power to authorize the publication of it, when and where he 

 chose. The Rule is as follows ; " The author of any paper or 

 communication shall be at liberty to reserve his right of prop- 

 erty therein." (Vide any of the volumes of the Reports of the 

 British Association.) 



That the author had this right, and that he exercised it, is ap- 

 parent from the work having been published in Germany. And 

 the translator had the same right over his translation. The as- 

 sertion, that the author had no power to authorize the republica- 

 tion, is but a feeble apology for interference with the wishes of 

 the author, and, like the other assertions, has no foundation in 

 fact. 



It seems hardly worth while to attend to the insinuations in 

 Messrs. Wiley and Putnam's " Notice," since any effect they 

 were designed to produce, has been so completely dissipated by 

 the pithy reply of Mr. Owen, and the statement of the printers, 

 which was published in the newspapers, and is given below.* 



Messrs. Wiley and Putnam endeavor in their " notice " to 

 convey an impression, that the Cambridge edition was printed, 



* As I understand from the Booksellers, that the public are disposed 

 to wait for the appearance of the Cambridge edition of Liebig's new 

 Work on Animal Chemistry, I should have no motive again to call at- 

 tention to the subject, except to reply to the insinuation of the pub- 

 lishers of the New York edition, that theirs will be used in revising 

 mine. The following statement of the printers may serve to show 

 from what source the revision of my edition will be made. 



J. OWEN. 



Cambridge, August 17, 1842. 



More than one half the pages of Liebig's Animal Chemistry, now 

 printing at our press, was in type before the publication of the New 

 York edition. The printing was commenced and has been entirely 

 done from manuscript, and the corrected sheets sent out by the trans- 

 lator, Dr. Gregory. In no instance has the New York edition been 

 used as copy or to " revise " the proofs.
