BIBLIOGRAPHY. 



For the general succession of evolutionists, in Philosophy 

 especially, the student is referred to Huxley in his article " Evolu- 

 tion " in the Encyclopcedia Britannica, to Haeckel in his History of 

 Creation, and to Schultze in his Philosophie der Natiirwissen- 

 schaft. Upon the long discussion of the problem of the mutability 

 of species which occurred between the time of Linnaeus and of 

 St. Hilaire, by far the best work is Isidore St. Hilaire's Histoire 

 Naturelle Generate. I have also depended largely upon the full 

 and critical studies of the French evolutionists by Perrier, Qua- 

 trefages, Martins, Varigny, Lanessan. The German natural phi- 

 losophers and poets have been explored for their Evolution 

 tendencies in special studies by Schultze, Barenbach, and Haeckel. 

 Goethe especially has been searched with rich results. We owe 

 to Germany, also, Krause's Life of Erasmus Darwin. To the 

 English writers we owe the articles already mentioned, a number of 

 biographies in the Britannica, Darwin's outline in his introduction 

 of the Origin of Species, F. Darwin's Life and Letters of Charles 

 Darwin, and the vigorous interchange of opinions upon Evolu- 

 tion in theological literature between Huxley and Mivart. In 

 this country Packard has contributed an article to the Standard 

 Natural History, but Lamarckism in America is a subject which 

 still deserves careful study. 



Zeller has given us the most critical and reliable studies of the 

 early or pre- Aristotelian Greek evolutionists. For the later Greek 

 period, I have referred to the general works of Lange anil l-^rd- 

 mann; and to the special studies of Cotterill, Moore, Guttler, 

 Brunnhofer, and others for the later Greek and Mediaeval perio<l. 

 Lewes' Aristotle is a mine of information, yet the author strangely
