198 APPENDIX 



CONN : The Method of Evolution. A readable statement of the theory, 

 including its more modern phases. 



HUXLEY: Man's Place in Nature. Giving comparisons between man 

 and the apes. 



Many of Huxley's essays deal with the theory of evolution, especially 

 those collected in the two volumes Darwinians and Evolution and Ethics. 



LLOYD MORGAN: Animal Life and Intelligence and Animal Behaviour. 

 Morgan is a very discriminating thinker in problems of heredity and evolu- 

 tion, and his writings are very helpful as well as very readable. 



LUBBOCK: The Origin of Civilization, also a second volume, supple- 

 mentary to this, entitled Prehistoric Times. Very interesting volumes, but 

 by many regarded as unsound. 



WESTERMARCK: The History of Human Marriage. Largely a reply to- 

 Lubbock's Origin of Civilization. 



T. H. MORGAN: Evolution and Adaptation. Contains an interesting 

 criticism of the theory of sexual selection ; gives a good statement of the theory 

 of mutation; and attempts to minimize the importance of natural selection 

 by advocating the belief that evolution may occur through mutation unaided 

 by natural selection. 



There are many books upon the theory of evolution, but those mentioned 

 are perhaps as important as any for one who is not familiar with the subject. 

 The author knows of no satisfactory presentation of evolution from the stand- 

 point of those who believe in the inheritance of parental modifications. COPE'S. 

 Origin of the Fittest and The Factors of Organic Evolution are two of the most 

 important books written from this standpoint, but they are very difficult 

 reading, almost unintelligible in parts. LE CONTE'S Evolution and its Rela- 

 tion to Religious Thought is written from this point of view, but it is uncritical, 

 assuming rather than discussing the inheritance of parental modifications. 



There are also many books dealing with the phenomena of adaptation r 

 which have such an intimate relation to the theory of evolution. COULTER'S 

 Plant Life and JORDAN and KELLOGG'S Animal Life are written from the 

 point of view of evolution, and are not only valuable for the information they 

 convey, but are very readable and entertaining. KERNER'S Natural History 

 of Plants, translated by Oliver, is a great storehouse of information as to special 

 adaptations seen in plants. It is an expensive, four-volume work, but should
