Congenital Anomalies of Arteries and Veins 51 



There may be a tendency to greater frequency of certain vari- 

 ations in some races than in others, but anthropological studies so 

 far made present no convincing evidence. 



In the regions of frequent and wide variation certain studies 

 have attempted to arrange the anomalies in arbitrary classes or 

 types, but this is contrary to the actual condition as shown by 

 careful measurements and is not in accord with our knowledge of 

 development. 



Vascular anomalies have been a great stimulus to the study of 

 development and it is hoped that this paper may be helpful in indi- 

 cating regions where our knowledge is still imperfect.
