannot talk long with anyone I believe that I should by this means be able to see more of you than if you came down here in the middle of the day. But pray do exactly what suits you best, & let me hear.

Until we meet, yours very sincerely | Charles Darwin
