HOW THE AUTHOR WAS LED TO 



For myself, I had long hailed, with all my heart, the great French 

 Revolution which had occurred in the Natural Sciences the era of 

 Lamarck and of Geoffroy Saint-Hilaire,* so fertile in method, the 

 mighty restorers of all science. With what happiness I traced their 

 features in their legitimate sons those ingenious children who have 

 inherited their intellect ! 



At their head let me name the amiable and original author of the 

 " Monde des Oiseaux," f whom the world has long recognized as one 

 of the most solid, if not also the most amusing, of naturalists. I 

 shall refer to him more than once ; but I hasten, on the threshold of 

 my book, to pay this preliminary homage to a truly great observer, 

 who, in all that concerns his own observations, is as weighty, as 

 sjtecial, as Wilson or Audubon. 



* Jean Baptiste de Monet, Chevalier de Lamarck, was born August 1, 1744; died
