312 EMBRYOLOGY 



Chapter 9 



Most textbooks of embryology discuss the early development of the frog 

 egg. However, McEwen's A Textbook of Vertebrate Embryology deals with 

 frog development in more detail and covers a longer period of development 

 than other textbooks. 



Huettner, A. F., Fundamentals of Comparative Embryology of the 

 Vertebrates. Contains many three-dimensional drawings of frog eggs and 

 embryos. 



Chapter 10 



The subject of this chapter is often called neuroembryology. It has re- 

 ceived special attention from embryologists. See the following: 



Detwiler, S. R., Neuroembryology, The Macmillan Company, 1936. 

 Treats the relation of the limb to nervous system, the differentiation of the 

 spinal cord, and the development of function. 



Coghill, G. E., Anatomy and the Problem of Behaviour. Cambridge 

 University Press, 1929. Especially good for the development of function. 



Weiss, Paul, Principles of Development. One section deals with neuro- 

 embryology. 



Huxley, J. S., and de Beer, G. R., Elements of Experimental Embryol- 

 ogy. See the section on the nervous system. 



Chapters 1 1, 12, 13, 14 and 15 



All textbooks of embryology treat with the development of the chick 

 embryo. Lillie's Development of the Chick, however, is more extensive than 

 most and should be consulted for details which are not fully treated in this 

 text. 



For a more detailed picture of the structure of embryos from incubation 

 through 72 hours, see: 



Huettner, A. F., Fundamentals of Comparative Embryology of the 

 Vertebrates. Three-dimensional drawings of chick blastoderms and chick 

 embryos.
