CORRESPONDENCE. 



To the Editor of the American Naturalist. 



Sir : — By an unfortunate mistake in my "Lamarck, the Founder 

 of Evolution," it is stated on p. 56 that he died December 28, 1829, 

 whereas the exact date is December 18, 1829. Therefore, on p. 56, 

 line 3 from the bottom, for December 28, read December 18; and on 

 p. 57, line 5, for December 30, read December 20. 



The following is a copy of the Acte de dices: 



Ville de Paris — Anne'e 1829. L'an mil huit cent vingt- 

 neuf, le dix-huit de'cembre, est de'cede a Paris, au Jardin du Roi. 

 Jean Baptiste Pierre Antoine De Monet de Lamarck, membre 

 de lTnstitut, age' de quatre-vingt-cinq ans, veuf. 



Signe: DURANTON. 



Also on p. 9, line 15, for "father" read "grandfather."
