8O AUTOBIOGRAPHY. 



in 1839 as part of Fitz-Roy's work. The success of this 

 my first literary child always tickles my vanity more 

 than that of any of my other books. Even to this day 

 it sells steadily in England and the United States, and 

 has been translated for the second time into German, 

 and into French and other languages. This success 

 of a book of travels, especially of a scientific one, so 

 many years after its first publication, is surprising. 

 Ten thousand copies have been sold in England of 

 the second edition. In 1846 my 'Geological Obser-

 on the shores of Portugal. To understand the struc- 

 ture of my new Cirripede I had to examine and dissect 

 many of the common forms ; and this gradually led 

 me on to take up the whole group. I worked steadily 

 on this subject for the next eight years, and ultimately
