The original letters below were amongst a group of documents on display at 50 Albermarle Street on the 24th November 2009 for the 150th anniversary of 'Publication Day'.

Reproduced with special permission of the John Murray Archive  Edinburgh  they include, below, the Rev. Whitwell Elwin's letter who reviewed the 'Origin' for John Murray III and recommended that Darwin should write a book on pigeons.
The letter, below left, is in Darwin's own hand, written on Publication Day 1859 to John Murray.

The letter, below right, is another Darwin letter pointing out the interest of each of the twelve chapters of 'Origin'.

Also on display was one of the original manuscript pages owned by the Keynes family and a first edition of 'On the Origin of Species' which was John Murrray III's own personal copy.
