[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 I5O/. 



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.]

 owe to you. You will see that I have ventured to dedicate it 

 to you,f and I trust that this cannot be disagreeable. I have 

 long wished, not so much for your sake, as for my own feelings 

 of honesty, to acknowledge more plainly than by mere reference, 

 how much I geologically owe you. Those authors, however,

 second edition is dedicated with and admirable ' Principles of Geo-
