INDEX 



To facilitate the use of this book in connection with others in which the termi- 

 nology may differ somewhat, many synonyms which were not used in the text 

 have been put into the index and cross-referenced to the alternative terms used 

 in this book. For example, Wolffian body, a term not used in this text, is fre- 

 quently applied to the mesonephros. It appears in the index thus: Wolffian 

 body (= mesonephros, q.v.). 



Both figure and page references are given in the index. The figure references 

 are preceded by the letter f .
