Darwin's " Origin of Species " has now passed out of 

 copyright. 



It should, however ; be clearly understood that the edition 

 which thus loses its legal protection is the imperfect edition 

 which the author subsequently revised, and which was 

 accordingly superseded. The complete and authorized 

 edition of the work wiU not lose copyright fir some years. 



The only complete editions authorized by Mr. Darwin 

 and his representatives are those pubRshed by Mr. Murray.
