how splendidly got up! Do write me a line from Berlin. Also thanks for the proof-sheets. I do not, however, mean proof plates; I value them, as saving me copying extracts. Farewell, my dear Hooker, with a heavy heart I wish you joy of your prospects.
Your sincere friend,
C. DARWIN.
[The second edition of the 'Journal,' to which the following letter refers, was completed between April 25th and August 25th. It was published by Mr. Murray in the 'Colonial and Home Library,' and in this more accessible form soon had a large sale.
Up to the time of his first negotiations with Mr. Murray for its publication in this form, he had received payment only in the form of a large number of presentation copies, and he seems to have been glad to sell the copyright of the second edition to Mr. Murray for 150 pounds.
The points of difference between it and the first edition are of interest chiefly in connection with the growth of the author's views on evolution, and will be considered later.]
